Dear Pilots and Aviation Enthusiasts:
One of the most awesome responsibilities we face as parents occurs that first time we hand our teenage son or daughter the keys to the family car. We birthed them, fed them, nurtured them, and educated them. Now it is time to launch them on to the nation's highways in two ton vehicles capable of traveling over 100 miles per hour. We pray that they know what they are doing, that they have the required judgment, and the wisdom to obey the traffic rules. In most cases, fortunately, everything works out fine. And the reason it works out fine is, frankly, because of we parents. We performed our jobs properly . . . and our teenage kids did likewise. We flight instructors face similarly awesome responsibilities when we sign off a student pilot for that first solo flight. We showed them how to pre-flight the airplane, how fire-up and taxi across the airport, how to perform basic flight maneuvers, then how to land safely. We nurtured them from walking on land to taking up wings and soaring like the eagle! And, as in teaching teens how to drive, everything works out fine . . . most of the time. Why, then, do things go wrong? There is nothing more tragic than learning of a horrible crash of a car full of teenagers. A young driver, with little or no real world experience, rounds an icy curve too fast for road conditions. He skids off the roadway, down a ditch, and overturns with unspeakable consequences. Parents search their hearts and heads for an explanation why their four teenagers died. Similarly, there is equally nothing more tragic than learning of a family of four who, while flying in poor visibility weather, crashed with no survivors. Friends, relatives, the public . . . and the NTSB wonder what went wrong. Let's look at the parallels between these two tragic crashes. In the car crash, the teenager was driving too fast for road conditions. In the airplane crash, the pilot was flying in weather conditions more challenging than he was capable of handling. In both cases, lives were lost due to skill deficiencies of the operators. Icy Roads Happen . . . Poor Flying Weather Happens! It is easy for parents to tell their teenagers not to drive on icy roads. On the other hand, it requires a special effort on our part to actually take our teenagers out on icy roads and demonstrate to them safe operating speeds and how to recover from a skid. Which would be a more effective approach in the long run? Saying "no" to driving on icy roads, or taking them out for icy road training? Saying "no" did not help that car full of teenagers! Many flight schools, independent flight instructors and yes, even some in the FAA, address the problem of poor flying weather by telling pilots NO! They tell them to remain on the ground. Good advice? Yes. Practical . . . not really! Like icy roads in Upstate New York from December through March, poor flying weather can occur just about anytime and anywhere. What starts off to be predictably good weather occasionally deteriorates despite "official" forecasts to the contrary. What is forecast to be greater than three miles visibility suddenly becomes less than one mile . . . particularly when flying into a rising or setting sun. What should have been nine knot winds directly down the runway at our destination becomes fifteen knots with gusts to twenty directly across the runway! It is a privilege to fly, but it is also a responsibility to know how to deal with the surprises! It is time that we pilots confront reality. "Stuff" happens. Self-denial and/or refusal to train for this "stuff" is the number one reason why 75% of all general aviation accidents are due to pilot error. But just as we would not send our teenage drivers off to practice driving on icy curves in the road by themselves, we should not be going off by ourselves to practice in poor weather. Instead, we should be securing the best instructional resources available. Then . . . armed with appropriate professional talent along side us in our cockpit, we should go out and learn how to deal with the "stuff." CFIs beware! Just because you are a flight instructor does not make you automatically qualified to teach in uniquely challenging weather. Be sure you are proficient before engaging students! Winter is rapidly approaching here in Buffalo, NY. I have a daughter turning 16 this winter. Guess what she and I will be doing! You guessed it! We're going to be doing scenario-based training in the car . . . just like we pilots should be doing in airplanes!
It is not as if the first few solo hours are not anxiety producing enough. Imagine throwing in a "for real" engine failure with just 2.5 hours total solo time to see how you perform! Seems that is just what happened to OTA reader and pilot Sally Kilshaw of Saratoga Springs, NY. Sally had logged just 2.5 hours solo flight as a student in her Cessna 152 when a piston rod blew through the engine case causing causing sudden engine failure with smoke and oil spewing all over the windscreen. Fortunately Sally's flight instructor, who happened to be her husband Alan, insisted that her pre-solo training incorporate extensive emergency procedures . . . including engine failures and fires.
