What frequency should be monitored when close to an airport that lacks a control tower?

When operating close to an airport that does not have a control tower, monitoring the common frequency is essential for ensuring safety and communication among pilots. The common frequency is usually designated for non-towered airports, allowing pilots to announce their positions and intentions to each other. This practice helps to increase situational awareness and coordinate traffic among those operating in the vicinity, reducing the risk of mid-air collisions or other incidents.

This frequency facilitates the sharing of important information regarding approach or departure intentions, which is crucial since there isn't a control tower to manage aircraft movements. By using this common frequency, pilots can maintain a safe level of communication, contributing to a safer flying environment around the airport.

Other frequencies, such as emergency, high-traffic, or commercial, do not provide the necessary communication framework for non-towered operations and are less relevant for pilots navigating in such areas. Understanding the importance of the common frequency in these situations helps enhance safety for all nearby aircraft.
