American wireless carriers are set to start running higher-power 5G networks around U.S. airports on July 1, despite concerns over interference with airplanes’ altimeters. This comes after delays in launching the networks last year, as carriers sought more time to address the problem.
Transportation Secretary Pete Buttigieg recently warned that airlines who haven’t upgraded their planes’ equipment to avoid the interference by July 1 could face flight delays. Buttigieg noted that more than 80% of the domestic fleet serving U.S. airports has been retrofitted, but many aircraft operated by foreign air carriers are still awaiting retrofit.
Altitude measurement is essential for flights on low-visibility days, and only planes with retrofitted altimeters will be able to perform low-visibility landings. Buttigieg urged Airlines for America, an industry group that lobbies for carriers, to ensure that passengers are not left stranded due to delays or cancellations on such days.
With just months left before the deadline, airlines need to take swift action to upgrade their equipment, or risk facing disruptions that could upset passengers and hurt their reputation.
