Hello again,
No, I have been told that there is a specific requirement, originating from a regulation, that a minimum of 50 feet MUST be added to the published MDA(H), plus any additional SOPs/type specific/operator specific/whatever factor.
Actually, I have seen this with my own eyes but, alas, I can't seem to find it in my (large and messy) document library.
Please realize I am not making this up and I do have operational experience (I am a RW pilot). Also, forgive me if occasionally some of the things I write make no sense (not being a native English speaker can be a pain)...
