Vol. III No. 19 |
Welcome
to the
Over the
Airwaves
aviation journal. This complimentary bi-weekly e-mailing
is being sent to pilots and aviation enthusiasts around the
world. Its aim
is to promote
flight safety, encourage students and new pilots, and to build
enthusiasm for aviation in general.
Dear Pilots and Aviation Enthusiasts:
We have an average of five serious general aviation accidents a day in the U.S. One of these involves fatalities. Who's to blame? Does the blame fall upon the hapless pilot who forgot to check his fuel load, or found himself in a fatal stall/spin, or was a bit lax in the aircraft maintenance department, or who wasn't looking out the window, or who overshot the runway? Sure, it was the pilot. That's what most people conclude. He or she was the PIC and, by regulation, he is ultimately responsible for the safe outcome of every flight.
No? Okay, let's blame the airport operator for improper airport signage, wind direction aids, or bad runway lighting. Some manage to hang the blame on some poor air traffic controller for failing to call out an incorrect runway to a departing pilot, or timely wind direction advisories, or for missing a read-back error. Of course, there is always the flight training community. There is certainly a lot of blame we can hang on inept CFIs for failing to impart even rudimentary stick and rudder skills or the flight school that shuts down training when the winds kick up a bit. Moving closer to the beginning of the accident chain, we could blame the FAA for faulty or short-sighted regulations. Hey, the guy tried to take off in zero-zero conditions. Blame it on permissive FARs! Then there are the big GA alphabet organizations like AOPA, ASF, EAA, and GAMA. They like to put a positive spin on the GA safety record. Perhaps they are holding the smoking gun. Let's blame it on the U.S. Constitution
As absurd as this sounds, our deplorable fatal accident rate IS caused by the freedoms we GA pilots enjoy to come and go as we please in our airplanes. We have no supervisory oversight as is found in Part 121 and 135 operations. We are exempt from regulatory takeoff minimums, and we can shoot our instrument approaches regardless of the reported weather, again unlike our airline and corporate brethren. We can stick up our noses at any notion of recurrent training. And we can shop around until we eventually find a friendly CFI to pencil in a required flight review in our logbooks. These are freedoms endowed to us as Americans. Never piloted an airplane before? Sign up for just 20 hours of flight instruction and you can command a light sport, two seat airplane high over big cities. Health issues? No problem . . . if you can drive a car, you're good to go in light sport. Is this bad? No, this is not bad. Our freedoms were bought and paid for by our nation's veterans. These freedoms include our right to operate privately owned airplanes. As long as we do this safely and responsibly, our freedom to fly will remain intact. But when we abuse this privilege through incapacity, oversight, or neglect, society will place serious restrictions on our freedom to fly. Surprising to many, we are only a hair-trigger away from wholesale restrictions on general aviation. Let one of our five daily crashes take out a packed elementary school, a busy shopping mall, or a government office building, watch the hammer fall! In-flight collision with airliner? Whoa! Not even AOPA's Phil Boyer and his powerful political weapons can save the day for GA. Alarmist point of view? Watch and wait! So who IS to blame?
I've heard from a reliable industry insider that if you packed representatives from each of these industry components into one big room, nobody would accept any responsibility for our deplorable fatal accident rate. Worse, all of the king's men and all of the king's horses couldn't find a way to put Humpty Dumpty back together again. So where does this leave us? Where does this leave us? It leaves YOU and ME to accept responsibility for our own actions in an airplane. It is up to each of us to secure meaningful initial and recurrent training, to gain worthwhile aviation experience, and to arrive at our destination unscathed. If enough of us do this and, through our example, we can persuade the remainder of the GA community to become and remain flight proficient and current, the great risks facing general aviation will begin to diminish, our insurance rates will decline, the public's perception of general aviation will improve, our pilot numbers will eventually increase, and the economic health of our industry will soar. Who's to blame? You and I are.
