How does 5G affect radar altimeter?
Radar altimeter interference from 5G signals can take the form of loss of radar altitude information or, worse, incorrect radar altitude information unknowingly being generated. There have been fatal accidents associated with incorrect radar altitude, most recently Turkish Airlines Flight 1951 in Amsterdam in 2009. Understand the risks. High-powered 5G signals can interfere with low range radio altimeter functionality in aircraft. This interference could result in misleading altitude information going to the pilot, potentially creating a very dangerous situation.People in the know said aviation agencies in India had objected to rollout of 5G near airports due to aviation safety reasons. A radio altimeter giving a wrong reading can even lead to a crash.While it is very unlikely that exposure to the 5G radiofrequency (independent of mobile phone use) will cause cancer, many people worry that mobile phone use will. However, there is little evidence to suggest there is a problem.
Where may a radar altimeter be inaccurate?
Another issue with radar altimeters (without a baro altimeter) is that the ground isn’t flat and if an airport is in valley or on a hill it would give the pilot an inaccurate representation of their position relative to the runway. Radar altimeter interference from 5G signals can take the form of loss of radar altitude information or, worse, incorrect radar altitude information unknowingly being generated.
