What is the designation of an active runway at a non-towered airport?

At a non-towered airport, the designation of an active runway is advisory only. This means that while pilots are encouraged to announce their intentions and listen to others in the traffic pattern, there are no air traffic controllers present to enforce any rules or separation. Therefore, the communication regarding runway use is based on voluntary compliance and situational awareness among pilots.

Unlike controlled airports where air traffic control provides instructions and enforces compliance for safe operations, non-towered airports rely on pilots' self-organization through the exchange of information over common traffic advisory frequencies. This creates a collaborative environment where pilots can make informed decisions based on the movements of other aircraft.

Understanding this designation is crucial for pilots operating at non-towered airports so that they can safely navigate and communicate with other pilots in the vicinity. Such an environment requires a heightened level of situational awareness and proactive communication, emphasizing that the advisory nature means it is up to each pilot to act on the information shared.
