In the 727, the spoilers come up after the yoke is rotated 10 degrees. In the 747 for dummies manual I've got with me, it doesn't give a number, it just says the ailerons and spoilers work together for roll control. Hey, if it's not in the book, they can't ask about it on the oral.
In most transport airplanes you are limited to a 10 knot tailwind. You're going to change that around to a headwind before the power is even half way set.
