We've been sufferring from a radio altimeter issue on our ship(long nose) which has had dual RAD ALT systems.
Both systems work properly lower than 2500FT AGL though,....
Sometimes we got the "RAD" miscompare indication or "RAD1" or "RAD2" at around 3000FT AGL or higher. In case of 4500FT AGL or higher, we got a radio altimeter tape on the PFD(either PLT or CPLT side only) suddenly together with the landing gear caution w/audio and EGPWS messages.
Anyone has had the same issue?
Appreciate all the inputs! Thanks.
