Definition
An air traffic control facility, normally co-located with an approach control, that uses radar to provide separation, vectors, and climb instructions to IFR aircraft (and participating VFR aircraft) immediately after takeoff until they are handed off to an en route center or other facility.
Plain English
The radar controller who looks after you in the first few minutes after takeoff, telling you which way to turn and how high to climb until you are passed on to the next controller.
Context Anchor
Seen on departure procedure notes, cockpit frequency setups, and radar-controlled departure diagrams where the pilot is told which controller or frequency to contact after takeoff.
Derivation
DEP is a common shortening of departure, meaning leaving. CON is a common shortening of control, meaning the controller or control position managing that part of the flight. Together, DEP CON means the control position that handles the leaving phase of the flight.
Why Pilots Care
Provides immediate separation and routing guidance during the busiest and most critical phase of an IFR flight, reducing pilot workload and collision risk.
Intuition Check
DEP CON is not the act of taking off. It is the air traffic control position or frequency responsible for handling you after takeoff.
Example Sentence 1
After takeoff, the tower instructed us to contact departure control on 124.35.
Example Sentence 2
Departure control gave me a left turn to 180 and cleared me to 4000 feet.
