Gentlemen, back to my original question:
I believe the FAA requires you to use higher minima on a circling approach if you exceed the max speed of your aircraft category.
I have no knowledge of any rule in EASAs world that requires you to use higher minima when exceeding e.g. category C approach speed limits.
Itīs a pure technical question. Any CIRC at minimums might be very challenging or undoable - agreed. Question is which minima do I have to use (legally) on a CIRC approach with e.g. a category C aircraft when I exceed C speed limits?
