|
During cruise to prevent uncommanded motion what does the FSEU do? |
The FSEU maintains pressure on the retract lines and depressurizes the extend and full extend lines |
|
To complete the STALL WARNING TEST, how long must AC transfer busses be powered for? |
4 minutes |
|
Explain the LE Devices panel on the overhead panel |
Yellow - transit Green - LE flaps fully extended, LE Slats in extend Green - LE Slats fully extended position Test - illuminates lights |
|
When the STBY RUD ON light illuminates what has happened? |
The SRSOV (standby rudder SOV) has successfully opened. Usually when the Standby pump has been activated manually or automatically |
|
Does the alternate flaps system extend TE flaps? If so what is different about how the TE flaps are extended VS leading edge devices? |
TE flaps are extended using seperate electrical motor where the LE Devices are extended using the standby Hydraulic motor. Both are controlled using the same switch. LE devices will go to the fully extended position |
|
Is there a speed restriction when using the Alternate flaps? |
Yes, 230 knots (placarded below the gear) |