As we do this, our land-based navigational proficiency begins to slip to a dangerously low level. I see this every time I train with pilots of GPS equipped airplanes. How many of us will be able to comply with the following holding instructions? "Nxxxx, hold east on the Buffalo 080 radial, 20 DME fix, three mile legs, standard turns, expect further clearance at 2010, time now 1940."
Sure, our growing dependency on GPS is still too new that most of us can conjure up a basic recollection of VOR navigation. We can still find our location by triangulating between two VORs, but those skills are quickly becoming atrophied. So, what's the problem? The problem is, ATC still depends upon VORs, VOR radials, and published airways to maintain their desired traffic flows. For those of us who fly around the big eastern seaboard airports, beware! Case in point I recently departed the Atlantic City, NJ airport (KACY) on a flight back to Buffalo. Having two Garmin 430s in my T-210, I filed a simple two leg routing to bring me around (not through) the busy Philadelphia Class B airspace. The routing I filed read as follows: "DQO (Dupont VOR) direct." The "approved" routing read back to me by KACY clearance delivery read as follows:
Does this sound like a simple GPS-Direct routing? Of course not. This routing was likely crafted by ATC traffic specialists back in 1972 and has been used ever since to direct Atlantic City traffic northward around Philadelphia. The fact that I was GPS equipped and filing ". . . /G" had little impact on the routing ATC actually gave me.
It also required tuning the old-fashion VOR radios and twisting of omni bearing selectors (OBS) to capture the VOR radials referenced in my clearance. It gets worse! Just in case you think that this routing was the final word on the subject, here is an amendment to this routing I received during my climb out from KACY:
I have no clue as to what necessitated this re-routing, but it escalated my workload dramatically. I took another look at the low altitude enroute charts, found the new fixes and airways, and re-programmed the GPS, all while still in the climb. Yes, Virginia, single pilot IFR requires consummate proficiency. Wake up . . . Smell the Coffee
Solution The solution to our cockpit technology explosion is to turn off the new stuff every so often. Rather than filing GPS-direct, file ". . . /A" and navigate the old way. Exercising the past is a very good way to remain proficient in the future! Lastly, do not fall into the mistaken belief that having enroute and approach certified GPS or a fancy new glass panel equipped airplane makes it possible to file direct to anywhere you wish to go. Yes, you can expect to go direct in those big open spaces, but certainly not in and around busy airspace.
And, as good friends, we need to talk with them . . . at specific points along our route of flight. Naturally, we respond each time we hear them calling our tail number. We also call them when we have a particular request. Lastly, there are several times when a call to them is compulsory. Do you remember when these times are? If you are an instrument student, you had better know these times for your oral!
Also as good friends, air traffic controllers can be counted on to help us out of tough situations. Often regarded as a second or third member of the flight deck crew, controllers hold the keys to such things as: (1) better weather; (2) smoother rides; (3) short cuts and direct routings; and (4) other traffic. While their sole primary responsibility is traffic separation, sweet talking an air traffic controller can work wonders in our national airspace system. In fact, the way we talk with them can make the difference between a timely vector to the final approach course versus a very long vector around Nova Scotia. Let's be sure to do our jobs in the communications department. Know those compulsory calls.

So what is the cautious pilot supposed to do? We have three choices.
Sadly, the accident data reveals that far too many of us
select option #1. We launch in the face of gusting
crosswinds only to find ourselves drifting helplessly across the
runway, taking a handful of runway lights with us.
Mashing the brakes
We emerge from the cockpit unhurt but with a bent airplane and a seriously damaged ego. Our mishap becomes the topic of endless hangar conversations for miles around. Fearing option #1, an equally large number of us toss in the towel anytime the winds are blowing 15 knots or more across the runway. A wise decision but this option substantially reduces the utility of our airplane. It is also a great disappointment to passengers hoping to go someplace that particular day. Choice #3 is the place to be! Picture the following scenario. You're visiting your wife's family 350 miles from your home airport. Contrary to forecasts, the winds have kicked up a bit. Nothing serious, but gusts are blowing 45 degrees across the runway at 14 knots with gusts to 18. It's late afternoon and you definitely need to be back to work in the morning and your accompanying teens can't miss another day of school.
