Definition
The procedure of stopping the airplane's engine after flight or ground operations, performed by following the manufacturer's checklist sequence — typically idling the engine briefly to allow temperatures to stabilize, moving the mixture control to idle cut-off to starve the cylinders of fuel, then turning off the ignition (magnetos), master switch, and other electrical systems in the prescribed order.
Plain English
The set of steps a pilot follows to safely stop the engine and turn off the airplane's systems at the end of a flight or before leaving the cockpit.
Context Anchor
Seen in the airplane checklist after parking, and in training when learning how to finish a flight safely.
Why Pilots Care
Following the correct sequence prevents engine damage, propeller strikes, and fire risks that can occur from improper shutdown.
Intuition Check
Engine shutdown is not just turning a key off like a car. In an airplane, it is a checklist procedure that stops the engine and secures the airplane in a controlled way.
Example Sentence 1
After taxiing to the ramp, the pilot completed the engine shutdown checklist by pulling the mixture to idle cut-off and then turning off the magnetos and master switch.
Example Sentence 2
During engine shutdown the pilot verified both magnetos were off and the master switch was set to off before exiting the cockpit.
