Definition
A geographical or navigational reference point used along a route to confirm the aircraft's position and verify that the flight is progressing as planned. Check points are typically prominent landmarks, navigation fixes, or designated waypoints noted on the flight plan or chart and used to compare actual position and time against planned position and time.
Plain English
A known point along your route that you use to confirm where you are and whether you're on track and on time.
Context Anchor
Seen in IFR flight planning, route review, and flight logs when a pilot checks progress from one planned point to the next.
Derivation
From 'check' (to verify) and 'point' (a specific location). The term reflects its function: a specific spot where the pilot checks progress against the plan.
Why Pilots Care
Enables timely confirmation of position and resource management so the pilot can correct any deviation before it becomes a problem in instrument conditions.
Intuition Check
A Check Point is not a place where the aircraft must stop or where someone checks the pilot in. It is a planned location used to verify position and progress during the flight.
Example Sentence 1
Crossing the river two minutes ahead of schedule, the pilot logged the check point and updated the estimated time of arrival.
Example Sentence 2
At the next check point the pilot updated the estimated time of arrival for the destination.
