 3. Operation of the TE Flap System
_______________________________
 A. General
 (1)  During normal hydraulic operation, the TE flaps and LE slats move by the operation of the flap control lever.
 During alternate electric operation, the TE flaps can move independently of the LE slats. If you arm the flap and slat alternate drives, you can control the TE flaps and the LE slats with the position selector switch for the flap/slat alternate drive. If you arm only the flap alternate drive, you can control only the movement of the TE flaps.
