What occurs to me folks is that it is the pilot who is in command of the aircraft and it is therefore the pilot who chooses which runway to use for both landing and t/o. Now if the airport declares via notam that the runway is closed then that is quite different. If however the runway you are to use gives an unsafe approach or landing then this should be refused by all a/c whether private or CAT. In the event of an accident caused by such an unsafe attempt to use the "incorrect" runway, who is liable? The commander or the airport? Any one with better knowledge please let us have your views. Of course the airport I assume can refuse you permission to land at all but if permission has been granted can it then be conditional on an unsafe approach?
