Plain English Meaning
A written training plan the instructor builds before starting an aircraft checkout, so each lesson is in the right order and nothing important is skipped.
Full Definition
In aircraft checkout and transition training, a structured outline developed by the instructor that sequences the ground and flight instruction needed to qualify a pilot in an unfamiliar aircraft, tailored to the pilot's experience, the aircraft's systems and handling characteristics, and the training objectives.
Context Anchor
Used in flight training, especially when an instructor is preparing a checkout, transition lesson, or review flight.
Derivation
Plan comes from an older word meaning a flat drawing or map. Action comes from a word meaning to do. Together, the phrase points to a mapped-out way of doing something, not just an idea.
