The spoilers should be on the AUTO position I think, or to be extended manually. RTO on the Auto-Brakes, it's just as RJB said, it engages the brakes, wheel brakes that is.
No. Let's try to get this all cleared up so there isn't so much guessing going on.
First, the spoilers and the autobrakes are two totally seperate systems.
Spoilers- If there is an armed/takeoff position they will normally be in that position for takeoff. If, during the takeoff roll, the thrust levers are reduced to a predetermind position on the quadrant, the spoilers will deploy. If the spoilers are armed for takeoff they can still be deployed manually. In most airplanes that means pushing the spoiler handle down (out of the armed position), pulling it back and then locking it in position by pulling the handle up (spoilers deployed). It may work a little differently on different airplanes, but you get the idea.
Autobrakes- Some have a takeoff postion, some don't. If there is a takeoff position the autobrakes will normally be in that position for takeoff. In the MD-11 that position is simply labeled TO. If, during the takeoff roll, the captain decides to execute a rejected takeoff (RTO) the brakes will automatically activate to their maximum stopping capability (max brakes).
If a RTO is done and the airplane is so equipped, both autobrakes and autospoilers come into play. But they aren't a common system nor do they activate via the same inputs. At least not on what I've flown. But as I've said many times, I'm not a Bus driver. And they might be a whole lot different on the Busses.