With engine shaking violently, Sally managed to locate a suitable emergency landing site. She maneuvered her "dead stick" aircraft to the ground just as she had trained many times before. She admits that the landing wasn't pretty, but she walked away with minor bruises and a cut lip. The engine and airplane were a total loss. Anxious to solo too soon . . . Everybody wants to solo just as soon as they can reliably land the airplane. This is fine as long as the student is able to deal with situations like that experienced by Sally on this fateful day. It is a wise and prudent flight instructor to hold off that first solo until he is sure that his protégé can handle any possible in flight emergency. Congratulations to Sally . . . and an even bigger "attaboy" to her instructor (and husband), Alan, who saved the day by providing excellent pre-solo flight instruction! Emergency procedures should be practiced often by every pilot! An engine fire or failure, a jammed control surface, or a serious upset can occur at any phase of flight . . . and they happen when we least expect them. Rather than being caught like a deer in the headlights, proficient pilots act immediately and they act appropriately. Begin by having an effective checklist for each kind of emergency. Know where that check list is and how to reach it in a hurry (and in the dark)! Build your inventory of "back doors." If you cross large bodies of water, carry a raft and life jackets. ALWAYS have a fire extinguisher close at hand in the cockpit. Put a handheld radio in your flight bag with extra batteries. Create a survival kit to have in the unlikely event of an emergency wilderness landing . . . and consider including a firearm. One of the best emergency precautions is . . . an expert aircraft mechanic. These guys (or girls) are worth every dollar you pay them. I have two mechanics in whose hands I place my life almost every day of the year. One is Kirby McCall, A&P, AI at the Dunkirk Airport, Dunkirk, NY. He and his staff are the personal physicians to my T-210. The other is Kevin Rose, A&P, AI at the Akron, NY Airport. He provides expert maintenance to the rental fleet I use in flight training. Each of these gentlemen are among the best in the business. Your other emergency precaution is . . . your flight instructor. If he or she is good, you can count on being prepared for the worst possible disaster. If they are not - start shopping around TODAY! The best accident prevention resource is . . . you! If you are proficient, nearly all emergencies quickly become non-events.
Here's the scenario. You take off in a well-equipped, high performance airplane. All that stands between you and your destination 200 miles to the east is a series of jagged mountain ridges extending upward between 7000' and 8,000' MSL.
This is a classic risk management scenario. If you file an IFR plan and climb up into freezing clouds well above the mountain tops you MAY encounter airframe icing. On the other hand, if you decide to remain VFR and fly between the mountain tops and the lowering ragged clouds above, you run the risk of being "squeezed" into rising terrain. You could, of course, remain on the ground and wait for better weather. This scenario is very real for me. I faced similar circumstances on each of the last two ferry/flight training flights I made from the west coast to the east coast. So what do you do? Okay . . . who among you selected the "remain on the ground and wait for better weather" option? Be careful. That may not be the best answer!!!!!!! Take a closer look at the above photo of the mountains and clouds. It illustrates the favorable weather conditions for a trip over rising terrain and peaks to your destination. You decide to launch VFR. Enroute, however, the actual weather conditions are somewhat worse than forecast. It's still acceptable for a safe transition, so you proceed, confident that everything will work out okay. Thirty minutes later, with peaks in front and behind, you begin to feel a little bit uncomfortable. The broken skies above are now overcast. The outside temperature at your altitude is -8C. You drop a bit lower to remain VFR. Suddenly, several of the surrounding peaks are obscured by the lowering clouds and declining visibility. What do you do now?
No fair claiming that the pilot should not have gotten caught in this predicament! Recall, he had a favorable weather briefing before starting out. Unfortunately, the forecast was wrong! More scenario information: The airplane has no anti-icing capability other than pitot heat. It has no terrain avoidance technology.
