1. Tristar. On selecting land flap(switch is on the lever not the flap so you may not actualy have it.) The inboard 4 spoiler panels move out to a 9degree null position. From there they respond to pitch inputs along with the stab(all flying tailplain)to increase or decrease the rate of descent without changing the pitch attitude. Developed to reduce "longitudinal scatter" ie. make the aircraft touchdown at the same place on the runway.
2 Tristar-500. The outbard ailerons have 3 active modes to reduce wing bending fatigue.
a. High Lift mode. With flap selected both outboard ailerons move to a 6 degree up position thus offloading the outboard section of the wing.
b. Elastic mode suppression. G meters in the wing tips and body compare singnals and cause each aileron seperately to move in oposition to the bending force thus smoothing out individual wing flexing.
c. Donīt remember the name. Similar to b but both ailerons work in unison thus smoothing wing root flexing and giving a smoother ride in turb.
The whole lot was developed because the 500 has extensions to the wing tips to reduce induced drag.
3. Reduce lift, Increase drag(air), Increase drag(ground), roll assist, DLC, pass
4. 1/2rho vsq uses a Q pot(chamber) to measure air density and cause artificial force(friction) in flying controls.
5 wing sweep.
6 A stall condition that due to aircraft design causes the elevator to fly in disturbed air thus rendering it less or in-efective.
