communication with the FSS. e. Information Provided by Aeronautical Advisory Stations (UNICOM) 1. UNICOM is a nongovernment air/ground radio communication station which may provide airport information at public use airports where there is no tower or FSS. 2. On pilot ... weather information, wind direction, the recommended runway, or other necessary information. If the UNICOM frequency is designated as the CTAF, it will be identified in appropriate aeronautical publications. f. Unavailability of Information from FSS or UNICOM Should…

FSSs, company radio, or appropriate military facilities capable of performing these services. 2. An ARTCC is divided into sectors. Each sector is handled by one or a team of controllers and has its own sector discrete frequency. As a flight ... progresses from one sector to another, the pilot is requested to change to the appropriate sector discrete frequency. 3. Controller Pilot Data Link Communications (CPDLC) is a system that supplements air/ground voice communications. The CPDLC’s principal operating criteria…

strictly limited to those areas/altitudes specifically authorized in the Chart Supplement or appropriate supplement. b. To use the VOT service, tune in the VOT frequency on your VOR receiver. With the Course Deviation Indicator (CDI) centered, the omni-bearing selector ... bearing selector should read 180 degrees with the to/from indication showing “to.” Should the VOR receiver operate an RMI (Radio Magnetic Indicator), it will indicate 180 degrees on any omni-bearing selector (OBS) setting.

Chapter 7: Radio Communication Procedures › Traffic Advisory Practices at Airports without Operating Control Towers › Understanding Communication on a Common Frequency
Frequency The key to communications at an airport without an operating control tower is selection of the correct common frequency. The acronym CTAF, which stands for Common Traffic Advisory Frequency, is synonymous with this program. A CTAF is a frequency ... airport without an operating control tower. The CTAF may be a UNICOM, MULTICOM, FSS, or tower frequency and is identified in appropriate aeronautical publications…