Answer: You opt for choice #2, call the boss, then write a note to your kid's teachers. The only happy person is your wife . . . she gets to spend another night with Mom and Dad. Upon returning home three days later (it was slow moving front that caused the winds), you call your friendly CFI and begin the process of mastering crosswind operations! "George . . . I've got to master crosswind landings and takeoffs. Can you help me?" George agrees, then you both begin waiting patiently for a windy day with gusty crosswinds. When that day comes, you both drop what you are doing and rush out to the airport. You pull out your airplane, pre-flight, then taxi over to the least favorable runway wind-wise. With 18 knot direct crosswinds (and gusts up to 25 knots) from the left, you line up on the runway. You roll your yoke or stick to the left stop, then you apply full power and begin your takeoff roll. You rotate and begin an immediately bank into the wind. You apply enough opposite (right) rudder to maintain your track over the runway. Once clear of any obstacles, you level the wings and apply the rudder inputs necessary to keep the inclinometer ball center (see graphic below).
Mastering crosswind takeoffs and landings requires proper instruction and lots of practice . . . lots and lots of practice. Once accomplished, you will begin to maximize the utility of your airplane. Flight students: If your flight school or flight instructor refuses to fly when the surface winds approach 15 to 25 knots, do yourself a great big favor and find another source of instruction!

The previous OTA issue contained a brief story of a local chief flight instructor on a training flight who attempted to take off on a closed runway. This story generated a host of reader responses describing similar dumb CFI moves. None of us is perfect and we CFIs, like other mere mortals, are subject to the same human frailties that lead to dangerous oversights and omissions in the cockpit. Nonetheless, one would expect a higher standard of performance by those entrusted with the lives of people learning how to fly. So what is the problem here? The problem here can be traced directly back to FAR 61.183(j) which sets the experience requirements to become a certificate flight instructor. Caution: You may require smelling salts to revive you after reading this section of the regulations.
Yep . . . log 15 hours as pilot in command and you, too, meet the minimum flight experience to become certificated flight instructor in the airplane of your choice. Remember, of course, that part of your job description will be to impart the necessary aeronautical decision making (ADM) and risk management skills to insure the safety of pilots entrusted to your training! Of course, you need to meet the PIC requirement for your private pilot certificates (10 hours) and the commercial certificate (250 hours). But if you back out all of the dual training requirements required for your various ratings (instrument, multi, etc.), you could manage to qualify as a flight instructor with only a handful of actual solo hours! And most of these solo hours were likely earned in some fair weather practice area near the airport. So where does the lifesaving pilot wisdom come from? Where is the wisdom? Sadly, it is not there in many of our flight training establishments throughout the United States. Flight schools routinely use last year's flight students as this year's flight instructors. These folks want the flying hours and they work cheap. Worse, many of these same fledgling pilot/instructors train up future flight instructors out of the same ranks of pilots who sat beside them in ground school. This system of creating flight instructors has been with us since 1941. So what's the problem? The problem? The problem is, the world in which we fly has changed dramatically in just the past five years.
In just a few more months, this same neophyte pilot with minimal training from an equally inept CFI will be blasting up into the flight levels at over 300 knots in a VLJ (very light jet). Okay, so he will require a type rating, but type ratings do not cover basic stick, rudder, and navigational skills Five years ago, this same pilot would never venture into and around seriously deteriorating weather simply because he lacked the uplinked weather information necessary to navigate around the worst stuff. Not so today. Today, this low time private pilot has just enough information being displayed on his multi-function display to kill him. A little over five years ago, this neophyte pilot would not have to concern himself about jet fighter intercept procedures. He could fly pretty much anywhere his J-3 Cub could take him. Yes, Virginia, the world has changed, but the flight training community has not.