Looking at the relative risks of each, there's no question in my mind that he must secure an IFR clearance and climb. In fact, given the described circumstances, he might consider declaring an emergency and immediately climb with or without an IFR clearance. Remember, we are assessing risks here. In all probability, impacting mountainous terrain will likely be fatal. Climbing into icy clouds, on the other hand, may not pose a serious icing risk. Recall that not all freezing clouds contain ice. Given the capability airplane, even if moderate icing were encountered, there is a good possibility that it could climb through the icing layer and even find VFR above. Is this the correct answer? Regrettably, there is no "correct" answer. This is why scenario-based training coupled with aeronautical decision making and risk assessment is such a complicated subject. What works in one instance may not work in another, and there certainly is no "one size fits all" solution as is often proposed in the FARs. If this were me in the above scenario, I'd choose to take my chances with the icing layers above rather than play Russian roulette with the terrain below. Not everybody would make this choice, but given the factors in this scenario, climbing is the far more prudent option, in my opinion. Yes . . . there will be some who would elect to remain on the ground until a perfect weather picture presents itself. But the real world doesn't work that way. If it did, few of us would own airplanes and most people would still be taking trains!
One of the strangest paradoxes in aviation can be observed when a timid student pilot who otherwise spends hours on the cell phone is instructed to push the aircraft microphone button and talk. In this instant, cold sweat can be seen beading up on their forehead. Their voice trembles as they begin to utter those first stammering words. "Ahhh, Anytown tower, this is Bugmasher 3434. I wanna, ahhh, land right now, please!" At that moment, the student pilot would like to be just about any other place in the world than in the left seat of an aircraft in flight. Fearing that the entire world is listening, they suffer pangs of anxiety that are normally reserved death row convicts as they are strapped into the electric chair! What causes mike fright? I've asked myself this question every time I have sat next to a "micro-phobic" flight student. In most cases, I believe it comes simply from not knowing what to say or in what order to say it. This problem can be solved by understanding that every microphone exchange between pilot and controller follows a standard pattern. If you know the pattern, the mike fright goes away.
Who you're calling . . . who you are . . . where you are . . . what do you want to do! For example: "Buffalo Approach, Skyhawk 2344Y, just off Anytown Airport, going to the north practice area." or "Anytown tower, Skyhawk 2344Y, 8 miles west with information Sierra, inbound for landing." Sometimes you want to do something a bit more involved or complicated. Instead of spewing out your intentions in one long message, simply use the word "Request." For example: "Anytown tower, Skyhawk 2344Y, 9 miles east with information Tango, Request." When the tower replies, tell them your request. "Anytown tower, Skyhawk 2344Y would like to touch and go on Runway 5 and then remain in your pattern for multiple touch and goes." See the communications pattern? Who you're calling . . . who you are . . . where you are . . . what do you want to do!
Put the microphone close to your lips and speak UP! Controllers are busy folks and sometimes the noise of other controllers talking in the background hinders their ability to hear you. So speak up!!!!!! Speak slowly! Don't try to emulate professional air traffic controllers who are skilled at speaking 300 to 600 words per minute. Air time is precious, but not at the expense of garbling your words. Avoid the use of extraneous, unnecessary words! Phrases like "with you" or "this is" tie up the airwaves. Give them just the facts. For example, when handed off to the next controller, say: "Rochester Approach, (omit: this is) Bugmasher 1235Y, (omit: with you at) 4,500 feet." Air Traffic Controllers are nice people! They really are. They are also trained to assist rather than to complicate the pilot's life. If you do not understand a controller's instruction, simple reply, "Say again." They will repeat it as often as necessary until you acknowledge your understanding! Aviate, Navigate, then Communicate! While important, talking on the radio is the last of three important piloting priorities. First, fly the airplane, next remain on your desired course, then . . . and only then . . . talk on the radio. Unless the controller is issuing you an urgent terrain or collision alert, talk on the radio only when you can safely do so. Two Important Words: "Unable" and "Stand by" - Never be afraid to put the controller "on hold" if he calls you at a bad time. If you cannot comply with a controller's request, say "Unable." He or she will offer you another option. If you are too busy to answer the controller, simple say, "Stand by." Then get back to him when you are able. Words to eliminate from your radio transmissions . . . We all want to sound like professionals on the radio. We can do this through common sense phraseology. For example, here is a list of sure-fire words and phrases that will quickly identify you as an amateur pilot:
Helpful advice to flight instructors: Mike fright is a real fear and should be treated as such. When combined with the other associated fears of flight, unresolved mike fright can cause a new student to quit training altogether. If you suspect that your student is experiencing mike fright, save this element of training until later in your curriculum. You will be surprised how quickly your mike frightened student will become a good aviation communicator AFTER those other fears of flight are resolved!
