Dear Pilots and Aviation Enthusiasts:      

Paid in Blood

Remember the last time you held a live snake in your hand?  You likely grabbed the snake just behind its head while the remainder of the snake wiggled around your arm.

What could holding a live snake possibly have to do with aviation? 

Think about it.  When you held the snake, did you have a ready plan "B" if the snake began to reach around and bite your arm?  I bet you did!

Sure!  You would let loose of the snake and quickly pull your hand aggressively away.   Whether or not that was the correct thing to do depends upon if the snake bit you!

Snakes and airplanes!

Snakes and airplanes have a lot in common.  They cannot be trusted!  As such, we pilots must always have an instantaneous plan "B" in mind for every stage of flight. 

A sudden engine fire on start-up;  a broken throttle linkage and runaway engine on taxi; a thrown piston rod or broken crankshaft on takeoff; a failed vacuum pump;  a blocked Pitot tube; an out-of-control autopilot;  a bird strike that smashes the windshield in flight; an inadvertent thunderstorm penetration;  a blown tire on landing; extreme turbulence, severe icing, or thunderstorm penetration;  mid-air collision;  gear failure on landing;  deer strike on roll-out;  a runway overrun. 

There are hundreds of ways that airplanes can bite us.

Yes . . . airplanes are like snakes.  Ninety nine percent of the time, they are harmless.  It is the remaining one percent that catch us by surprise.   It is the "surprise" part of flying where the crew and passenger lives are held in the balance.

What about those one percent events?

Anybody with more than a couple hundred hours of PIC time can appreciate those one percent events.  Each one they survived made them a better pilot.  Sadly, some did not survive their particular one percent event.

We pilots would do well to continually focus upon the one percent stuff that happens.  I think about this every time I cross Lake Michigan, fly to the Bahamas, or takeoff over water at night from the Toronto Island Airport.  That's why I always carry a readily accessible life raft.  I also keep a close eye on boats as I cross.

I think a lot about icing in the winter and thunderstorms in the summer.  For me, known ice aircraft certification, stormscope and radar, and turbocharger are comforting friends.  There are plenty of other plan "B" options as well.

Looking down over hostile terrain in remote areas causes me to wonder a lot about SAR (search and rescue) possibilities.   That's why I always know where the roads are and possible emergency landing sites located near those roads. 

And I always carry survival gear.  A handheld radio and back up GPS are also welcomed peace-of-mind items.  Always knowing our location by lat/long coordinates down to the second is a big time saver for rescue personnel!

Taking off into a 200' ceiling?  Do you have your moving map GPS scaled back to one to three miles . . . so you can find a four lane highway in a hurry should your engine fail shortly after liftoff?  Having the instrument approach for my departure airport dialed into my radios or GPS for an immediate return to the airport is a great plan "B" as well.

Having a plan "B" in mind anytime that plan "A" is not working out can spell the difference between inconvenience and unsurvivable.   It provides that golden minute of opportunity that can save the day when the snake strikes.

Sadly, there is not a plan "B" for every possible scenario.  There are those few seconds in every flight where we are hung out on a proverbial limb.  But that's the risk we take as pilots.  Our job, however, should be to minimize these moments of absolute vulnerability by constantly asking, "Do I have a plan "B"?

The 80% factor!

Let's never forget the fact that nearly 80 percent of all fatal accidents are officially attributed to pilot error.  Translated, this means that the lack of proper pilot input is responsible for nearly 80 percent of all fatal accidents.  In many such cases, the pilot simply did not have a carefully worked out plan "B".

Imagine if every GA pilot had a plan "B" worked out for each phase of flight and for every possible flight contingency.  Curiously, we do not see too much of this kind of contingency planning in the private, instrument, or commercial pilot training syllabus.  This is added reason why we should all spend more time in aggressive plan "B" thinking! 

Fly Safe!

Get Intimate with Your
Airspeed Indicator!

You are flying in IFR conditions, scanning a full panel of properly operating instruments.  Suddenly one instrument after another begins to fail.  What would be the minimum complement of instruments you would require?

Answer: 

1. Compass

2. Tachometer/Manifold Pressure

3. Airspeed Indicator

4. Clock or wristwatch

Our first objective would be to maintain a wings level attitude.  If the compass is not turning, the airplane is not banking. 

If we wish to turn from a known heading to another known heading, we simply bank at an angle that allows the compass to turn at 3 degrees per second.  Do the math and you can arrive at your new desired heading.  Admittedly, this takes a bit of practice to achieve.

Our second objective is to maintain altitude.  We can do this by comparing what our tachometer is telling us with what our airspeed indicator is displaying.   

At a known power setting, the airspeed indicator will tell us if we are going up or down.  For example, at full power in a Cessna 172 or Piper Warrior, 60KIAS  would indicate that we are climbing.  Similarly, 130KIAS would indicate a descent.

The same kind of information is calculable at any power setting.  Set the power at 2200RPM in the Cessna 172 or Piper Warrior and level flight will occur somewhere close to 90KIAS. 

Increase power to 2500RMP and pitch to 90KIAS, the airplane will climb at roughly 500 feet per minute (depending up altitude, temperature, and A/C weight). 

Reduce power to 1900RPM, and pitch to 90KIAS, the airplane will descend at roughly 500 feet per minute.   Calculate the number of minutes you need to fly at this descent rate.  By referencing your clock or wristwatch you will arrive closely to your desired descent altitude)

The same power setting principles work in airplanes with constant speed propellers.  Simply substitute manifold pressure settings for RPM.