One simply needs to read the Notice of Proposed Rule Making (NPRM) record of testimony pertaining to any of the FAA's many of proposed flight training and/or pilot qualification changes to the FARs. You'll wonder if those same big GA membership organizations are on the same side of the flight safety fence as we pilots are. Okay . . . so some of these FAA proposed changes came from Mars. Agreed, such inept changes to the regs need to be stopped before they see the light of day. But, for the most part, the FAA does have a pretty good handle of this very problem - specifically using neophyte pilots as CFIs to train other pilots. This practice MUST come to a stop. So where do these young pilots obtain the flight experience to become wisdom-filled flight instructors?
What should we be doing? It is a cinch that we cannot do much about changing the FARs governing the experience requirements to become a CFI. But we can do something about our own training and the training being received by our friends.
It is not Over the Airwaves' intent to bash inexperienced flight instructors. We all had to get started somewhere. But remember, it is YOUR life and the lives of your friends that count. This is not golf, bowling, or tennis we're talking about here!
Digging deeper into the problem of faulty or defective instruction, the ultimate source of the problem is the Practical Test Standards (PTS). Actually, it is not the PTS but the manner in which the PTS is being used. Learning versus Passing the Test!!!
This "teaching to the test" process is reinforced by the publishers of FAA knowledge test Q and As, free on-line practice test sites, and printed oral prep guides. Similarly, CFIs and the flight schools are notorious for drilling flight students to compliance with the minimum standards for each proficiency element contained in the PTS. Endless hours are spent in the local practice area or, worse, in the simulator. In turn, students expend enormous energy trying to memorize answers and procedures. Enter the Discriminating Pilot Examiner!
A great crisis quickly surfaces as the nervous student confronts, for the very first time, a person who is less interested in PTS compliance and is more interested in what the student actually knows and is able to demonstrate. "Can this guy fly from "A" to "B" without killing himself and others?" This crisis escalates the moment the student recognizes that his or her level of actual aeronautical knowledge and skills are far below what the pilot examiner is looking for. He tries in vain to spit out memorized answers to stock oral questions. But just as soon as the examiner begins to probe deeper, the student suffers an instant brain fart. The same thing happens during the practical test. The examiner steps outside the comfortable boundaries of the PTS for a moment to assess the depths of the student's actual flying skills. The examiner quickly discovers a hollow shell of inability. The automaton skills imparted by his hapless CFI leave the student unprepared for even the most rudimentary non-PTS related exercise. Yes Virginia, there is a solution!
Student pilots have a choice. They can memorize the answers, fly the PTS elements ad nauseum, spend hard-earned money sitting in the make-believe world of GA simulator while their instructor sips coffee, and practice calm-wind landings at the same airports over and over. Or . . . they can go get into the system midst the fire and fury of real world flying where crosswind landings are the rule rather than the exception. They can choose to sit next to experienced CFIs who impart wisdom, aeronautical decision making skills, and principles of risk management enroute to distant cities instead of endless hours in the practice area. In summary, students who fail checkrides are typically those who are unable to demonstrate sufficient proficiency to remain safe in today's highly sophisticated national airspace system. In short, there is far more to safe flight than nailing turns on a point or keeping the needles centered on the ILS.

It was a blustery morning last Thanksgiving weekend.
A low time, VFR only pilot and two friends took off from Centennial
Airport (APA), near Denver, Colorado in a Piper Cherokee.
Their destination was Morris, Illinois.
