Aircraft radar altimeters operate within 4.2–4.4 GHz , the lower half of which falls within the C-Band—a frequency range from 3.7–4.2 GHz where the combination of the range of signal transmissions and capacity are optimum.

Signals emanating from a nationwide forest of 5G cellular towers set for activation in the U.S. this week could interfere with radar altimeters , potentially causing them to report wildly inaccurate measurements of an aircraft’s height above the ground, aviation experts are warning.
Read moreWho uses radar altimeters?
A related use of radar altimeter technology is terrain-following radar, which allows fighter bombers to fly at very low altitudes. The F-111s of the Royal Australian Air Force and the U.S. Air Force have a forward-looking, terrain-following radar (TFR) system connected via digital computer to their automatic pilots.

The Federal Aviation Administration has said 5G networks could disrupt aircraft operations. The main concern is that cellular towers and antennas near airports could interfere with radio altimeters , which are electronic devices in aircraft that help pilots gauge their altitude above the terrain.

There is a major risk that 5G telecommunications systems in the 3.7–3.98 GHz band will cause harmful interference to radar altimeters on all types of civil aircraft—including commercial transport airplanes; business, regional, and general aviation airplanes; and both transport and general aviation helicopters.
