I think it's that.
so i just need to add one category.
let say i can land cat2, but minimum weather must be good for cat1 (200ft/550RVR).
if i can land only Cat1, i will use minimum weather for a VOR approach.
in this case i can file the airport as alternate?
but I can still land the way I want?this is only for planning?.
the numbers I got in my first post are FAA rules.
