got unemployed a couple of month ago, my girlfriend on a long holiday to visit her parents, my best friends busy getting themselves a girlfriend.......so
........plenty of time to have fun with 737 sys!!!!
Anyway,I need to have the ALTERNATE FLAP MASTER SWITCH on ARM to use the Alternate flap pos switch to retract the TE flaps.From AOM:
The guarded ALTERNATE FLAPS master switch closes a flap bypass
valve to prevent hydraulic lock of the flap drive unit and arms the ALTERNATE FLAPS position switch. The ALTERNATE FLAPS position switch controls an electric motor that extends or retracts the TE flaps.
After Alternate flap retraction I will find myself with LE devices full ext...so if you place the ALTERNATE FLAP MASTER SWITCH on OFF will the PTU help you with the LE devices?
Thanks a lot for helping me sleeping well tonight!!!
