Apparently the US is using different frequencies for 5G than other countries and this is causing problems with aircraft altimeters.
"The UK flag carrier [BA] said it had grounded “a handful” of Boeing 777 services after it emerged that 5G signals could interfere with radio altimeters, the cockpit instrument that measures aircraft height."
"American 5G networks operate on a radio frequency close to those used by aircraft altimeters. In the UK and Europe, 5G uses a lower frequency less likely to interfere with cockpit instruments."
"Sir Tim Clark [The British boss of Middle East carrier Emirates] said: "I need to be as candid as I normally am, and say this is one of the most delinquent, utterly irresponsible issues, subjects I've seen in my aviation career..."
Why must the USA yet again set its own non compatible standards?
