Ok here is a question. I am well versed in the derived alternate method of figuring out weather minimums for alternates. (one nav aid two nav aid)
One nav aid available, add 400' and 1mile
Two independent nav aids you add 200' and 1/2mile to the highest one
My question is how does non-standard alternate minimums affect deriving these alternate minimums? If OpSec CO55 ignores standard alternate minimums in the first place how does it interpret non-standard minimums?
For example the approach chat has an "A" in a triangle so you look up the non-standard alternate minimums. For the ILS it states Cat. A,B,C,D requires a minimum of 800-2 to be used as an alternate.
Does this mean you use that 800-2 or do you still add 400-1 to that figure for your derived alternate?
Thanks
