What frequency should be used as a Common Traffic Advisory Frequency (CTAF) at Coeur D'Alene?

The appropriate frequency for a Common Traffic Advisory Frequency (CTAF) at Coeur D'Alene is indeed 122.8 MHz. This frequency is typically used at many airports, particularly those without an operating control tower, to facilitate communication among pilots when they are approaching or departing the airport.

In an airspace where a control tower is absent, pilots use the CTAF to announce their intentions, such as takeoffs, landings, and other maneuvers, ensuring that all aircraft in the vicinity are aware of each other's presence and intentions. Using the correct frequency is essential for safety and situational awareness, as it minimizes the risk of mid-air collisions and promotes smoother operations at the airport.

The other frequencies listed serve specific purposes or are designated for different air traffic control communications, but 122.8 MHz is the standard CTAF used at many locations, including Coeur D'Alene, for non-towered airport operations.
