What frequency does MULTICOM operate on in uncontrolled airport areas in the U.S.?

MULTICOM operates on the frequency of 122.9 MHz in uncontrolled airport areas in the U.S. This frequency is designated for non-towered airport communications, allowing pilots to announce their intentions and coordinate their movements in scenarios where air traffic control services are not available.

Using 122.9 MHz enables pilots at uncontrolled airports to provide or receive information related to their flight operations, enhancing safety and situational awareness for everyone in the airspace. This frequency facilitates essential communication between pilots, ensuring that they can effectively manage their approach and landing, as well as takeoff, without the oversight of air traffic controllers.

The other frequencies listed are designated for different uses; for instance, 121.5 MHz is an emergency frequency, while 120.5 MHz is also used for air traffic control communications or may be used informally in certain contexts. Therefore, 122.9 MHz is specifically aligned with the established operating procedures for MULTICOM communications in uncontrolled areas.
