why don't we sort the wheat from the chaff and forget about noise abatement! it was not brought up in the original argument....tommie's argument is based on his belief that the airplane will climb at a better angle with flaps up, and thus he believes that one will clear obstacles by a better margin with OEI if the airplane is cleaned early while both engines are operating, and before one of them quits.
there are a lot of self proclaimed experts here who seem to differ, but as far as I can see nobody has yet disproved the central premise that he is putting forward.....will it make a better angle with flaps in the take off position with OEI?
my gut feeling is that it will not....irrespective of the conditions, but i'll check my AFM tomorrow.
