Definition
An airport that does not have an operating air traffic control tower. Pilots operating at a non-towered airport are responsible for sequencing themselves into and out of the traffic pattern, announcing their position and intentions on a Common Traffic Advisory Frequency (CTAF), and visually maintaining separation from other aircraft.
Plain English
An airport with no controller telling aircraft where to go. Pilots coordinate with each other by radio and by looking outside, following standard procedures for arriving, departing, and using the runway.
Context Anchor
Pilots encounter this term when planning arrivals, departures, traffic patterns, radio calls, and automated landing operations at airports without an active control tower.
Derivation
“Non-” means “not.” In aviation, “towered” refers to an airport served by an operating control tower, not simply an airport that has a tall building. So “non-towered” means the airport is not being served by an active tower controller.
Why Pilots Care
Pilots must follow self-announce procedures and remain vigilant because no air traffic control service provides separation or sequencing.
Intuition Check
Non-towered does not mean uncontrolled or rule-free. It means there is no active tower controller giving instructions, so pilots must use the published procedures and coordinate safely with other traffic.
Example Sentence 1
Approaching the non-towered airport, she announced her position on the CTAF ten miles out and entered the downwind at pattern altitude.
Example Sentence 2
At a non-towered airport, pilots scan for other traffic while making position reports on the common frequency.
