9 - Flight Controls Flashcards
What happens if you get a RUDDER RATIO EICAS warning?
Left hydraulic system rudder actuator automatically depressurizes to provide structural protection for the rudder
(if hydraulic press normal):
- 15 kts XWind limit
- No Autoland
- Avoid abrupt rudder inputs above 160 kts
To avoid buffeting, use of speedbrakes with flaps greater than ___ should be avoided
5
{CBT}
How long does it take from UP to F20 using Alternate Flap system?
3 min
(20 NM)
(flaps/slats move slower if HDG active)
In the ARMED position, when ________ the speedbrake lever is driven aft to the UP position and the spoiler panels are fully extended
landing gear is fully on the ground (not tilted) and the thrust levers are at idle
On the ground, when _______ the speedbrake lever is driven to the up position and spoiler panels are fully extended (armed/not armed)
either reverse thrust lever is moved to the reverse idle detent
The speedbrake lever does not need to be in the ARMED position
The SPEEDBRAKES light illuminates if speedbrakes are extended when radio
altitude is ______ or ______
800 feet or below
the flaps are in landing position
What is the purpose of the yaw damper system?
improve turn coordination and dutchroll damping
What happens when Flaps 1 is selected?
slats move to the midrange position
What happens when Flaps 5 is selected?
TE Flaps move to 5
inboard ailerons droop
slats remain in the midrange position
What happens when Flaps 25 is selected?
TE Flaps move to 25
slats move to fully extended landing position
The flap load relief system protects the flaps from excessive airloads.
If the flap airspeed placard limit is exceeded with the flaps in ___ the flaps automatically
retract to ___
When airspeed is reduced ____
25 or 30
20
flaps automatically re–extend
Alternate mode flap and slat extension is limited procedurally to ____
_____ is not available in the alternate mode

flap load relief
What happens during a LE Slat asymmetry?
Hydraulic power to the slats is automatically shut off
When the hydraulic driven generator is supplying electrical power, hydraulic flow to the slats and flaps is ____ , resulting in ____
reduced
increased slat and flap operating time
What powers the Stab Trim?
L/C
trim rate varies with airspeed
