Lesson plan
Falling leaf
A falling leaf (also called a rudder stall or oscillation stall) is a maneuver in which an aircraft performs a wings-level stall (the airplane stops flying and starts falling) which begins to induce a spin. This spin is countered with the rudder, which begins a spin in the opposite direction that must be countered with rudder, and the process is repeated as many times as the pilot determines. During the maneuver, the plane resembles a leaf falling from the sky; first slipping to one side, stopping, and then slipping to the other direction; continuing a side-to-side motion as it drifts toward the ground.