Low overcast clouds necessitated a hazardous scud-run. Anybody familiar with this route of flight knows that the terrain is as flat as a pool table (first link in the accident chain). According to the NTSB Report, the pilot held a private pilot certificate with a single-engine land rating issued on August 26, 2002. The pilot held a third-class medical certificate with no limitations dated May 3, 2005. The pilot recorded that he had accumulated 409 hours of total flight time and 33 hours of flight time 90 days in his logbook. The endorsement for his last flight review was dated January 8, 2005. Witness statements: -- Passing motorist "I observed that approx. the top
100-125 feet of the tower was in the The Crash Scene
When the struck the tower it collapsed onto itself and the station's roof. The airplane fuselage was found about one tenth of a mile from the base of the antenna on a 101-degree magnetic heading. The wings had separated from the fuselage in a debris field that, measured from the antenna base, extended southward about three tenths of a mile on about a 171 degree heading. Probable Cause Determination The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
This is a simple case of aeronautical decision making (ADM) gone wrong. This pilot was embarking upon an over seven hour flight in marginal VFR to IFR conditions. He apparently elected to scud run over unfamiliar territory. This fatal scenario gets repeated week after week. Believing that one can keep a constant vigilance in declining weather for long periods of time is a cruel and deceptive self-hoax. Solution
Remember, however, to check NOTAMs carefully. Tall towers go up everyday. Given the affordability of terrain awareness technology (Garmin 296, 396, 496 portable GPS), all VFR pilots should make use of this safety resource. A long term solution for this pilot would have been to secure his instrument rating and demonstrated instrument proficiency before commencing this long cross-country trip. VFR-only long cross-country trips, can be an invitation to disaster unless such pilots have the enroute discipline to get and remain on the ground until ideal VFR weather returns.
John Jesson, (photo middle), manager of the Akron, NY Airport (9G3), said 30 years ago, "Nobody believed this airport would ever survive!" But it did, and much of the credit goes to the faith and efforts of John and his wife, Nancy (photo left). They and their partners, Dave Gray (photo right), Larry Cummings, Liz Zaky, and a host of other volunteers turned this dilapidated, weed infested airstrip into one of New York State's premier general aviation airports. Operating under the corporate title of Christian Airmen, Inc., these individuals, 30 years ago, set forth on a mission to show by example and through the grace of God how seemingly impossible obstacles can be overcome to create an airport masterpiece. Congratulations, John and Nancy. You are, indeed, good and faithful servants!
It looked like a normal training flight
last November at the Leesburg Regional Airport in Northern
Virginia. A flight instructor and student were practicing
touch and go landings in a Piper Warrior. The weather was
fine.The first indication of a problem was noted when the airplane apparently failed to climb after touching down. Witnesses saw the airplane roll along the entire length of the runway before becoming airborne. Then, within seconds, other witnesses saw the airplane suddenly roll over near vertical before it crashed nose down not far from the runway. Okay . . . another stall/spin accident (they happen every week in the U.S.) Another classic stall/spin accident, right? But wait . . . let's take a look at the post-crash toxicology of both the flight instructor and the student. Let's see what they found in the blood and tissues. First the flight instructor:
Yep . . . good old marihuana! They found enough of this stuff in the CFI's lungs, blood, and urine to register in the toxicology tests. While it is unknown what effect this concentration of marihuana had on the CFI's performance, clearly the outcome of this routine flight exercise suggests that something abnormal was happening. Next the flight student:
Hmmm . . . the NTSB Report tells us that these items are a sedating over-the-counter antihistamine and a prescription antidepressant. While it would properly require an aeromedical pathologist with a PhD in psychopharmacological chemistry to assess the potential impact of these drugs on pilot performance, we might reasonably assume these guys were functioning somewhat less then "normal." There are no secrets
Quite naturally, crashes like this that occurred at Leesburg, results in bad press, negative public perception of GA, and higher insurance premiums. If EVER we observe such behavior taking place, we pilots have a sacred obligation to take steps to prevent it from turning into a tragedy. Whether it is alcohol on one's breath or knowledge that some hapless pilot is being medicated for emotional problems, stepping in boldly and preventing his flight could save a life as well as another black eye for general aviation.