Rather than applying power and going around, he elected to chop the power, raise the flaps in hopes of improving tire traction, then ran off the end of the runway and flipped over. The temptation to salvage a bad approach and landing can be more than many pilots can handle. These pilots develop a mindset that they are going to get in and land no matter what! The proficient pilot is always ready for a go around! The actual act of landing and coming to a safe stop is viewed by the proficient pilot as the reward for doing things right. He or she figures that any number of things can go wrong in the landing process . . . too high or fast on the approach, a long float over the runway, a ballooned or bounced landing. Any of these unstabilized conditions are sufficient justification to add power and go around. Unless you are out of fuel, on fire, evading a thunderstorm, or crippled up with ice, never try to salvage a bad landing! Going around for another try is the safest thing to do. Had our accident pilot done this, things would have likely turned out much better!
Yes, of course, holding patterns still exist and are sometimes even used, but thanks to improved radar coverage, flow control, better weather forecasting and detection, and other ATC vectoring tricks, banishment to a holding pattern is rapidly going the way of the non-directional beacon. But guess whose keeping us on our toes? Yep . . . your friendly Designated Pilot Examiner (DPE) when conducting an instrument check ride. Also, per FAR 61.57(c)(1), we instrument pilots must either experience or practice holds every six months to maintain our instrument currency. So if we must practice them, let's practice them correctly! Recall the anatomy of a holding pattern.
Holding patterns begin and end at a specific point called the holding fix. Everything else is oriented on that fix. Review the illustration to the left.
How we maneuver into a holding pattern . . . Believe it or not, nobody other than your Designated Pilot Examiner (DPE) and perhaps your flight instructor really cares how you get yourself into a holding pattern. When ATC assigns or clears you into a hold, they expect you to go to your assigned holding fix, to maintain your assigned altitude, and to remain in the hold until cleared to depart. That's about it. So what is this noise about types of holding entries? Honestly, I don't know! But here's what the book says . . . (and we wonder why people grow frustrated with instrument training!)
1. Parallel procedure: When
approaching the holding fix from anywhere in sector (a),
turn to a heading to parallel the holding course outbound on
the nonholding side for approximately 1 minute, turn in the
direction of the holding pattern through more than 180°, and
return to 2. Teardrop procedure: When approaching the holding fix from anywhere in sector (b), fly to the fix, turn outbound using course guidance when available, or to a heading for a 30° teardrop entry within the pattern (on the holding side) for approximately 1 minute, then turn in the direction of the holding pattern to intercept the inbound holding course. 3. Direct entry procedure: When approaching the holding fix from anywhere in sector (c), fly directly to the fix and turn to follow the holding pattern. A couple of more things we need to know about holding patterns . . . Pilots should make all turns during entry and while holding at:
Here's what Paul Berge, retired air traffic controller and former editor of IFR Magazine has to say about entering holding patterns:

It may come as a surprise to those new to aviation that most piston airplane engines are more similar to our lawnmower engines than they are to our automobile engines. Rather than employing an elaborate electrical system like that found in an automobile engine to create a spark to ignite the fuel/air mixture, our airplane engines use a simple little device called a magneto . . . actually two identical magnetos for redundancy-sake. It is the same device found on lawnmowers. Here's how a magneto works . . . An aircraft magneto is driven mechanically by the engine. It changes mechanical energy into electrical energy. Operating on the principle of electromagnetic induction, the magneto generates its own primary current and therefore needs no outside source of electrical power such as a battery or generator/alternator. The magneto generates its own low voltage current to energize the ignition coil, which is inside the magneto. The magneto’s ignition coil transforms (by electromagnetic induction) the low voltage current to high voltage current. The distributor
in the magneto picks up the high voltage current from the
coil and delivers it through the coil to the spark plugs at
the proper time to ignite the fuel-air mixture in the engine
combustion chamber. The delivery of current to each spark
plug is timed according to the firing order of the engine. Switch on the mags, pull on the prop, the engine starts! Just as you pull on the rope to start your lawnmower engine, you simply give a tug on your propeller to start your airplane engine. It is the manual turning over of the engine that causes the mags to perform their electricity making job. Once the engine fires, the mags continue to make "spark-giving" electricity. It can't get much simpler than that! Well . . . it is a bit more complex than that - but too not much!
