Also referred to as high lift or secondary ﬂight controls, slat & flap electronic control units (SFECUs) enable optimum take-off and landing speeds by increasing wing lift.
The SFECU is installed in the equipment bays in the body of the aircraft
The SFECU controls the slats and flaps (on the wings) utilized during take-offs and landings
Primary purpose of the slats and flaps is to make the area of the wing bigger, thus enabling the aircraft to fly more slowly
The slats and flaps do not make the aircraft fly more slowly, they increase lift which enables the pilot to control the speed
Slats and flaps are extended and retracted, whereas the spoilers are raised and lowered