The flight instructor explains that removal of 50 percent of the vertical component of lift explains why this altitude loss occurs. The CFI also explains the airplane's natural tendency to roll beyond the stipulated 45 degree bank angle. This reason is illustrated in the accompanying graphic (right). What happens when the pilot is caught unawares? Somatographic illusions are those sensations that "trick" our bodies into believing we are in one flight attitude when, in fact, we are in another. Returning to level flight after a long, slow turn, for example, causes the fluid in the semi-circular canals of our inner ear to begin flowing in the opposition direction. This, in turn, can give us a serious case of the "leans." Suffering the "leans," we think we're turning, but we're not. Disbelieving or ignoring our bank and turn instruments showing straight and level flight, we make control inputs that inadvertently place us in a bank. Now for the insidious part
We learned from those long, boring trimming exercises that as the airspeed increases, the airplane wants to pitch up. The problem is, the airplane in this scenario is not in a wings level flight attitude. Instead, it is banked, so UP is really no longer up in relation to the ground. Instead, UP is sideways. Thus, this pitching UP moment is actually pulling the airplane into an ever-tightening bank angle. As this bank angle tightens, any remaining vertical component of lift is lost. The nose drops to a near straight-down pitch attitude. Again, airspeed increases as the full force of gravity coupled with the down-pointed trust of the engine pulls the airplane into an even tighter spiral.
Instinctively, he pulls back on the yoke in a vain attempt to arrest the descent rate. This action, of course, pulls the airplane into the last few degrees of a tight fisted spiral. Equally disastrous, he may even roll the wings level. If he does this without an aggressive push on the yoke, the airplane will likely pitch up with such force that its structural G loading limit will be exceeded and its wings will separate from the fuselage.
Recollection of the infamous JFK, Jr. crash Below is an extract from the JFK, Jr NTSB Report. This is a description of a classic graveyard spiral:
In summary, traditional flight training doctrine suggests that the best way to handle a graveyard spiral scenario is not to allow one to develop - duh! Unfortunately, far too much of today's instrument training, including instrument proficiency checks, is being provided in GA flight simulators. While sufficient to develop instrument procedure skills, stationary simulators fail to simulate any of the spatial disorientation factors that can lead to the fatal graveyard spiral. Similarly, the use of view limiting devices to simulate real IFR conditions are equally unreliable. The only effective way to experience the conditions leading to insidious IFR upsets including graveyard spirals is to get into REAL IFR conditions with a skilled and experienced CFII aboard.
Whenever I see this scene, I long for the opportunity to get this self-proclaimed ace of the base into my trainer for a couple turns around the patch and an hour or two in the classroom! I guarantee that some of these guys could not pass the private pilot checkride. How about the oral exam? No way! Just as age is no predictor of pilot skill, logbook hours can be just as deceiving. The pilot who has stopped learning is a dangerous person. You do not see these people at safety seminars. There are no aviation periodicals in their mail. I don't risk offending them because they are certainly not reading Over the Airwaves. The truly proficient pilot, on the other hand, is one who, like Captain Jeffries (quote above), recognizes that learning is a life-long process. He understands that repetition is the price of learning. Performing the same drills, over and over, help to retain skills. Reading and listening help to fill the gaps of what we've forgotten or never learned in the first place. When we examine why GA pilots turn their airplanes into lawn darts and leave smoking holes in the ground once a day in the United States, we often see evidence of this arrogance. Skipped pre-flight briefings and blasting off into dangerous weather are examples of this behavior. Looking deeper, we find little or no evidence of meaningful recurrent training. We see little or no participation in pilot self-improvement programs. Instead, they rely upon a hyper-normal self-esteem and the ignorant belief that what they learned years ago will keep them safe today. Yes . . . we still record over 1,500 serious accidents a year, of which more than 300 involve fatalities. Most notably, nearly 80 percent of these are caused by pilot error. While some of these tragedies can be attributed to inexperience, the vast majority can be attributed to one pilot characteristic . . . arrogance!