The typical aircraft ignition key has five positions: (1) off; (2) right mag; (3) left mag; (4) both mags; and (5) starter motor. Turning the key all the way to the right or 5th position causes the starter motor to engage. Releasing the key causes it to drop back to the "both mag" or 4th position. A magneto uses a permanent magnet to
generate an electrical current completely independent of the
aircraft’s electrical system. The magneto generates
sufficiently high voltage to jump a spark across the spark
plug gap in each cylinder. The system begins to fire
when you engage the starter and the crankshaft begins to
turn. It continues to operate whenever the crankshaft is
rotating. Each magneto operates independently to fire one of the two spark plugs in each cylinder. The firing of two spark plugs improves combustion of the fuel/air mixture and results in a slightly higher power output. If one of the magnetos fails, the other is unaffected. The engine will continue to operate normally, although you can expect a slight decrease in engine power. The same is true if one of the two spark plugs in a cylinder fails. The pre-flight mag check. What does it tell us?
Watch those weak magneto rotor magnets: If you are experiencing chronic hard engine starts despite proper magneto care, consider the possibility of a weak magneto rotor magnet. During start the impulse coupling snaps the magneto to a high speed and produces a spark even with a weak magneto. In cold weather the starter turns the Continental or Lycoming engine slower and the engine accelerates slower because of the cold, thick oil. The engine fires, but fails to start because after the impulse snaps, the magneto must produce a spark at near cranking speed to accelerate the engine. If the magneto can't produce a spark at this low cranking speed the engine fires but quits. A normal magneto should have enough rotor magnetism to spark the plug at 150 rpm so that the engine not only fires but continues to run. If the aircraft magneto's rotor magnets are weak, the engine has to turn faster before enough energy is produced to spark the plug. Magneto rotor magnets may have lost much of their strength. The magnets are typically not restored to full strength at overhaul because of the high cost of magnetizing equipment. For more information on magnetos, click HERE.
Do you want to know the two words most
frequently spoken by a proficient pilot when making a the
final
approach to landing? They are (or should be)
"Airspeed ~ Runway." That's because it is
the
airspeed indicator and the location of the runway that
should be the PRIMARY things he or she should be attending
to during this most
This was apparently not the case for a Cherokee Six pilot performing touch 'n goes in Venice, Florida in May, 2004. NTSB Probable Cause Finding: "Failure of the pilot to recover from an improper landing flare resulting in his failure to maintain airspeed (Vs), an inadvertent stall, loss of control, and in-flight collision with terrain during an uncontrolled descent." Sadly, this fatal accident was witnessed by the pilot's wife who was standing in a nearby hangar. According to the NTSB report, she observed her husband doing touch and go landings to runway 22. Just prior to the accident her husband approached to land on runway 22. The airplane never touched down on the runway. As the airplane neared the runway she observed it do a slight lift back up to about the height of a 2 1/2 story building. The right wing then raised up and the left wing dropped down. She stopped watching the airplane and ran to a person at another hangar to call for help. Visual meteorological conditions prevailed at the time of the accident with winds at 310 degrees at 11 knots. The pilot had total time of 87 hours of which 21 were logged in the Cherokee Six. Too much to look at . . . Too little time! Having the distinct advantage of observing many students and low time pilots as they commence their final approach to landings, I get to see a great deal of confused thinking taking place. I can see their eyes rapidly shifting up and down, left and right as they frantically look for queues on how best to land their airplane. I can only imagine the confusion that is going on in their brains as they are bombarded by a virtual flood of visual information. Such may have been the case with the Cherokee Six pilot. The focus should be exclusively on AIRSPEED and RUNWAY!
