If I recall (others, help me out, please), you needed to be clean and have 200 KIAS. Then, you would be able to fly.
That is what I recall as well, with the possible exception that in the 200 series you might need 210 knots.
Depending on whether you had engine hydraulics or not, the commit point for landing was flap extension or gear extension.
Yes, if you had to manually extend the gear you were committed to landing at that point. One day just playing around after finishing a recurrency course the sim instructor had me try to go around on one engine with the gear down just for the hell of it. We made it a lot farther that I thought we would, of course the instructor had configured the sim to be an empty aircraft with only about 15,000 pounds of fuel.
However, I DO remember that flying the 727 with only one turning was a required maneuver in the simulator to obtain the type rating.
That is correct, at least it was with me. I started off with a V-1 cut, normal two engine climb out, return for an ILS to minimums, a miss due the old lost fuel truck on the runway and the second engine failure just after the gear and flaps were retracted. In my case the second engine failure was an uncontrollable engine fire. However, miraculously the weater suddenly became clear and the single engine approach and landing was visual.
I sure liked flying 727s, miss em.
411A, I never had the pleasure to fly the L1011, however, every person that I have talked to that have flown them loved them, must be a hell of an aircraft.
