cosmiccomet,
dial-a-flap setting on MD-11 is between 10 and 25. You cannot take off with flaps at 0/slats only (or shouldn't be able to providing the config warning system is functioning normally). The dial-a-flap setting is normally set at 25 for t/o and 15 for approach in our company (followed by gates flaps28 and flaps35 or flaps50)
