Morning all,
Im getting myself confused with CAT III minima. In my ATPL books i have found numerous references to the legal minima but they differ.
CAT IIIa - DH less than 100' or no DH (in Ace the tech. pilot int it says 50') and 200m
CAT IIIb - DH less than 50' or no DH and less than 200m but more than 75m
CAT IIIc - (never used commercially) No DH and No RVR
Now forgive me for being silly but arnt the IIIa/b a little similar. as you could be operating IIIb with a DH of 75' but you could also be operating IIIa
is it the RVR that is the deciding factor.
Many thanks
Nick
