suggest you may find that a 4eng aircraft departing on three with no pax or bags may well be higher over the upwind boundary than you would expect and since it`s a standard positioning procedure why would you want to be met by fire crews? . . . also suggest that with the loss of a second donk the only real danger may be inthe event of a go-around if hot,high and heavy.
. . . mind you if the other 2 packed up you`d be up there all day !
