Having flown that magnificient beast, I'll tell you that the BUFF (Big Ugly Fat FVCK) does NOT have ailerons. The B52D was the last aircraft to have ailerons. I believe.
The spoilers on the G and H models are more than enough for control, even for precision manuevers like air refueling or MITO's (Min Interval Takeoffs/12 sec spacing). On approach, we set the Spoilers (we call them Airbrakes) to position 4. (4 out of 6 positions) This increases the roll response on approach.
The flaps on a B52 are deployed simply UP or 100% down. Except for engine out, where we use 40% Flaps. When we call for flap extention it can be pretty disorienting because of we go from UP to 100% down. This results in a hugh attitude and trim change. We try to extend them during a descent to minimize altitude deviations. The flaps want to pitch the aircraft up and it helps to have the throttles at idle.
The plane still looks great. They were already 30 years old when I was flying them back in the 1980's. They no longer have a gunner or a navigator, I'm told, since you need complete air superiority to or standoff munitions to employ them. Great bomber, 51-500 pound bombs! Amazingly. There I go getting all teary eyed again. My love affair with Boeing, began with this airplane.
