Plain English Meaning

The work a pilot does after the flight is over — shutting the aircraft down properly, walking around it to check for any damage, filling in the logbook, and thinking back over how the flight went.

Full Definition

The phase of a flight operation that begins after the aircraft has landed and been secured, during which the pilot completes shutdown procedures, inspects the aircraft, records flight data, and reviews the conduct of the flight.

Context Anchor

Seen in training records, instructor discussions, flight reviews, and after-flight procedures.

Derivation

From 'post-' (Latin, meaning 'after') and 'flight.' The prefix signals an action that follows the main event — in this case, everything done after the flight has ended.