See the reasoning here?

If we understand the relationship between indicated airspeed and power settings in the airplanes we fly, we do not need an altimeter or vertical speed indicator (VSI) to save the day.  In fact, we can strip the panel nearly bare of instruments and we can still survive in the clouds!

Many of these basic airmanship skills are being lost in today's glass cockpit setups.   We are beginning to lose awareness of the relationship between power, pitch, and airspeed with notable adverse consequence.  Dials are being replaced by scrolling airspeed tapes and engine speed is being displayed digitally.

This makes it doubly important that we are able to compute which power setting and airspeed indications produce level, climbing, and descending pitch attitudes.

Glass cockpit drivers . . . don't allow yourself to become aeronautically dumb!

Basic airmanship requires that a pilot can fly VFR without ANY instruments and that IFR pilots can fly safely in the clouds with only his or her airspeed indicator, compass, tachometer/manifold pressure gauge, and clock.

The best way to master this is to cover all instruments.  Get a safety pilot, put on a hood, and climb up into VFR conditions and practice this until you are satisfied that you can fly safely with a radically reduced panel.

Instruments fail, often at the worst time.  Making do with whatever information we have, even if it means a bit of in-flight calculation, could turn a potential tragedy into a memorable flight.

 

Saving the Worst for Last!

How many times have you grown weary after four or more hours in the cockpit only to face a challenging approach procedure and difficult landing scenario?  It always seems to work that way.  More is expected of us when we are tired than when the day is new and we are fresh!

Learning to pace ourselves . . .

Frequent OTA readers know that I have little regard for any form of simulated training in anything short of a full-up airline type simulator.  A 1.5 hour work out in the practice area or, worse, an hour sitting in front of a stationary simulator cannot compare to what we experience following a four or five hour flight, in the scud, often ending at night when we are physically and mentally exhausted.

Everything is working against us on long cross-country flights.  The weather is changing, fuel management is always an issue, we have to (pardon me) pee, and we're just plain tired.

Not only are we physiologically exhausted, the gap between our piloting task requirements and our pilot capabilities narrows dramatically as we transition from cruise to the approach and landing phase of flight.

Learning to pace ourselves for long cross country takes lots of practice.  Some things to keep in mind are shown in the table below:

Set limits for your duty day: Never commence a long cross country flight that will require a landing more then 14 hours after waking in the morning.  And always get a good night's sleep prior to any long cross country flight.
 Dress for flight: Most of my non-instructional flying is for business, which requires me to wear a suit and tie.  I always fly in casual attire and allow time to change prior to a destination business meeting.
 Carry food and water: Adding hunger and thirst to the list of physiological needs could be the back-breaking straw!  Always keep healthy snacks and water in the cockpit.
Portable Johns and Janes: None of us are immune from unscheduled bathroom needs.  Use your imagination . . . but be prepared!  Modesty can be protected with a blanket or even a quick front to back change of seats.
Carry portable oxygen: Humans begin to show declining blood/oxygen concentrations at altitudes as low as 8,000 feet.  Having supplemental oxygen aboard can help to mitigate the effects of lengthy stays in nonpressurized airplanes operating at or above 8,000 feet.

The last segment could be the deal killer!

Do whatever it takes to prepare yourself for the last flight segment.  Get set up early for the approach.  Have everything you need close at hand and properly arranged, e.g., approach plates, FBO selected with frequency, flashlight, etc.

Leave nothing to chance!    

 

 Happiness is . . . a New Bo!!

You are looking at one very excited family!  My good friend, Mark Weissman of Grand Island, NY, with his wife, Lynn and twin children Brandon and Brianna, is receiving the keys to his new (new to him) 1989 A-36 Beech Bonanza.

Mark is stepping up to the Bo from a Piper Archer that he sold about 8 years ago.  For him, the challenge is not only to regain his pilot currency, but to also become proficient with this high performance, six place aircraft.

New fun . . . added responsibilities!

Mark is a physician (Ob-Gyn).  Does that tell you something?  You bet!  Doctors are inherently self-confident, high achieving individuals.  Doctors also have nasty reputations for bringing their self-confidence into the cockpit where this trait brings no special piloting skills.  An over abundance of self-confidence is, in fact, the greatest enemy of safe flight.

Mark is keenly aware of this fact.  He is an inherently good pilot, and he has secured the best recurrent training possible. Others in this category, however, may not be as prepared.  The A-36 Bonanza, like any high performance single or twin, is not a basic, two or four place trainer.  It is designed to go fast and carry more weight.  Its safe operating envelope is narrower and its design margins for error are smaller.  Its systems are more complex and there are more of them.

Becoming proficient in high performance airplanes is only one small part of the process. Maintaining one's proficiency is another story altogether. 

10 to 12 hours per month!

Despite Mark's enormously busy medical practice and the time demands it places on him, he and Lynn are both well aware of the fact that he must fly a minimum of 10 to 12 hours a month to realistically maintain his proficiency in the Bonanza.  Adding instrument proficiency to the mix requires even more time in the air each month! 

It's easy to log 10 to 12 hours a month if you take weekend trips.  If you don't, then commit yourself to a regular two hour in-flight workout at least once a week.  And if you cannot accomplish this, then maintain a relationship with a skilled CFI who can provide challenging workouts at least once monthly.

