The Dangerous Stalls (We Never Teach)!

As educators, we often teach only what we ourselves were taught – conveying the same good (and bad) information or techniques in the same way we learned them. It takes courage to call out and change errors and omissions from our mentors (they are our heroes after all). It also takes creativity and effort to forge new pathways and techniques. But this is what is required to make progress in safety; learning, and changing the “time-honored formulas” based on new data. Consider new trends like “startle” which has transformed our understanding of Loss of Control. Or teaching landings by training slow flight low over the runway instead of just touch and goes. Similarly, focusing more on take-off and departure stalls can be more effective for safety since this area of flight is much more toxic than the time-honored base-to-final turn. Once we understand the static inertia of flight training techniques, it is easier to understand why accident rates stay fairly level. As educators, we often miss training in dangerous areas of flight that regularly challenge pilots – and regularly cause accidents.

Between 2008 and 2014, about 47 percent of fatal fixed-wing GA accidents in the United States involved pilots losing control of their aircraft in flight, resulting in 1,210 fatalities.

Killer stalls occur repeatedly in accident dockets but we fail to train them. The flight scenarios that create stalls in real life often occur because of sudden power changes; either a loss of power on take-off or the sudden application of power during a go-around. But we inevitably train only the constant power stalls that lack the sudden yaw forces that confuse pilots and power spin entries. Why don’t we train these situations where accidents happen? Probably because they are pretty advanced and can be pretty scary for learners. It takes a very careful and compassionate CFI to work through even the “plain vanilla” stalls to the point that a pilot can comfortably recover, developing useful habits. Taking stalls even further requires both a committed trainer and a willing learner. So it is essential to first “sell” the necessity of these maneuvers with their safety advantage; it is also essential to have the “buy in” from your learner. These should not be inflicted on a pilot, this should be a mutually agreed upon “safety mission” and that is why they are in the SAFE CFI-PRO™ curriculum. We have a duty as professional educators to take our “learners” into these common “dark corners” where bad things can happen. And they are especially effective “added value” on a flight review.

Imagine an aircraft on take-off in a steady, trimmed, Vy climb encountering a sudden loss of all power (if you have not tried either of these stalls, please take an experienced CFI along). Recovery from this surprise requires an immediate and aggressive push to reduce the angle of attack. And this is uncomfortable for many pilots due to the proximity to the ground. For untrained pilots, sudden power failures on take-off almost always end badly (even on dual flights). This should be over-trained at altitude until unloading the AOA becomes an instinctive reaction.

Now imagine a very different configuration, just over the runway in the landing configuration, transitioning into the flare and raising the nose. Just before the flare at a high angle of attack, the sudden power application (simulating a go-around) is often mishandled and results in a LOC. There is no extra altitude to spare and reactions here again must be over-trained to be precise and immediate. Both these variable power stalls should be practiced at altitude (with an experienced, compassionate CFI) until they are instinctive. Fly safe out there (and often)!
