The FAA on Wednesday added Seattle-Tacoma International to its list of airports where most large jets are now permitted to land in low visibility without risk of interference from the new 5G wireless networks.
SEATTLE - The Federal Aviation Administration on Wednesday added Seattle-Tacoma International to its list of airports where most large jets are now permitted to land in low visibility without risk of interference from the new 5G wireless networks.
The Radio Technical Commission for Aeronautics, or RTCA, did tests in 2020 that showed a risk of 5G C-Band interference with the altimeters on airliners, business jets, general aviation aircraft and helicopters. Over FAA objections, the Federal Communications Commission outright rejected the RTCA report.
In addition to Sea-Tac, the list now includes the major West Coast hub airports in Los Angeles and San Francisco as well as Dallas, Chicago, Portland and Salt Lake City. And the list doesn’t include Boeing’s 787 Dreamliner, even though the altimeter model supplied by Honeywell for the entire fleet of 787s is one of those that has been cleared. The FAA issued a separate Airworthiness Directive imposing restrictions on 787 operations at airports with 5G deployed.