High performance airplanes are fun . . . but they require an added recurrent training requirement.  Mark will do well with his Bonanza because he understands the risks and trains hard to mitigate those risks.  We need to follow his example!

 

Become a Cloud
Savvy Pilot

One of the most important attributes of a proficient pilot is knowing the different cloud types and their various characteristics.  Being able to "read the clouds" goes a long way in predicting weather conditions along your planned route of flight.

How clouds are formed

Three ingredients are necessary for clouds to form.  One is adequate water vapor.  The second is condensation nuclei.  The third is a method by which the air can be cooled.

When the air cools and reaches its saturation point, the invisible water vapor changes into a visible state.  Through the processes of sublimation and condensation, moisture condenses on particles of matter such as dust,
salt, and smoke known. 

Cloud Types

Cloud type is determined by its height, shape, and behavior. They are classified according to the height of their bases as low, middle, or high clouds, as well as clouds with vertical development.

Low Clouds: 

Low clouds are those that form near the earth’s surface and extend up to 6,500 feet AGL. They are made primarily of water droplets, but can include supercooled water droplets that induce hazardous aircraft icing.

Typical low clouds are stratus, stratocumulus, and nimbostratus. Fog is also classified as a type of low cloud formation. Clouds in this family create low ceilings, hamper visibility, and can change rapidly. Because of this, they influence flight planning and can make VFR flight impossible.

Middle Clouds:

Middle clouds form around 6,500 feet AGL and extend up to 20,000 feet AGL. They are composed of water, ice crystals, and supercooled water droplets. Typical middle-level clouds include altostratus and altocumulus.

These types of clouds may be encountered on cross-country flights at higher altitudes. Altostratus clouds can produce turbulence and may contain moderate icing.  Altocumulus clouds, which usually form when altostratus clouds are breaking apart, also may contain light turbulence and icing.

High Clouds:

High clouds form above 20,000 feet AGL and usually form only in stable air. They are made up of ice crystals and pose no real threat of turbulence or aircraft icing. Typical high-level clouds are cirrus, cirrostratus, and cirrocumulus.

Clouds with extensive vertical development are cumulus clouds that build vertically into towering cumulus or cumulonimbus clouds. The bases of these clouds form in the low to middle cloud base region but
can extend into high altitude cloud levels.

Towering cumulus clouds indicate areas of instability in the atmosphere, and the air around and inside them is turbulent. These types of clouds often develop into cumulonimbus clouds or thunderstorms.

Cumulonimbus clouds contain large amounts of moisture and unstable air, and usually produce hazardous weather phenomena such as lightning, hail, tornadoes, gusty winds, and wind shear. 

These extensive vertical clouds can be obscured by other cloud formations and are not always visible from the ground or while in flight.  When this happens, these clouds are said to be embedded, hence the term, embedded thunderstorms.

Proficient weather pilots read clouds like they read the newspaper.  Each form or type of cloud is predictive of the ride ahead. 

Most clouds are safe to pass through.  Others are sleeping bears capable of dismembering even the largest aircraft.  Be sure you know the difference!

 

 

Monkey See, Monkey Do!

I was standing on the ramp at a local airport recently observing a flight student and instructor boarding an aircraft.  Both the CFI and the student positioned their headphones squarely over their ears BEFORE starting the engine.

The engine started and idled for a couple of seconds.  After that, either the student or the CFI advanced the throttle on this still cold engine to high RPM and began what appeared to be a mag check.

Do you see anything wrong with this picture?

Sure you do.  First, with headphones on, particularly those with active noise attenuation, the pilot(s) may not hear the quirky little sounds that worn gyros make when spooling up, or the squeaking sound of an oil-starved engine bearing, or the many other subtle warning sounds that originate under the cowl on engine start up.

Then there was the racing of a cold engine.  I wondered if the flight school owner knew the damage his CFI was doing to his aircraft.

Many of the bad and oftentimes risky habits we observe in GA pilots were planted by inexperienced CFIs demonstrating bad practices.  "Primacy of learning," which suggests that those items learned first make lasting impression, is the underlying culprit.   Those first few actions of the CFI often carry through the entire flying life of his or her students. 

Worse, some of those badly infected students go on to become bad CFIs who perpetuate the problem.

You can fix the problem by speaking up!

Several years ago a veteran pilot came up to me and said, "Bob, forgive me, but I see many of your students doing cockpit checks while sitting in front of the gas pumps.  This is annoying to other pilots waiting to get fuel."

You know, he was right.  He pointed out a bothersome oversight in my own flight training example.  From that point on, I always instruct my students to taxi away from the fuel pumps immediately after fueling.

The CFI sets a powerful example.  What he or she does, flight students do as well.  If you see a bad practice being exhibited by a CFI, speak up!

 

 

Too windy to fly . . . Never!

Every so often a student pilot will proclaim to me that we cannot fly today because the winds aloft are blowing at 40 or 50 knots.   "Why not," I reply?

"Well . . . it's too windy up there.  We'll get tossed around too much," comes their hapless reply.

The effect of upper level winds

Apart from storms and associated turbulence, winds aloft have only two effects on airplanes in flight.  One is ground speed and the other is course to steer.  

There is nothing inherent in high winds aloft that threaten even the lightest, least powerful airplane!

The illustration to the right shows how ground speed is influenced by winds aloft.  Note that the illustrated airplane continues to travel through the air at 120 knots regardless of the air flow speed around it.

