Airlines cancel some US flights over 5G concerns

Aviation watchdog says signals from 5G masts near airports could interfere with some planes' equipment

Airlines including Emirates, Lufthansa and Air India have cancelled or changed US-bound flights owing to concerns about the deployment of 5G mobile phone technology near airports.

The US aviation watchdog has said 5G signals could interfere with radio altimeters, which measure how high a plane is in the sky and are a crucial piece of equipment for pilots, particularly when landing in bad weather.
