Question: Where Do I Find FSS Frequency?

What frequency are airports?

Radio communication between the control facilities and the aircraft take place on a number of radio frequencies.

These frequencies are in the VHF (Very High Frequency) frequency range of 108 to 136 MegaHertz (MHz)..

What radio 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.

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.

What is FSS frequency?

FSS frequencies are all in the 122 and 123 MHz series; for example, 122.25, 122.3, 122.35, 122.45, 122.55, 122.6, 122.65, and 123.65 MHz. Remember the universal FSS frequency of 122.2 MHz, and that Flight Watch is 122.0. All FAA facilities monitor the emergency frequency, 121.5 MHz.

Are airport frequencies AM or FM?

Aviation doesn’t use AM radio broadcast frequencies (565 to 1605 KHz). They use AM modulation on Non-Directional Beacons (NDBs) below those frequencies, and they use mostly Single Sideband instead of AM modulation on HF frequencies (3–30 MHz).

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.

What is RCO in aviation?

Remote Communications Outlets (RCO) are remote aviation band radio transceivers, established to extend the communication capabilities of Flight Information Centres (FIC) and Flight Service Stations (FSS). … Classes A through G are used mainly for air/ground communications.

How do I find weather information on a flight?

Complete weather information is available by telephone call or visit to the nearest FAA Flight Service Station (FSS) or designated NOAA Weather Service Office. Information is also available from private commercial vendors. During periods of marginal weather, briefers are busy and telephone delays may occur.

How do I talk to FSS?

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 Flight Watch still active?

Traditionally the En Route Flight Advisory Service (EFAS)—Flight Watch—has been available anywhere in the U.S. on 122.0. The FAA will discontinue using 122.0 for both Flight Watch and Hi-Watch and make those services available on 122.2 and all remote communications outlet frequencies.

What is meant by frequency?

Frequency, in physics, the number of waves that pass a fixed point in unit time; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.

What is a talk around frequency?

It means “talking around the repeater”. So, Talk-a-Round (aka Direct) is where the mobile or portable talks simplex to others on the output frequency of the repeater they normally use. It is primarily used when a repeater is out of service, or you are out of range of it.

What does a FSS do?

A flight service station (FSS) is an air traffic facility that provides information and services to aircraft pilots before, during, and after flights, but unlike air traffic control (ATC), is not responsible for giving instructions or clearances or providing separation.

Why do aircraft use AM radio?

While FM has many advantages, AM is typically used in aviation. … Amplitude modulation, or AM radio, transmission is not subject to the capture effect. This is one reason that the aviation industry has chosen to use AM for communications rather than FM, allowing multiple signals to be broadcast on the same channel.

What frequency do helicopters use?

Use of air to air frequencies for aircraft and helicopters. In the FCC rules 47 CFR 87.187(j) it states: The frequency 122.750 MHz is authorized for use by private fixed wing aircraft for air-air communications. The frequency 123.025 MHz is authorized for use by helicopters for air-air communications.
