Definition
A written, sequential list of steps the pilot follows to start an aircraft engine safely and correctly. It typically includes verifying brakes set, mixture, throttle, propeller, fuel selector, master switch, magneto/ignition position, area-clear call, and post-start checks of oil pressure and engine instruments. The checklist is published by the airframe or engine manufacturer in the Pilot's Operating Handbook (POH) or Aircraft Flight Manual (AFM) and is specific to that make and model.
Plain English
The step-by-step list the pilot reads and follows to start the engine in the right order, without skipping anything.
Context Anchor
Used on the ground before engine start, usually after the pilot is seated, the area around the airplane is clear, and the airplane is ready to be started.
Why Pilots Care
Following it prevents engine damage, fire hazards, and ensures compliance with manufacturer procedures.
Intuition Check
Do not treat an engine start checklist as a casual reminder list. In aviation, it is the airplane’s required start sequence, and the exact order matters.
Example Sentence 1
After completing the preflight inspection, the student pilot opened the POH to the engine start checklist and worked through each item in order.
Example Sentence 2
The engine start checklist includes checking for clear prop and priming the engine if necessary.
