At Coeur D'Alene, which frequency should be used to self-announce position and intentions?

1. 121.5 MHz

2. 122.8 MHz

3. 123.85 MHz

4. 124.25 MHz

The correct answer is: 122.8 MHz

The correct frequency for self-announcing position and intentions at Coeur D'Alene is 122.8 MHz. This frequency is commonly used as a UNICOM frequency at many airports for non-towered communication. Pilots use this frequency to coordinate their activities, announce their locations in relation to the airport, and communicate their intentions to other pilots in the vicinity. In non-towered airspace, it is essential to maintain situational awareness and to communicate effectively with other aircraft, and using the correct frequency facilitates this vital exchange of information. Frequencies like 121.5 MHz are designated for emergency communications and should not be used for routine communications, while 123.85 MHz and 124.25 MHz may be used at other airports or for different purposes, but they are not specifically designated for self-announcing at Coeur D'Alene. Thus, 122.8 MHz is the appropriate choice for this scenario.
