Letter of authorisations states the levels permitted right down to 0.3, based on aircraft certification and crew training, but we don't operate anywhere that requires special authorisation.
Wondering, correct, LNAV/VNAV and not LPV.
We do however have two schools of thought regarding how to conduct the approach, aircraft flight manual states set runway elevation plus 50 feet at the start of the approach, but our airline colleagues, set the missed approach altitude, so I'm curious, what do others use?
