str12: But wot about glide clear? Thar's an awful lot of houses below the route you mention.
In general, if you ask for a clearance, and the route would bust an air law, would you expect the controller to say "no, you can't, don't be silly"?
It is of course the a/c commander who's responsible for everything, I just wonder if a controller would query the legality of a transit in a single.
