CTAF Self-Announce Calls at a Non-Towered Field
No tower, no clearances — just you and other pilots announcing intentions. Here is the full self-announce script, the pattern-entry standard, and the etiquette that prevents mid-airs. · 8 min read
The majority of airports in the country do not have a control tower. At a non-towered field there is no controller to clear you to land, take off, or taxi — you are responsible for separating yourself from other traffic by see-and-avoid, and the radio is how everyone shares their intentions to make that possible. Instead of clearances, pilots self-announce their position and what they are doing on the Common Traffic Advisory Frequency (CTAF). Nobody answers; you are broadcasting to whoever is out there. Because there is no controller imposing order, good radio discipline and a predictable pattern are what keep everyone safe — this is arguably where clear radio work matters most.
The self-announce format
Every non-towered call follows the same shape: airport name, who you are, where you are, what you intend, and the airport name AGAIN. Saying the airport name first and last is not redundant — many nearby airports share the same CTAF, so bracketing your call with the field name tells other pilots which airport you are talking about:
The pattern calls, in order
Here is the standard sequence for arriving and flying the pattern. You do not have to call every single position on a quiet day, but these are the expected reporting points, and calling them is how you stay predictable to others:
- Inbound (about 10 miles out): "…ten miles south, inbound for landing, will enter left downwind Runway 20…"
- Entering the pattern: "…entering left downwind Runway 20…"
- Base: "…turning left base Runway 20…"
- Final: "…turning final Runway 20, full stop…" (or "touch and go")
- Clear of the runway: "…clear of Runway 20…" — this one matters: it tells someone on final the runway is now free.
How to enter the pattern
The recommended entry is a 45-degree angle to the downwind leg, at pattern altitude, on the side where the pattern is flown (usually left traffic). Announce your intentions as you set up so aircraft already in the pattern know where to look for you: "…entering the 45 for left downwind Runway 20." Avoid straight-in approaches at busy non-towered fields — they conflict with aircraft already flying the pattern, who may not expect you.
Departing
Before you taxi onto the runway, announce your departure and check the final approach is clear (look AND listen). Then announce your departure direction so inbound traffic can plan around you:
The mistakes to avoid
- Saying "tower" — there is no tower. Say the airport name plus "traffic."
- Giving only a runway number with no airport name — several fields share a CTAF and pilots will not know if you mean their airport.
- Assuming radio silence means no traffic. Some aircraft have no radio (perfectly legal at non-towered fields). Always keep looking outside — the radio supplements your eyes, it does not replace them.
- Over-talking. Keep calls short and standard so the frequency stays clear for everyone.
