What does the term Air-Ground communication mean?

Two-way communication
Definition. Two-way communication between aircraft and stations or locations on the surface of the earth.

What is radio ground air?

Air-ground radiotelephone service includes commercial and general aviation services. Licensees may offer a wide range of telecommunications services to passengers and others on aircraft. The air-ground radiotelephone service operates on frequencies designated by the Federal Communications Commission.

How do airplanes communicate with ground?

In addition to satellites, some airplanes rely on high-frequency radio technology to communicate with air traffic controllers on the ground. High-frequency radio technology involves relaying the airplane’s location to a network of receivers, which eventually pass the data to air traffic controllers on the ground.

What frequency is ground to air communications?

The radio spectrum between 118.000 to 135.975 MHz is used for air / ground communications in the aeronautical mobile service. Previous use of 50 kHz bandwidth assignments yielded 360 channels. Reducing the bandwidth requirements to 25 kHz doubles the available assignment pool to 720 channels.

What would you use an air band radio for?

Airband or avionic radios are primarily used by pilots and Air Traffic Control as a means of two way communication and navigation.

How do pilot communicate with ATC?

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).

Why do planes still use radio?

When a plane is moving rapidly, it will change cell towers frequently. This has the same problems as above. Cell communications is designed for Person-to-Person during a single call. Aviation radio is designed so that everyone can hear everyone else’s communications.

Who invented air ground communication?

In 1917, AT invented the first American air-to-ground radio transmitter. They tested this device at Langley Field in Virginia and found it was a viable technology. In May 1917, General George Squier of the U.S. Army Signal Corps contacted AT to develop an air-to-ground radio with a range of 2,000 yards.

Why do pilots say super?

Pilots of “heavy” and “super” aircraft are required to announce their category at the end of their call sign. This helps ATC and reminds everyone that these airplanes need more space than other categories.
