摘要

Every year structural icing claims a small but steady number of airplanes. Many of the accidents are on approach in clear air-after the airplane has already collected a load of ice. We look at it afterwards and wonder-the airplane had been doing fine-why did it crash well after it escaped from icing conditions? Full-scale airframe ice flight testing and our ability to reconstruct icing-related accidents have gotten more sophisticated. Consequently, we've learned that tail stalls, rather than wing stalls, may be the culprit in crashes that occur during the descent or approach phase of flight. This matters because pilots have been taught how to recover from wing stalls (lower the nose, add power) but not from tail stalls, and the recovery from tail stalls is precisely the opposite (raise the nose, raise the flaps, reduce power). The consequence of using the wrong recovery technique can be fatal.
