Flashcards in Secondary Flight Controls Deck (21):
What are the secondary flight controls?
Hydraulically actuated spoilers, horizontal stabilizer, flaps
When the adjustable horizontal stabilizer is trimmed properly, what is the position of the control column?
The stabilizer trim is measured in the cockpit as _____ to _____ units of trim.
-3 to 11
How can you move the stabilizer?
Electrically, manually, or through the autopilot.
During preflight, what is the correct setting of the stabilizer trim prior to checking the elevator?
6 to 11 nose-up
The left_____ switch and the right______ switch when pressed simultaneously, move the horizontal stab leading edge at a rate of _____________.
Clutch; motor; ½ degree per second
The _____________ flaps determine the deflection of the leading edge flaps.
The warning horn sounds if the No. 3 throttle is near OPEN and the flap lever is near the ________ detent.
0, 40 or 50
When will the warning horn sound on the ground?
No 3 throttle near fully open and: speed brake is aft of 2 degrees, leading edge flaps not fully extended and flaps lever is 0, 40 or 50 degrees
Only the _______ flaps can be manually extended or retracted
After an unscheduled rudder deflection, one of the first steps is to determine whether the rudder pedals moved. What does this step determine?
Whether the potential cause of the problem is Power Control Unit (PCU)/mechanical (rudder pedals moved), powered rudder, or EFAS/SYD (did not move rudder pedals)
Maximum available spoiler deflection using the speed brake lever is _______ degrees.
A speed brake lever position of less than ________ degrees is not recommended due to a tendency to overcontrol at these settings.
If EFAS is inoperative, Vmcg can increase by as much as _______ KIAS
If you experience an unscheduled rudder deflection, after S1, you should immediately:
Turn off the rudder power
The inboard elevator tabs improve control characteristics by reducing the tendency to ___________at higher speeds.
Prior to performing the Flap and Speed Brake Warning Horn check, ensure the _______ are fully extended.
Leading edge flaps
After an unscheduled rudder deflection, EFAS and SYD turn off as a direct result of:
Turning off the rudder power (remember when pressure drops below 1,000 PSI, EFAS/SYD turn off
After turning off the rudder power due to an unscheduled rudder deflection, check _______ bleeds down, _____ disengages, and the ______ disengages.
Rudder power hydraulic pressure bleeds down, EFAS/SYD
If the rudder pedals didn’t move during an unscheduled rudder deflection, what is the possible cause?
