In uncontrolled terminal area operations, what frequency must all inbound traffic monitor from 10 miles out?

In uncontrolled terminal area operations, all inbound traffic must monitor the Common Traffic Advisory Frequency (CTAF) from 10 miles out. The CTAF is specifically designated for use in uncontrolled airspace to facilitate communication between pilots in the vicinity of an airport. By monitoring the CTAF, pilots can receive and relay information regarding their intentions, positions, and any other relevant traffic that may be present, thereby enhancing situational awareness and safety during approach and landing sequences.

Using the CTAF is critical in these scenarios because it helps establish a shared communication platform among all aircraft operating in the area, allowing for better coordination and minimizing the risks of collisions. This practice aligns with standard operating procedures in uncontrolled airspace, ensuring that all pilots are informed and can make better-informed decisions as they approach the airport.

The other frequencies mentioned serve different purposes and are not designated for the same type of communication required during inbound traffic operations. This distinction highlights the importance of utilizing the correct frequency in specific airspace contexts to maintain safety and efficiency.
