At nontower airports without an FSS or UNICOM, what is the usual CTAF frequency?

• A. 122.8 MHz
• B. 122.9 MHz
• C. 123.0 MHz
• D. 124.0 MHz

Answer: (B)

At nontower airports that do not have a Flight Service Station (FSS) or UNICOM, the common traffic advisory frequency (CTAF) that is typically used is 122.9 MHz. This frequency serves as a means for pilots to communicate their intentions and maintain situational awareness while operating in the vicinity of the airport. The selection of 122.9 MHz for CTAF in these contexts is rooted in established practices within the aviation community, allowing for standardization and consistency across nontower airports. By utilizing this specific frequency, pilots can ensure that they are on the same wavelength as others operating in the area, contributing to overall flight safety by enhancing communication during takeoffs, landings, and ground operations. Other frequencies are used for different purposes or have become associated with specific locations or services and are not universally designated as the CTAF for nontower airports.
