FAA Orders Replacement of 737 and 777 Display Units
An FAA airworthiness directive will require the replacement of thousands of Honeywell display units in the cockpits of Boeing 737s and 777s.

The FAA today adopted an airworthiness directive requiring the replacement of Honeywell phase 3 display units (DUs) on 1,326 U.S.-registered Boeing 737 and 777 airliners. The AD, which takes effect November 5, is based on concerns that the data such as airspeed, altitude, pitch and roll, attitude and heading could disappear from the displays due to interference from wireless devices. It requires the phase 3 DUs to be replaced with phase 1, 2 or 3A units, as well as the installation of new DU database software.
