Definition
The published fix at which a Standard Instrument Departure (SID) ends and the en route portion of the flight begins. It is the last charted waypoint of the SID, where the aircraft transitions from the departure procedure to its filed en route route or to a clearance issued by ATC.
Plain English
The point on the chart where a published departure procedure stops. Once the aircraft passes it, the departure is over and the en route part of the flight begins.
Context Anchor
Seen on instrument departure procedures and in navigation database discussions, especially when a departure route ends at a named waypoint or fix.
Derivation
Terminating' comes from the Latin terminus, meaning 'boundary' or 'end.' The SID terminating point is literally the end-boundary of the departure procedure.
Why Pilots Care
Marks the precise moment the departure clearance obligations end and enroute navigation or new ATC instructions begin.
Intuition Check
“Terminating” does not mean the flight, clearance, or navigation is finished. It means this particular published departure route ends at that point.
Example Sentence 1
After crossing the SID terminating point, the crew began navigating directly to their first en route fix.
Example Sentence 2
The approach plate shows the SID terminating point as the handoff location to enroute navigation.
