FAA Issues New 5G Interference Airworthiness Directives
New FAA rules would prohibit certain aircraft operations where 5G interference is encountered or likely.

The FAA today announced two new airworthiness directives (ADs)—one covering transport and commuter-category airplanes and the other directed at helicopters—that address the threat of potential radar altimeter interference from 5G cellular in the 3.7 to 3.98-GHz frequency (C-band). The ADs require insertions into the limitations sections of aircraft and rotorcraft flight manuals (A/RFMs) that will limit flight operations when such interference is encountered.
