Ok..then I definitely misunderstood something here. Just to make sure that I understood it correct now.
Precision Approaches (e.g. ILS):
DA/DH is used
Minima can be underflown slightly
Named Height (below 200feet; usually for Cat II and III)
Named Altitude (above 200 feet; usually Cat I)
Non Precision Approaches (e.g. RNAV, VOR, NDB):
MDA/MDH is used
Minima can not be underflown!
Named Height (below 200feet)
Named Altitude (above 200 feet)
One question....if the set minimum is 150feet (either DH or MDH) will the "minimums" call out come from the radio altimeter measurement?
And if the set minimum is 300 feet will the callout come from the barometric altimeter?
Or will it always be the barometric altimeter, which is responsible for minimums callout?
Thank you!
