Extending a leading edge slat will have what effect on the angle of attack of a wing?
•  Increase the angle of attack.
•  Decrease the angle of attack.
•  No effect on angle of attack.

Tommibona asking:
•  The effect of the slat is to prolong the lift curve by delaying the
stall until a higher angle of attack. how does it possible that the angle of attack decreases?
