Definition
Specific geographic points -- such as navigation fixes, ground features, or radar-identifiable positions -- that ATC has formally established for pilots to report over, turn at, or use as reference during a departure, arrival, or route segment.
Plain English
Pre-chosen points on the ground or in the air that controllers and pilots both use as agreed reference spots during a flight.
Context Anchor
Seen in radar-controlled departure instructions when air traffic control routes an aircraft from the airport toward the next part of its flight route.
Derivation
Designated' comes from the Latin 'designare,' meaning 'to mark out' or 'point out.' A designated checkpoint is therefore a point that has been formally marked out in advance -- not one the pilot picks on their own.
Why Pilots Care
Ensures pilots provide accurate position information to air traffic control, maintaining safe aircraft separation.
Intuition Check
Do not read this as any convenient point the pilot chooses. A designated checkpoint is a specific point named by the clearance, procedure, or route.
Example Sentence 1
After takeoff, the pilot flew the radar-vectored departure via the designated checkpoints issued in the clearance.
Example Sentence 2
During the radar vector, the aircraft passed the first designated checkpoint and advised ATC of its position.
