-HDG - ADIRU heading data is gone
-WXR FAIL - weather radar system failure
-PWS FAIL - weather radar R/T predictive windshear
failure
-TERR FAIL - GPWS terrain function failure
-DME 1/2 - DME interrogator failure
-ADF 1/2 - ADF receiver failure (shows only when you
select ADF on the EFIS control panel)
-VOR 1/2 - VOR receiver failure (shows only when you
select VOR on the EFIS control panel).
