CATlll "Fail Passive" approach
I'm looking at this statement and having trouble with the accuaracy. (B777)
If the NO LAND 3 message appears before the LAND 3 is annunciated on the PFD, it is an Advisory message. The aircrew should anticipate a LAND 2 fail passive approach and should adjust minimums accordingly. The minimums for a fail passive Category lll approach are typically set to a 50 foot Decision Height (DH) on the radio altimeter.
If anything I would imagine restting the RA upwards to say 100'?
What do make of this? Maybe I'm having a problem wrapping my head
around the CATlll "Fail Passive" concept. Seems like if you had aLAND 2 showing you would simply move up to CATll mins?
