Aircraft freqency? Is there a common frequency used by planes/helicoptors? Private and commerical?

Answer 1

the range from 107.9 Mhz to 135.95 Mhz is used internationally for aviation of which 107.9 to 117.95 is for navigation and 117.95 to 135.95 is for communication.

Answer 2

in the UK all the air band used to be just above 108Mhz FM (just above the top end of a normal FM domestic radio), there were also two fixed frequency weather forecasts broadcasting for pilots. you could hear the incoming call signs from the planes and the towers speaking to them giving them change of courses using degree vectors and heights to descend to, stacking over airports etc... i dont know how it is nowadays, its probably all digital and encoded, but i used to have an air band radio receiver and it was clear, heard concorde call the tower loads of times using the call sign 'speed-bird' then hear it fly over my house on the flight path into london, but if you manage to tune in above 108Mhz + and hear a continual announcemnet talking about cloud cover at height (eg 6 oktas at 5000ft culumus) then you know youve found the weather broadcast, the pilots are just on either side of that, take a look at a flight simulator on the net eg flightgear.com load up the boeing 737-300 and take a look at the instrument panel and radio adjustments, might bring my info up to date

Answer 3

There are many, the fella above nailed most of it right on the head.

The one that someone is ALWAYS listining to is 121.5

thats the emergency frequency and should ONLY bu used for such.

Answer 4

Radio communications are done through ATC or Air Traffic Control and every Controller has his or her own frequency to talk to airplanes in their airspace... when you start your flight in most towered airports you will talk to ground control to get clearance to taxi to the runway on one frequency... they will give you a tower frequency to switch to for getting takeoff clearance... then the tower will give you a departure frequency to change to when you are clear of the airport... then the departure controler will give you another frequency to change to to talk to center or the controlers that have the airplanes all the way through the cruise portion of the flgiht... there are many centers in the US spread pretty far apart... you get transfered from center to center as you cross the US such as minneapolis center will transfer you to chicago center or cleveland center on a flight through minnesota or iowa heading east. The center controler begins your descent and sends you to an Approach controler that will have you until he sends you to usualy another approach controller in charge of lower altitudes and that contoller to a tower contoller for clearance to land then another ground controller for clearance to taxi to the gate or parking... so no.... many different radio frequencies.

Answer 5

Emergency (Guard) frequencies that should by monitored at all times by aircraft are UHF 243.0 and VHF 121.5.

Answer 6

121.5 or 243 (guard freq.) Worldwide.

Canada: 126.7 VHF is the common freq. for VFR traffic in Uncontrolled Airspace.

Answer 7

There are two freqs used commonly at uncontrolled airports (most airports are uncontrolled). We used to call them unicom, now it's common traffic advisory frequency, CTAF. They are 122.8 and 123.0.