When does wind become a factor?

Wind becomes a factor to aircraft in flight when:

1. Taking off and Landing:  The direction of the wind relative to the runway has a significant effect on airplanes in flight.

2. Heading to Fly: If there were no winds aloft, we could simply point the airplane to our destination and wait out the required time to traverse the course.  Obviously, this is seldom the case.  There are nearly always some winds aloft.

3. Fuel Considerations:  Anybody who has faced a 60 knot headwind understands the effect of winds aloft on time to destination.  And time aloft translates to the amount of fuel required to make a given trip.

4. Emergency Glide Distance:  Have you ever crossed a wide body of open water without considering the winds?  Of course not.   You know precisely which direction to fly should the engine quit, right?

Wind awareness at any stage of flight, whether taxiing or cruising aloft, is a sure sign of pilot proficiency.  He or she knows precisely what the winds are doing to the airplane at any point in time.

A proficient pilot understands winds, why they happen, and where they are coming from!  He or she also knows, however, that apart from turbulence or thunderstorms, winds aloft have little bearing on the safety of flight.

 

Gone West . . . Tracy Dart

The Western New York flight training community lost one of its finest talents this past month.  Tracy Dart, age 36, was providing primary flight instruction to a 17 year old student in a Taylorcraft at Dart Field near Mayville, NY.   A suspected engine failure on takeoff caused the tail wheel aircraft to descend and strike power lines and trees.  She died at the scene.  Her student survived with serious head and chest injuries.

Tracy was a pretty lady with a ready smile and a happy greeting for everybody she saw.  Well known for her expert tail wheel instruction, Tracy, daughter of airport owner Bob Dart, will be deeply missed.

A memorial service at Dart Field will be scheduled in the coming weeks.  A special OTA announcement regarding this service will made as soon as details become available.

 

Night IFR . . . Beware!

One has to wonder what was going through the minds of the FAA when it formulated the Practical Test Standards (PTS) to qualify for an instrument rating.  No night IFR training is specified in the PTS!

Night IFR is one of the most challenging of all flight environments.  Aside from the fact that cockpit lighting is notoriously poor, night illusions can trick even the most weather-beaten, jaded instrument jock.

Yet there is no requirement in the instrument PTS for night IFR training.  Flight schools and independent CFIs are free to sign off instrument students with no night training at all.

And we all know that nearly all instrument check rides are given during daylight hours.  So how do we know that we are proficient at night IFR flight?  Trial and error?

Night illusions are everywhere!

AUTOKINESIS:  This is caused by staring at a single point of light against a dark background for more than a few seconds.  After a few moments, the light appears to move on its own.

FALSE HORIZON: A false horizon can occur when the natural horizon is obscured or not readily apparent. It can be generated by confusing bright stars and city lights.  It can also occur while flying toward the shore of an ocean or a large lake. Because of the relative darkness of the water, the lights along the shoreline can be mistaken for stars in the sky (see illustration above).

NIGHT LANDING ILLUSIONS:  Landing illusions occur in many forms. Above featureless terrain at night, there is a natural tendency to fly a lower-than-normal approach.  Elements that cause any type of visual obscuration, such as rain, haze, or a dark runway environment also can cause low approaches.

[Photo right is of Ames, Iowa at night from 15,000'.]

Bright lights, steep surrounding terrain, and a wide runway can produce the illusion of being too low, with a tendency to fly a higher-than-normal approach.  Often a set of regularly spaced lights along a road or highway can appear to be runway lights. 

Pilots have even mistaken the lights on moving trains as runway or approach lights. Bright runway or approach lighting systems can create the illusion that the airplane is closer to the runway, especially where few lights illuminate the surrounding terrain.

Weather avoidance at night is problematic

By definition, IFR flight involves complications.  When these complications occur at night, the "see and avoid" rules no longer apply.  Thunderstorms on moonless nights cannot be seen, therefore without ATC assistance they cannot be avoided.

Turbulent build-ups hidden by the dark of night can startle the instrument pilot to the point of causing disorientation and loss of aircraft control.

Become IFR night proficient . . .

The differences between day/night VFR flight versus day/night IFR flight are profound.  Dim cockpit lighting makes charts and plates difficult to read, weather is more difficult to avoid, and the ever-present night illusions make night IFR flight a bigger challenge than most pilots believe.

Like all such challenges, they are best addressed head by aggressive initial and recurrent training.  Contact your favorite CFII and go out and fly IFR at night until you become absolutely proficient!

 

 

Instant Weight and Balance

Weight and balance is the one thing many GA pilots take for granted.  We believe that if we can fit it in the airplane, we can fly.  This particularly true with legendary haulers like my Cessna T-210. 

Every student pilot eventually learns the principles of weight and balance before he or she takes the checkride.  After the cherished certificate is received, W&B take a literal backseat in the minds of most pilots.

Vowing never to take off over-gross, a situation comes along where the limits of the loading envelope get pushed out a bit.  The hapless pilot instantly becomes a test pilot and, whether he knows it or not, his insurance company may be off the hook for any resultant damages. (Remember, aircraft insurance operates differently than automobile insurance.  To remain covered, we pilots are restricted to operating our a/c within prescribed limits of performance!)

Be Prepared - Always compute a weight and balance

Anybody with a Palm Pilot, iPac, or similar handheld computing device can quickly and easily compute a weight and balance on the fly.  Simply create a mini-Excel spreadsheet.  Then plug in the variable numbers, press "compute" and you instantly have your total weight and moment!

