Fault Found In Honeywell Avionics

The Federal Aviation Administration (FAA) has issued an Airworthiness Directive (AD) relating to a recently discovered flaw in Honeywell Avionics used on the following models of Boeing aircraft:


-Boeing 737-600, -700, -700C, -800, -900, -900ER
-Boeing 777 (All variants)


Various tests have found that certain WiFi signals (along with weather radar, satellite and mobile/cell phone signals) have created interference on all display units. This includes the crucial Primary Flight Display (PFD), Multi-Function Display (MFD) and Engine-Indicating and Crew-Alerting System (EICAS) which are all needed for the pilots to control and manage most aircraft systems.

The FAA have advised all airlines that operate the above aircraft to change, upgrade or modify all Honeywell avionic systems. However, boss of Irish low-cost carrier Ryanair, Michael O'Leary has said that the changes are not necessary and highly cost-draining to the airline (which operates 301 Boeing 737-800 aircraft.) Honeywell suggested that only aircraft where the aircrew and passengers use WiFi-enabled tablets and other devices should be made to update their equipment.

I think it's a bit unnecessary for airlines to replace their avionics if they don't operate WiFi (that means, very rarely, I agree with O'Leary Undecided Tongue)

Apparently it'll cost $10,370 to replace each system; that's $4,967,230 for Southwest and $3,121,370 for Ryanair. $1.32 million for Delta, $601,460 for British Airways and $1.35 million for Emirates (who operate 130 777s)


European carriers probably need to think about this article if they don't want to change their systems.
