When should a pilot announce their position at a pilot-controlled airport?

A pilot should announce their position at a pilot-controlled airport on each leg of the traffic pattern and during the approach. This practice is essential for maintaining situational awareness and ensuring safety in the uncontrolled airspace where other pilots may also be operating. By announcing positions such as "downwind," "base," and "final," a pilot provides critical information to others flying in the area, reducing the risk of potential collisions and allowing for better coordination among pilots.

Effective communication also helps to establish a predictable flow of aircraft movements, which is particularly important at airports that lack an air traffic control tower. Pilots using the radio to announce their intentions contributes to a safe and organized traffic pattern, enhancing the overall efficiency of airport operations.

Position reports are important throughout the approach and landing phases of flight, not just during specific instances, allowing all pilots in the area to be aware of each other's positions and intentions.