Remember WAM!  [Weight x Arm = Moment]

 

With the total weight and moment, refer to the loading graph.  Plot the weight on the vertical (Y) axis and the moment on the horizontal (X) axis and, bingo, you're good to go. 

If your computed plot takes outside of the envelope, don't fly.  Instead, adjust your load (fuel/passengers/baggage) accordingly.

 

A word about overweight flight!

There is no question that, given enough runway, an airplane loaded 20 to 30 percent, or even 50 percent overweight will fly, leastwise in ground effect.  It may actually climb to cruise altitude.  But what are the risks of overweight operation?

The first risk is . . . . will it climb out of ground effect?  What will happen once the overweight airplane reaches the end of the runway.  Will it climb out of ground effect and clear any obstacles?

The second and more insidious risk is the effect of excess weight on the structural integrity of the airplane.   We know, for example, that the G loading on an airplane equals 1 in level, unaccelerated flight.  This means a fully loaded 2,500 pound airplane weights 2,500 pounds in level flight.

The problem of excess weight occurs when we add G forces to the airplane.  We know, for example, that the G forces doubles when in a 60 degree bank.  In this flight attitude, our 2,500 pound airplane now weights 5,000 pounds.  Roll over into a 70 degree bank and the airplane suddenly weighs 7,500 pounds.

Aircraft designers, of course, are well aware of the load forces placed on an airplane.  They design the structural strength accordingly.

What about the overweight aircraft?

Let's take our 2,500 pound gross weight airplane and overload it by 200 pounds.  In a 70 degree bank, those 200 pounds now weight 600 pounds.  This added load could be enough to cause structural damage and possibly an airframe component failure in flight.

Reference to the VG diagram below illustrates how G loading is affected by airspeed.  Note that aircraft certified in the normal category at maximum gross weight must be able to withstand a positive 3.8gs and a negative 1.52gs.  Adding even one pound of excess weight takes the airplane out of its certification range!

While and overweight airplane is problematic for the reasons noted above, equally serious consequences can occur if the center of gravity (CG) is outside the published loading envelope . . . even if the total weight is within prescribed limits.

An aft-loaded (meaning the CG is behind the loading envelope) may be difficult to control.  Worse, it may not be able to recover from a stall. 

All things considered, operating an airplane outside of its W&B limits not only bad practice, it is also illegal.  Remember, you are fair game for an FAA inspector to walk up and request a copy of your weight and balance computations.  You better be prepared!

 

Women Soar!

What does a working mom with three teens at home do with her spare time?  She learns to fly! 

That's just what Liz King of East Aurora, NY did this past winter.  Standing with me last week on the day she received her private pilot certificate, she is one very proud lady.

She should be.  Liz, like so many other flight students, suffered through several flight instructors before she found one who would stick it out with her. 

Credit EAA Chapter 46

Much of the credit for Liz's flying success comes from her many friends in Buffalo's EAA Chapter 46.  She received lots of support and encouragement (and advice) at each meeting and social event.

Local EAA chapters provide countless hours of support to pilots and aircraft builders.  Events such as the EAA 46's cookout last week at Buffalo's Lancaster Airport bring fledgling pilots, veterans, and aircraft builders together in a mutually supportive fashion.

Meet us at Oshkosh!

The EAA 46 Oshkosh compound will be up and operational this year as usual.  As many as 60 chapter members and friends will pitch tents and park campers around the giant green and white circus tent in the Scholler campgrounds located near the Theater in the Woods.

Family style breakfasts and dinners are expertly prepared and served each day of the event.  This year will feature a full-fledged pig roast.  Please be sure to stop in and say hello!

For more about EAA Chapter 46's many activities, click HERE.  By the way, EAA 46's website was designed by Liz King's husband, Bill.  Need help in website design, contact Bill at williamking@adelphia.net.  Photo credits Jim Cavanaugh.

 

 

Controllers Screw Up
 Too - Pay Attention!

Air traffic controllers do not make mistakes very often, but when they do . . . watch out! 

Such was the case on a routine instrument training mission this past week.  My student and I were on an IFR flight plan enroute to the Bradford, PA (KBFD) airport located in northwest Pennsylvania.  It was a beautiful day.  My student was under the hood.

We called Cleveland Center and requested the ILS Runway 32 approach.  The controller descended us to 4,000 feet and issued the first vector enroute to the final approach course.

I used this time to implore my student to ALWAYS be aware of his position relative to the plan view on the instrument approach plate.  The timing of this lesson could not have been better!

We were about six miles from making our final turn to the inbound course when the controller called us and said, "Nxxxx, I have lost radar contact with you.  Squawk VFR and fly the approach visually."

Huh . . . . I looked at my student and said "She can't do that.  We're on an IFR flight plan!"

I queried the controller.  "Ah, Cleveland Center, we'll fly the approach as published.  Request direct to the Bradford VOR."

"I said I have lost radar contact with you.  I cannot clear you for the approach.  Squawk VFR and fly it visually," she retorted.

Rather than debate the issue with the controller on the radio, I simply complied with her instructions and asked for her telephone number.  

Upon landing, I telephoned Cleveland Center and discussed the incident with the supervisor.  He quickly acknowledged the fact that ATC cannot cancel a pilot's instrument flight plan (except upon landing at a tower controlled airport).  He further affirmed that the controller's actions were incorrect and apologized for any inconvenience caused by this incident.

