What is the purpose of MULTICOM frequency usage?

The purpose of MULTICOM frequency usage is to allow pilots to self-announce at uncontrolled airports. When operating at airports that do not have an operating control tower, pilots use MULTICOM frequencies to communicate their intentions and positions to others in the vicinity. This self-announcement helps to enhance safety by keeping all pilots informed about each other’s activities, thereby facilitating better situational awareness and promoting orderly traffic flow even in the absence of a control tower.

At uncontrolled airports, where no air traffic controllers are present to manage the traffic, this self-communication becomes vital. Pilots typically announce their arrival, intentions for landing, takeoff, and any other pertinent maneuvers to alert other pilots who may be in the area. Utilizing MULTICOM frequencies effectively contributes to a safer flying environment, as it minimizes the risk of collisions and misunderstandings among pilots operating in the same airspace.
