Definition
A written, sequenced list of items a pilot reads and acts on to verify that required actions, configurations, or system checks have been completed correctly at a specific phase of flight or operation.
Plain English
A printed or digital list of steps the pilot follows to make sure nothing important is missed before, during, or after each part of the flight.
Context Anchor
In the Airplane Flying Handbook, you may see this term when preparing for maneuvers, making sure the airplane is configured properly, and confirming that required safety steps have been completed.
Derivation
From 'check' (to verify or confirm) plus 'list' (an ordered set of items). Together: a list used to verify each item has been done.
Why Pilots Care
Using checklists ensures consistent procedures and reduces the risk of overlooking critical steps that could affect safety.
Intuition Check
A checklist is not just a reminder list. In aviation, it is a verification tool used at specific times to confirm that critical actions are complete.
Example Sentence 1
Before takeoff, the pilot ran the before-takeoff checklist and confirmed flaps set, trim set, and controls free.
Example Sentence 2
During the emergency descent, the crew referred to the appropriate checklist to verify each step.