Okay, we'll chalk this one up to a rookie controller making a mistake.  All of us do this from time to time.  The important point for us pilots to remember is to ALWAYS be aware of our position.  

Equally important, we must never surrender our PIC authority to ATC.  We're in charge here.  Sure, we have a responsibility to comply with ATC issued instructions, but ONLY when they make sense to us!  If these instructions do not make sense to us, request a clarification or simply say, "Unable."

In the incident described above, had we been in IFR conditions without knowing our position, the outcome might have been tragic.  The controller would have likely been de-certified and things could have gone a lot worse for us! 

 

Density Altitude - Beware!

For OTA readers in the northern hemisphere, we are entering the hottest weeks of the summer.  Correcting pressure altitude (weight of the atmosphere) for non-standard temperature can exact a very big performance price from your airplane.

Remember the steps in determining density altitude

1. Determine the pressure altitude for your airport by dialing 29.92 in the Kollsman window in your altimeter and read the displayed altitude.

2. Locate the pressure altitude diagonal line on the chart to the left.

3. Slide up or down this line to a point atop the outside temperature shown on the horizontal (X) axis on the bottom.

4.  Read the corresponding density altitude on the vertical (Y) axis.


In summary, as the temperature climbs, so does density altitude.  This will have a direct effect on ground roll distance and climb rate.

Be sure to check your aircraft's performance tables in your POH before operating on a hot day!

 

 

 

 

 

Simulated Training
- Keep it safe!

One would expect that a 7,300 hour CFI with ATP working for the Beechcraft Pilot Proficiency Program (BPPP) would have sufficient experience and skill to preclude a fatal stall/spin in a training exercise.  Such was not the case several years back in Jackson, Ohio.

The training exercise that led to the death of both the instructor and the pilot/owner of a Beech A-36 Bonanza was a simulated engine failure after takeoff and an emergency return to the airport.

Witness Statements:

One witness observed the "smooth, level takeoff," and noted that the engine was "really humming," and appeared to be at "full power." The airplane was in a "nose-up" attitude during the climb, and reached an altitude of about 1,200-1,300 feet [AGL] before it pitched down and impacted trees.

A second witness observed the airplane depart, then turned his attention away from it. When the witness looked back at the airplane, it was about 200 feet above the tree line, "descending vertically and rotating."

A third witness, who observed the airplane during its second takeoff climb, stated that it appeared the airplane "entered a stall," and its nose "dropped" into a continual right bank turn until it impacted trees. The witness also reported the engine was "solid-sounding" and he heard no interruption of power.

Airplanes do not stall/spin by themselves!

Given enough altitude, there is nothing inherently hazardous about initiating a 180 degree turn back to the airport in the event of engine failure on takeoff.  But two immutable conditions must be met.

The first condition is, the airplane's pitch attitude must be kept below the critical angle of attack to preclude a stall.  Remember, stall speed increases with bank angle.   The other requirement is to insure that the turn back to the airport is coordinated, e.g., centered ball in the slip/skid indicator.

Each of these requirements are easily achievable.  The stall is prevented by keeping close attention to the airspeed indicator (which is always primary for climb).  The bottom of the green arch on the airspeed indicator displays the stall speed.  Again, remember that stall speed increases dramatically with bank angle.

Similarly, the spin is prevented by keeping a close eye on the slip/skid indicator.

While an airplane can be made to stall at any airspeed, operating anywhere near the bottom of the green arch on the airspeed indicator places the airplane at substantial stall risk.  Simply put, don't go there.  Instead, lower the nose to instantly increase airspeed which, of course, reduces the angle of attack below the critical angle.

Stall Speed Increases with Bank Angle (load factor)!

The chart below illustrates the relationship between load factor and stall speed.  The yellow line shows by example that a 3G turn (70 degree bank angle) in this particular airplane increases the stall speed from 45 knots to 70 knots!

Assuming the accident pilot entered a steep bank angle on his return to the airport, it is easy to see how a stall could have resulted.  Adding any element of a yaw (non-centered ball in the slip/skid indicator) in this turn would have likely precipitated the spin!

There is only ONE safe way to practice the 180 degree power off return to the airport.  That way is to perform the maneuver at least 3,000' AGL.  This insures adequate altitude should the maneuver not work out as planned.  Simply use your altimeter to assess altitude loss in the turn.

Caution about emergency training

The accident record reveals far too many fatal accidents resulting from aggressive flight instructors attempting to inject too much realism in their emergency training exercises. 

Realistic emergency training is important, but two conditions must first be met:

1. The CFI requires consummate piloting skills.

2. Emergency maneuvers training should only be performed where adequate altitude and/or backdoors exist.
 

 

Quotable

"There are plenty of people with wide audiences who try to sugar coat the accident record and somebody needs to tell it straight."
       -- Richard L. Collins, Editor-at-Large, Flying Magazine, July, 2006

Truth in advertising has become part of the fabric of nearly every industry from medicine, to merchandising, to banking, and to airline travel.  Consumers are protected from unsubstantiated claims, hidden costs, undo risks, and every other effort to mislead the buying public.    

Then we have general aviation . . . an industry that seems to operate under a different set of consumer rules.  Here, consumers are aggressively recruited, seduced by promises of fast training, speed, and a fool-proof guarantees of safety.   Every component of general aviation, from aircraft manufacturers to flight schools paint a yellow brick road to the Wizard of Aviation Happiness!

