The FAA’s new airworthiness directive for Airbus and Boeing jets and G5 interference

The FAA on Jan. 25 published an airworthiness directive on the Boeing 777 and 747-8 airplanes that interference may affect multiple airplane systems using radio altimeter data. The directive does not prevent any operations at nearly all large U.S. airports. The FAA has approved alternative means of compliance for the airplanes.

Airplane models with cleared altimeters include all Boeing 717, 737, 747, 757, 767, 777, 787 MD-10/-11; Airbus (AIR.PA) A300, A310, A319, A220, A320, A321, A330, A340, A350, A380; Embraer (EMBR3.SA) 120, 170, and 190 regional jets; All CL-600/CRJ regional jets; DHC-8 and ATR turboprops.

The U.S. Federal Aviation Administration (FAA) on Jan. 25 also issued approvals for additional altimeters that allow about 90% of the U.S. commercial aviation fleet to perform low-visibility landings at airports where 5G wireless is deployed.
