Reports suggest that the US will not delay a deadline for aircraft to incorporate sensors to detect possible 5G interference.
The US Transport Secretary Pete Buttigieg has confirmed that airlines were told the 1 July deadline would not be changed despite some airlines warning they will not be able to meet the deadline.
5G rollout in the USA has been delayed to allow airlines to incorporate sensors in their aircraft.
The American Federal Aviation Administration (FAA) has been concerned that the C-Band spectrum which 5G wireless operates on could interfere with aircraft altimeters, which help pilots determine how far above the ground their planes are.