The two most important elements that count when making that final approach to landing are: airspeed and runway. Pilots who are able to keep these two elements in the center of their scan and thinking seldom have difficulty with landings. Practice this as you make your approach to landing. Call out your airspeed as you come over the runway threshold. Know what it is the moment your wheels touch the runway surface. Had the Cherokee Six pilot developed this skill, chances are he would have not experienced his tragic end.
This fact was celebrated last Saturday morning (October 29) with a dedication of recently constructed hangars. Present to be recognized were U.S. Congressman Tom Reynolds, R-NY and NY State Senator Marylou Rath (pictured center). Reynolds and Rath were both instrumental in bringing in over $11 million in federal and state grant funds for airport improvements. Also receiving special recognition for his truly unique contributions to the airport improvement was Richard Forrestel (pictured right). Richard is a remarkably talented individual with a marked propensity for getting things done! Neighbor obstacles overcome to make this happen! Bringing these improvements about was no small feat. Several airport neighbors attempted unsuccessfully to lobby local elected officials to withhold necessary zoning variances. A final court fight was averted through artful negotiations between airport leaders, local elected officials, and area residents. AOPA also assisted by providing guidance in this negotiation process. Today, Akron Airport enjoys a cordial relationship with its neighbors thanks to the implementation of a workable noise abatement program and neighbor-friendly pilots. And a Christian Airmen Education Foundation in the works! Not content to just operate a premier general aviation airport, Christian Airmen leaders are putting the finishing touches on a nonprofit educational foundation. Funds raised by this foundation will be used for aviation scholarships for deserving young people pursuing college studies in aviation and other worthwhile aviation endeavors.
Tragically, such was the case last month when the Columbia Aircraft Company announced the loss its first Columbia 400 aircraft in the mountains of Southern California. The ill-fated flight left El Cajon's Gillespie Field Monday morning, October 17th en route to Scottsdale, AZ. The aircraft was reported overdue Tuesday morning, and a Civil Air Patrol search was launched shortly thereafter. The victims were
Scottsdale residents James Barrett Lauchner, 49, wife Gina
Marie, 38 (pictured below) and
Tragically, general aviation suffers a fatal crash such as this every day of the year, on average. With over 75 percent of these crashes caused by pilot factors, we as an industry must take a more aggressive stand on the need for improved primary and recurrent flight training, with a greater emphasis on aeronautical decision making, risk assessment, and related human factors.

Knowledge versus Fear . . . The truth is, while potentially hazardous to flight, airframe icing is a manageable event that requires understanding rather than fear. Understanding leads to a safe response. Fear leads to dangerous response. For example, the knowledgeable pilot's response to airframe icing might include an immediate climb whereas a fearful pilot's response might lead to an immediate descent . . . often into hostile terrain below! A knowledgeable pilot understands the many different kinds of icing conditions and the factors that create them. The fearful pilot, on the other hand, sees a "one size fits all" kind of icing. This pilot may not be aware of the many defensive options he can exercise to deal with it. A knowledgeable pilot WILL fly confidently in wintertime clouds because he has carefully planned "back doors" that provide him immediate escape routes. The fearful pilot will either remain on the ground in the winter or will risk low altitude hazardous VFR flight to remain out of the clouds. Let's Become Ice-Savvy, Knowledgeable Pilots . . . We covered the various causes of icing in the October 9 issue of "Over the Airwaves." You can click HERE to go back and review this icing article. Now, let's look at the impact that icing has on the airplanes we fly.
