In emergency scenarios, what is the direct action to take for a jammed aileron?

In emergency scenarios where aileron jam occurs, pulling the aileron disconnect handle is the correct action to take. This handle effectively disconnects the jammed aileron from the control system, allowing the pilot to regain control of the aircraft's roll. The aileron disconnect is specifically designed for situations where the ailerons may not respond due to mechanical failure or obstruction, permitting the use of alternate control measures if necessary.

Although reducing the descent rate, pressing the autopilot disconnect, or pulling the elevator disconnect handle may be relevant in various emergency situations, they do not directly address the problem of a jammed aileron. The focus must be on restoring roll control, which is why disconnecting the aileron is the most immediate and effective response to ensure safe maneuverability of the aircraft.
