Airworthiness Directives; Transport and Commuter Category Airplanes

A node in the IdeaNavigator AI intelligence graph with 3 connections across 3 reports.

The FAA is adopting a new airworthiness directive (AD) for all transport and commuter category airplanes equipped with a radio (also known as radar) altimeter. This AD was prompted by the determination that radio altimeters cannot be relied upon to perform their intended function if they experience interference from wireless broadband operations in the 3.7-3.98 GHz frequency band (5G Lower C-Band) summary
