Pilots use the tower frequency to coordinate their arrivals and departures safely, giving position reports and acknowledging other aircraft in the airfield traffic pattern. In many locations, smaller airports use pilot-controlled lighting systems when it is uneconomical or inconvenient to have automated systems or staff to turn on the taxiway ...
In the United States, radio frequencies made available by the Federal Communications Commission for use as UNICOM are: [8] Airports with an Air Traffic Control tower or FSS (Alaska only) on the airport. [8] 122.950 MHz; Airports without an Air Traffic Control tower or FSS on the airport. [8] 122.700 MHz; 122.725 MHz; 122.800 MHz; 122.975 MHz ...
A new control tower was constructed at the airport in 1962, [3] though regular airline service from Boeing Field ceased in 1971. [4] In 1981, the Airpark hangar complex was built to accommodate 20 business jets. [3] The Seattle Museum of Flight opened in 1987. An expansion of the Airpark hangar complex in 1988 added 16 more spaces. [3]
In addition to radio frequencies used to connect handsets with cellular base stations, other parts of the radio spectrum are used to interconnect base stations and the wired telephone network. Some frequency bands may be vulnerable to interference by existing services in adjacent frequency bands, such as UHF television broadcasting.
However, most of the layers of data on the charts include specific information about obstacles, airspace designations, and facility information (locations, radio frequencies, etc.). The legend divides these into several types of information, namely: airports, radio aids, traffic and airspace services, obstructions, topographic, and miscellaneous.
Pilots can find RCO frequencies in charts or publications such as the Chart Supplement or Canada Flight Supplement. [1] The RCO is used to make a radio call to the outlet as if the pilot were making the call directly to the FSS or FIC. The outlet will relay the call (and the briefer's response) automatically.
Automatic terminal information service, or ATIS, is a continuous broadcast of recorded aeronautical information in busier terminal areas.ATIS broadcasts contain essential information, such as current weather information, active runways, available approaches, and any other information required by the pilots, such as important NOTAMs.
Antenna array at Amsterdam Airport Schiphol. The VHF airband uses the frequencies between 108 and 137 MHz.The lowest 10 MHz of the band, from 108 to 117.95 MHz, is split into 200 narrow-band channels of 50 kHz.
