Ground, Tower, Approach or Center: Who to Call

One of the most confusing things for new pilots: which controller owns which part of the flight. Here is the whole map, in order. · 6 min read

To a new pilot, "ATC" can feel like one giant faceless system that you are somehow supposed to know how to navigate. In reality it is a relay team. Air traffic control is split into separate facilities, each responsible for one phase of flight, and they hand you forward from one to the next in a predictable order as your flight progresses. Once you see the sequence, the mystery evaporates: at any given moment there is exactly one facility working you, and you always know who is next. Here is the whole chain, from the ramp to cruise and back down.

The order of a typical flight

Clearance Delivery — at busier fields, this is your first call: you copy your IFR clearance or VFR departure instructions here before you even taxi.
Ground — owns the taxiways. Everything between the ramp and the runway hold-short line: taxi out and taxi back in.
Tower — owns the runway and the immediate traffic pattern. Takeoff clearances, landing clearances, and pattern sequencing.
Departure — a radar facility that takes you as you climb out after takeoff, keeping you clear of other traffic.
Approach — a radar facility that handles arrivals into a busy terminal area (Class C or B), giving vectors and sequencing you to the airport.
Center (ARTCC) — owns the big en-route chunks between terminal areas, i.e. your cruise. The high-altitude, long-distance controllers.

Read that list top to bottom for a departure and bottom to top for an arrival. On a cross-country you might touch every one of them: Clearance, Ground, Tower, Departure, Center, then Approach, Tower, and Ground at the far end. Each one hands you to the next with "contact [facility] on [frequency]."

At a non-towered field

Not every airport has all of these. At a non-towered field there is no Ground or Tower at all — you self-announce your intentions on the CTAF for taxi, takeoff, and landing, and see-and-avoid does the sequencing. You can still pick up Approach or Center en route for flight following; you just do not have a local tower to talk to.

💡 The one rule that never fails: whoever you talked to last still has you, until they explicitly hand you off. If you are ever unsure who to call, it is the last facility you were talking to — key up and ask them.

💡 The only way this becomes automatic is saying it out loud, dozens of times, before you key a live mic. That is exactly what ATCpal is for — practice the calls for each facility in sequence. Practice it free at atcpal.app.