Airframe icing creates three specific effects that require careful understanding. These effects are: 1. Aerodynamic Effect: The most hazardous aspect of structural icing is its aerodynamic effects. Ice can alter the shape of an airfoil, which can cause control problems, change the angle of attack at which the aircraft stalls, and cause the aircraft to stall at a significantly higher airspeed. Ice can reduce the amount of lift an airfoil will produce and greatly increase drag. It can partially block or limit control surfaces which will limit or make control movements ineffective. 2. Weight Effect: The shear accumulation of ice on the airframe adds considerable weight to the airplane. This added weight may prevent the airplane from maintaining altitude. 3. Roll Effect: Another hazard of structural icing is the possible uncommanded and uncontrolled roll phenomenon, referred to as roll upset, associated with severe in-flight icing. Pilots flying aircraft certificated for flight in known icing conditions should be aware that severe icing is a condition outside of the aircraft’s certification icing envelope. Roll upset may be caused by airflow separation (aerodynamic stall) which induces self-deflection of the ailerons and loss of or degraded roll-handling characteristics. These phenomena can result from severe icing conditions without the usual symptoms of ice accumulation or a perceived aerodynamic stall. A couple of things to remember about icing . . .
Congratulations go to Bombardier Business Aircraft for being the only civil aircraft manufacturer to conduct a safety seminar on human errors. Called a Safety Standdown, Bombardier is taking clear aim at the cause of 78 percent of all accidents in aviation –- pilot error. The event, billed as the industry's foremost safety event, was held on Oct. 25-27 in Wichita, Kansas. “The intent of Safety Standdown was to reduce accidents caused by human failure across the aviation industry as a whole, whether they occur during corporate, commercial or military missions,” stated Bob Agostino, director, flight operations, Bombardier Business Aircraft. “While we believe current training programs using simulators and other training devices are excellent, we also recognize that accident prevention requires more than simply perfecting technical skills.” This year's event focused on "Winning The War On Error," thereby enabling aviation professionals to better understand why and how crucial mistakes occur by providing in-depth, knowledge-based training in areas such as fatigue, nutrition and psychological factors. Bombardier's "Winning the War on Error" represents a refreshingly new approach to pilot training. It did this by focusing attention on the many human factors that contribute to aviation accidents. These factors include aeronautical decision making, risk assessment, and human judgment factors. These are the factors that contribute significantly to pilot-induced errors that result in fatal accidents. In summary, learning to control an airplane is a relatively simple task. The real challenge comes in learning what control inputs to make when things begin to go wrong. For example, in the face of imminent ground obstacles, do you raise the nose or lower it? When icing builds on the wings, do you climb or descend? When tossed into an upset where the instruments tumble, which gauge do you look at? When a wind gust forces your nose to the right when on the landing rollout, which way do you turn the yoke or stick! (Don't say to the left!) Remember, things go wrong quickly. It is easy to sit on the ground and take a minute or two to decide on the correct inputs in the above examples. The real question is, which input are you going to make instantly when all heck is going on in the cockpit?? Make the correct choice, you live. Make the wrong choice, you've ruined your day, your airplane, and possibly the rest of your life! Now add a couple of additional complicating factors such as (1) fatigue; (2) fear; (3) hunger/thirst; (4) conflicting information; (5) workload; and (6) disruptive passengers! These and many other complicating factors are seldom introduced in the traditional training environment. Most are never evaluated during the traditional private pilot, instrument, or commercial checkrides! Why? Because you won't find them addressed in the Practical Test Standards.
Winning the War on Error should be the major theme
in all of today's and tomorrow's training curricula. It
should be the area of training emphasis in all of today's and
tomorrow's glossy flying magazines. It should be the major
forum theme at aviation gatherings. Imagine,
if we win the war on error, we could eliminate over 75 percent
of all general aviation accidents. Indeed, it is a war
worth waging!
