What is clearance delivery frequency?
Clearance Delivery Frequency is initial clearance from ATC before you take off.
The idea behind using a dedicated frequency for this is that it avoids tying up the ground control frequency (used for authorizing ground movement on taxiways and such) with long clearances and readbacks..
What frequency does the military use?
The primary communications mode is narrowband FM, but some AM is used by air units of the various services for tactical air-to-air comms. The military has a BIG (175 MHz) military aircraft band in the 225-400 MHz range. Basic spacing between channels is 25 kHz.
What frequency do airplanes use?
In the US the civil aircraft communications band (118-137 MHz) generally uses 25 kHz spaced channels. As of 2010 aeronautical enroute and flight test stations may use 8.33 kHz spaced channels in the 121.4-123.6, 128.825-132.0 and 136.5-136.875 MHz ranges.
How do pilots communicate with air traffic?
The standard method of communication between an air traffic controller and a pilot is voice radio, using either VHF bands for line-of-sight communication or HF bands for long-distance communication (such as that provided by Shanwick Oceanic Control).
How do I listen to airport frequencies?
To listen to your local air traffic control, you’ll need to obtain a radio scanner that’s capable of receiving frequencies between 118.0 and 136.975 MHz. Then, go on sites like skyvector.com to find an aeronautical sectional chart of your local area.
Is listening to air traffic control illegal?
You can listen to air traffic control radio transmissions It is illegal under the Wireless Telegraphy Act 1949 2006 to listen to anything other than general reception transmissions unless you are either a licensed user of the frequencies in question or have been specifically authorised to do so by a designated person.
Where do I find FSS frequency?
Normally, you would communicate with Flight Service through the frequencies shown on the sectional chart. The Flight Service frequencies are listed in a box above certain VOR stations. The most common frequencies are 122.2, 122.4, or 122.6.
How do you call FSS on a plane?
There is a little mystery as to the best way to access a flight service station while flying en-route. Flight Service stations are serviced a single phone number throughout the continental United States: 1-800- WX-BRIEF. Use this phone number to access any of the services that an FSS provides.
Is 121.5 still monitored?
Flight Service Stations will con- tinue to monitor 121.5 MHz, and aircraft pilots are technically still required to monitor this frequency at all times if it’s possible with installed equipment. After all, 121.5 MHz still remains the GARD frequency for airborne emergencies.
Is UHF FM or AM?
UHF = Ultra High Frequency and has NOTHING to do with whether the signal is AM, FM or something else. In other words, UHF refers to the “band” that the frequency is in. AM and FM are types of modulation. There are plenty of other modes of modulation as well.
Are aircraft frequencies AM or FM?
Aircraft use assigned frequencies in the 108 to 135 MHz frequency range which is assigned by the FCC to aviation services. The radios use amplitude modulation (AM) for transmissions.
What is ground frequency?
Ground control frequencies are provided to eliminate frequency congestion on the tower (local control) frequency and are limited to communications between the tower and aircraft on the ground and between the tower and utility vehicles on the airport, provide a clear VHF channel for arriving and departing aircraft.
