We'll know in 30 years when it's released under the freedom of information and privacy act...

Yeah, Boeing has a nice system. Ailerons deflect first, then at certain point you get spoilers deflecting progressively on one wing to help you roll. In the case of spoilers already being up (use of speedbrakes to descend, for instance), you get differential spoilers with one side lowering progressively.

Works good, lasts a long time.

Rip if you can pull up some drawings on Monday and compare them to the pic that would rock.

Also if you can find a schematic of the flap/slat system, showing PDU, torque tubes, gearboxes, actuators, brakes, sensors, etc, that would rock.

Rgr Mr. Toad. I did a B737 flight on Thursday, and noticed the spoilers deflecting to assist the ailerons - on the take off roll! I doubt that the intention was to kill lift at that stage of the flight. AKWeav?!

No, you don't want the spoilers up on T/O roll. Did it stay like that a long time? Or was it momentary like he was just late with his control check?

Yep, just momentary - and not a full deflection.

There's some guys that have a habit of "stirring the soup" right before takeoff. They move the controls to the stops to make sure nothing is binding and all is right with the world. In the checklist it's the control check but it's usually done during taxi out.

No, I don't think it was that. We were about half way into the take off roll, and it was one of those English days when the wind was in several different directions. Hehe, we get plenty of those.

Hell, I wouldn't even know where to start for specific details. Give me a tooling number, then I can find it.

We made the tools that made the parts, that means higher tolerances (.003 in some cases, generally +/- .010 though, production parts were held to a .030 tolerance.)