Public not buying it!

Not surprisingly, the public is not buying it.  While the spin-meisters of general aviation would like us all to believe that the industry is booming, it isn't.  New pilot starts are down 58 percent from their peak in 1979.   Even the total number of licensed pilots is down 25 percent during the same period despite a 35 percent increase in the total population.

Curiously, a continuation of this negative pilot trend will result in a very serious shortage of commercial and airline pilots in the coming years!

Maybe it is time that general aviation follow the lead of other industries and freely admit its own associated risks.  In so doing, the consumer view of general aviation might shift from suspicion and fear to open awareness and a commitment to mitigate risks through aggressive initial and recurrent training.  

Let's begin telling it like it is!

Instead of sugar coating the accident data, let's come clean and report that, based upon NTSB accident data, a person stands a 100 times greater risk of a fatal accident in a light general aviation aircraft than he does in an airliner.   Let's boldly tell our pilot community that nearly 80 percent of all fatal accidents occur because of pilot error. 

Remember, statistical information can be spun in any direction the writer chooses.  Substituting accident numbers for accident rates can be extremely misleading!

Let's begin telling consumers that much of the general aviation flight training system is in disarray with rank beginners serving as flight instructors and a recurrent training virtually non-existent for a vast majority of our pilots.

Wow . . . . nobody would fly if that was the message we send out to the public!

Not so.  When consumers know and understand the risks of any endeavor, whether it be flying, skiing, playing football, parachute jumping, or scuba diving, they respond appropriately by taking adequate safeguards.  But they first must know the risks! 

Light Sport . . . hmmm!

Many aspects of the new light sport program are great, but elements of it illustrate general aviation consumerism gone wrong.  

Imagine, a person can walk in off the street and be licensed to fly himself and an unsuspecting passenger with a mere 20 hours of instruction.   And no medical examination is necessary!  

Any aviator who believes in the 20 hour minimum training rule has spent too much time at high altitude with a pinched oxygen tube!  

In truth, the light sport program IS safe when pursued by proficient pilots with adequate primary and recurrent training.  Anything short of that (and 20 hours of instruction is far short of that) is downright dangerous. 

Not so, says the EAA and AOPA, strong advocates of the light sport program.  And that's what they convinced the FAA.  Let's wait and see . . .

Stall/spin training, alone, requires at least five or six hours to complete.  Add emergency procedures, rudimentary navigation, ATC procedures and communications, weather factors, and basic maneuvering skills and you have a solid 40 hour in-flight curriculum! 

Remember, from a safety perspective, there are very few things that a private pilot can do that a light sport pilot cannot do!

Let the truth be told!

Somewhere in this new program consumers need to be told the truth about the inherent risks of flight.   Then, when they know the risks, they can scoff at the 20 hour training bit and go out and find competent instruction.  The same holds true for all levels of general aviation.

We pilots, too, need to be frequently reminded of the inherent risks of any incapacity, oversight, or neglect in our operation of airplanes.  Complacency is the arch enemy of any pilot, young or old.  A quick flight with a missed preflight can stop us in our tracks . . . . for eternity.  When the risks of flight are upper most in our mind whenever climbing into the cockpit, the likelihood of an accident are dramatically reduced.

A call to action . . .

We consumers, for the most part, are very bright people.  We demand honesty and integrity in all of our business dealings.  Mess with us by under-playing the facts and we will take our discretionary dollars elsewhere.    And, sadly, that is what's happening in general aviation!

But we can change all of that.  Flight schools and independent flight instructors, we should lay it on the line to our prospective and current students.  Let them know that speed kills.  When combined with altitude, the risks of nonproficient flight are enormous.  On the other hand, secure optimal instruction and engage in annual recurrent training, the risks can be substantially reduced.

Big GA organizations with wide audiences have done great things for general aviation.  Regrettably, however, some are actually impeding our progress by telling the FAA that added initial qualification and recurrent training requirements represent an undo burden on pilots. 

Sure, we need to pay attention to what is, in fact, relevant training.  But let's not be contrary to valid efforts to improve safety. 

Next, all pilots, through our membership dues, influence the big organizations who speak for us.  Whenever we observe a sugar coating of the facts, a positive spin put on the accident data, or an overt effort to lessen the training burden on us pilots, take note. 

Sure, many of us are able to police our own training and proficiency requirements.  We do not need the FAA to mandate what we already know and do.  Unfortunately, we're in a solid minority among GA pilots.  The vast majority of private pilot certificate holders are . . . . well, let's just say in need of a tune up!

The next time some spokesman for general aviation stands before you at a pilot safety meeting and proclaims that everything is hunky dory safety-wise in general aviation, challenge his or her facts.  Let your membership dues speak for you!

When enough of us do this, general aviation safety will improve and our industry will begin to thrive.

