Final answer:
The first pilot action once an aileron control jam is identified is to apply opposite aileron. This action helps to regain proper control and stabilize the aircraft.
Step-by-step explanation:
The first pilot action once an aileron control jam is identified is to apply opposite aileron.
When an aileron control jam occurs, one aileron becomes stuck or unresponsive. To counteract this, the pilot must apply opposite aileron by using the control inputs to move the ailerons in opposite directions.
This action helps to regain proper control and stabilize the aircraft.
