Definition
Departure procedures (DEPPROC) are published instructions that guide pilots safely from the runway environment to the en route structure. They include Obstacle Departure Procedures (ODPs), which provide obstacle clearance, and Standard Instrument Departures (SIDs), which provide an organized flow into ATC routing. These procedures specify required tracks, climb gradients, altitudes, and headings to follow after takeoff.
Plain English
A set of published steps a pilot follows right after takeoff to climb out safely and join the route ATC expects them to fly.
Context Anchor
You may see DEPPROC in FAA notices, flight planning information, or departure information for an airport.
Why Pilots Care
Departure procedures keep aircraft clear of terrain and obstacles during the critical climb phase and fit each flight into the wider ATC traffic flow. Missing or misflying a DEPPROC can put an aircraft into rising terrain or in conflict with other traffic.
Intuition Check
DEPPROC does not mean a general habit for taking off. It refers to specific departure instructions that may be published, assigned, changed, or unavailable.
Example Sentence 1
Before takeoff, the pilot reviewed the DEPPROC to confirm the required climb gradient and initial heading.
Example Sentence 2
Clearance delivery assigned the DEPPROC so the aircraft would stay clear of nearby traffic during departure.