The following reader comments were received over the past two weeks:

International Readers:


"I am a student pilot taking training in Okinawa, Japan. This is the first time I have visited the site. It contains some very interesting, and more importantly, very useful information. Keep up the good work.
-- Frank Duvall, Okinawa, Japan


"Came across Over the Airwaves on a Google search and am hooked. Really appreciate your emphasis on training requirements for aviation safety. As a dad this is critical for myself or my daughters who may want to train some day, too.  Thanks to Over the Airwaves, I now know how to intelligently  choose a CFI / flight school."
--  David Venish, Sydney, Australia


United States Readers:

"I am happy to see someone who goes head-to-head with the FAA and teaches more than the PTS. Thanks."
-- Sotirios Steven Molos, Fort Dix, New Jersey


Over the Airwaves was emailed to every flight operations major attending the University of Dubuque by one of the staff members.  I really enjoy the large amounts of knowledge I can get out of something so simple. A lot of this information cannot be obtained in a classroom or out of a book."
-- Kevin Bradford, Dubuque, Iowa


"I am an aviation insurance executive and wanted to let you know I feel your observations and advice are on target from our perspective.  Also, it is refreshing to see someone look behind the obvious issues and try to address the underlying thought process that leads to accidents.

Best of all, your comments are a healthy dose of reality in what is often a "see no evil, hear no evil, speak no evil" GA environment.  I look forward to receiving future editions of your newsletter."
--
Lauretta Godbey, VP, Marketing & Public Relations, Avemco Insurance Company


"A pilot friend forwarded a copy Over the Airwaves to me. It is a fantastic website! With a wealth of information, ideas, and just good reminders we all need. I sent it to 150 of our local aviators.  Thank You!"
-- Dick McColley, Sierra Vista, AZ


"As the Safety Officer of the Maxwell Air Force Base Aero Club/Flight Training Center I have found ideas for several safety briefings in Over the Airwaves. My thanks for your help."
-- Cliff A. Chambliss, Montgomery, AL


"I am also a CAP member and the Safety Officer for my squadron. This newsletter will be beneficial for our folks."
-- John Maxfield, Raleigh, North Carolina


"I always look forward to OTA and your non-politically correct writing style."
-- Gordon Daniel Young CFII, Rochester, NY


"I heard about Over the Airwaves from the AOPA Flight Training publication. After reviewing the online sample, I definitely think it's an essential service. Straight talk with clear thought!"
-- Dan Burkett, Thornton, CO


"A friend emailed Over the Airwaves and highly recommended it as a rich source of good pilot information."
-- Jon M Nelson, Sierra Vista, Arizona


"I ran across Over the Airwaves while doing a Google search. Great Stuff!! I look forward to learning a lot.  The little bit I've read thus far confirms I need some spin training.

I've got 600 hours, IFR Rated, and hold a commercial ticket. Know how many times I've spun a plane??  ONCE...and that was several years ago!  My friend and CFII doesn't like to do them, so we don't. Guess I need to find a CFI who will do this with me."
-- Rob Stone, Dover, PA


"I just finished the 6-11-06 edition of "OVER THE AIRWAYS" and as usual I feel that I have completed an outstanding aviation seminar. I don't fly as much as I once did, but "OVER THE AIRWAYS" sure fills in a lot of gaps for me.  I do not believe anyone could read and absorb your many safety articles and not be a better pilot as a result!  Probably the most important benefit for me is the articles make me think and study."
-- Ken Rice, Fort Worth


"I've thoroughly enjoyed reading this issue of Over the Airwaves and look forward to new issues and reading the archives as well. You've done a great job."
-- Leon Harris, Grayson, GA


 "I heard about "Over the Airwaves" in the AOPA Flight Training magazine article. Very impressive."
-- James Sutherland, Niagara Falls, New York


"Over the Airwaves is wonderful and opens doors and thoughts to those of us that need it. Thank you!
--Jim Ruby, Sierra Vista, AZ


"Excellent site, wealth of information.  How about an rss feed for the site?"
-- Rich Macken, Snohomish, WA


"I usually experience some level of anxiety when I read a topic (such as 'Spins') wondering whether my reactions in an actual situation would be appropriate. Thanks for the "wake-up call". Wish you were closer to Arizona .... you would be a great "in cockpit" resource."
-- Don Schaefer


"VERY Good Info and VERY well presented!  I became aware of "...The Airwaves" from a CFII friend of mine. Thanks!"
-- Roger M. Heard,  St. Joseph, Missouri


"I saw a reference to Over the Airwaves in "Flight Training" magazine.
I know I will assimilate good information from your website and articles."
-- Ken Corcoran, St. Louis, MO


"Unfortunately you put in that Red Skelton bit which clearly has nothing to do with flying. I truly appreciate your effort in this newsletter, Bob. I have a difficult time accepting that someone who writes such a wonderful and logical and beneficial publication can promote something so irrational.  Imagine a pilot inadvertently entering a thunderhead, suddenly letting go of the controls and praying for deliverance! Consistency is the best policy!
-- Hutchinson Parsons
 

Reply:  Hutchinson, you missed the point of the Red Skelton piece. You have the freedom to publicly admonish references to prayer as I have the freedom to publicly promote increased awareness of the privilege we all have to fly. We live in a free country . . . . and these freedoms are slowly being eroded by those who forgot the high price paid for such.

The Pledge simply affirms the fact that the people elect the leaders. We must never, ever forget that. If we do, we will lose our freedom to fly.

Is the Pledge of Allegiance, as written and recited, relevant to flying? Spend a couple of days with some young people in China or Cuba or Libya (where civil aviation is prohibited), then answer that question!

The Pledge of Allegiance has everything to do with our freedom to fly in America. It enables me to build and fly an experimental airplane and to land it in any civil airport in the nation (except DCA . . . . which is very troubling to me).

Take away the Pledge or, more importantly, what it stands for, and we private pilots will soon be grounded, I promise you that!

-- Bob Miller
