FAA Ground School Practice Test

If Dallas Executive (RBD) Tower is not in operation, which frequency should be used as a common traffic advisory frequency (CTAF)?

1. 126.0 MHz

2. 127.25 MHz

3. 124.65 MHz

4. 119.8 MHz

The correct answer is: 127.25 MHz

When the Dallas Executive Tower is not operational, pilots must utilize a Common Traffic Advisory Frequency (CTAF) to communicate with each other and maintain situational awareness. The appropriate frequency for this purpose is 127.25 MHz. CTAFs are designated for non-towered airports or Air Traffic Control (ATC) facilities that are temporarily closed. These frequencies allow pilots to announce their intentions and listen for other aircraft in the vicinity, facilitating safer operations. In the context of Dallas Executive, 127.25 MHz has been established as the correct CTAF, which is crucial for ensuring that all pilots are on the same page regarding their movements around the airport and its airspace. It's important for aviators to be familiar with the designated CTAF frequency to enhance communication and safety in shared airspace. Knowing the correct frequency allows pilots to maintain an effective line of communication, thereby reducing the potential for misunderstandings and ensuring a higher level of safety for all aircraft operating in the area.
