What should be done to a pilot's arms during the incapacitation drill?

During the incapacitation drill, securing a pilot's arms by crossing them behind the shoulder harness is crucial for several reasons. First, this action prevents the incapacitated pilot from inadvertently interfering with the aircraft's controls, which could compromise the safety of the flight. By securing the arms, it ensures that they cannot move freely, thereby reducing the risk of accidental inputs that could lead to erratic flying behavior.

Additionally, this method creates a more stable position for the pilot's body, aiding in managing the overall emergency situation. It allows the remaining, capable pilot to focus solely on flying the aircraft and executing emergency procedures without distraction or the added complexity of dealing with an unrestrained pilot.

Securing the arms behind the shoulder harness ensures that the incapacitated pilot is held in a manner that is safe and does not compromise the critical actions that need to be taken during such an emergency, which highlights the importance of adhering to established protocols in aviation safety situations.
