Does Deliberately Going Beyond Alarms in Stall Recovery Exercises Lead to Negative Training?

Abstract

We investigated whether deliberately going beyond alarms during aerodynamic stall recovery exercises may result in negative training. Two groups of 20 airline pilots received stall recovery training in a moving-base simulator. The “delayed-response” group induced the stall themselves. The “immediate-response” group was presented with paused situations and had to recover immediately after unpausing. In a surprising transfer test, the pilots in the delayed-response group showed less aggressive unloading, and experienced significantly more time pressure compared to the pilots in the immediate-response group. In a stall cue recognition test, the delayed-response group performed nearly significantly better. We conclude that experiencing the progression of an aerodynamic stall during training has positive effects on pilot performance, even if this requires unprocedural behavior.
