Operation quiz

Where there is no tower, Flight Service, or UNICOM station on the airport, use MULTICOM frequency 122.9 for self-announce procedures. Such airports will be identified in the appropriate aeronautical information publications.

CTAF is a frequency designed for the purpose of carrying out airport advisory practices and/or position reporting at an uncontrolled airport (which may also occur during hours when a tower is closed). The CTAF may be a UNICOM, MULTICOM, FSS, or tower frequency and is identified in the appropriate aeronautical publications. A solid dot with the letter "C" inside indicates CTAF. When the control tower operates part time and a UNICOM frequency is provided, use the UNICOM frequency.

Most sUAS are designed to fly normally with minimal impact on features or controllability if GPS signals are degraded or lost. Loss of GPS is not an emergency and is not considered to be a loss of link between the unmanned aircraft and the control station. If the failure of GPS does result in a flyaway or other dangerous situation, it should be treated as an emergency.

Pilots of inbound traffic should monitor and communicate as appropriate on the designated CTAF from 10 miles to landing. Pilots of departing aircraft should monitor/communicate on the appropriate frequency from start-up, during taxi, and until 10 miles from the airport unless the regulations or local procedures require otherwise.

Traffic information will be given in azimuth from the aircraft in terms of the 12-hour clock. Thus, each hour would constitute an angle of 30 degrees. Picture a clock in your lap; three o'clock is to your right, nine o'clock is to your left, twelve o'clock is straight ahead, and six o'clock is behind you. If an aircraft is proceeding on a heading of 090° (east), traffic located at the three o'clock position would be 90° right of the nose, south of the aircraft. If the sUAS is being operated to the south of the aircraft, the aircraft itself is to the north of the operation.
