Airline passengers who have endured tens of thousands of weather-related flight delays this week could face a new source of disruptions starting Saturday, when wireless providers are expected to power up new 5G systems near major airports.
Aviation groups have warned for years that 5G signals could interfere with aircraft equipment, especially devices using radio waves to measure distance above the ground and which are critical when planes land in low visibility.
Transportation Secretary Pete Buttigieg recently told airlines that flights could be disrupted because a small portion of the nation’s fleet has not been upgraded to protect against radio interference. The airline does not expect to cancel any flights because of the issue, Delta said Friday. The airline plans to route the 190 planes carefully to limit the risk of canceling flights or forcing planes to divert away from airports where visibility is low because of fog or low clouds.
Wireless carriers including Verizon and AT&T use a part of the radio spectrum called C-Band, which is close to frequencies used by radio altimeters, for their new 5G service. The Federal Communications Commission granted them licenses for the C-Band spectrum and dismissed any risk of interference, saying there was ample buffer between C-Band and altimeter frequencies.
