Flight controls Flashcards
Which spoilers are used for roll?
2-6
On fctrl page, what does amber number on a spoiler mean?
it’s failed and retracted
On fctrl page, what does amber triangle on a spoiler mean?
it’s failed and extended
During rejected t/o, what are the conditions for spoiler deployment? (when armed)
72 kts had been reached, and thrust levers are set to idle
During Landing, what are the conditions for spoiler deployment? (when armed)
thrust levers are set to idle, and both main gears have touched down
During rejected t/o, what are the conditions for spoiler deployment? (when NOT armed)
72 kts had been reached, and one thrust lever set to reverse
During Landing, what are the conditions for spoiler deployment? (when NOT armed)
both main gears are on the ground, and one eng is set to reverse.
What are the five protections available in normal law?
load factor, pitch, high aoa, high speed, high bank angle
What are the load factor limits?
+2.5/-1 clean, +2/0 in any other config
Pitch attitude limits?
30/-15. in low speed reduced to 25 nose up
What happens to the thrust when Alpha Floor is activated?
TOGA thrust is set
When does high speed protection activate?
At or above vmo/mmo
What’s the max bank angle (hands off)
33 degrees
What’s the max bank angle
67 degrees
What’s the max bank angle while in high speed/alpha protection
45 degrees
When is the low energy aural alert available? When is it inhibited?
Available during config 2-full between 100 and 2000 ft. Inhibited by TOGA, alpha floor or gpws inhibited, alternate or direct law, dual RA failure.
Which protection is always available in alternate law?
Load factor protection
Describe the speed tape in normal law
vls, v alpha prot (top of tiger tail), v alpha max (top of solid red)
Describe the speed tape in alternate law
vls, v stall warning (top of barber pole).
Are overspeed and stall warnings available in direct law?
yes
What causes reversion to manual backup mode?
total electrical loss or all five flight computers or loss of both elevators or loss of all ailerons and spoilers
What does the hollow cross indicate on the pfd? (on the ground only)
Combined FO/captain sidestick position)
What does alpha lock do?
Prevents the slats retracting during low speed or high AoA.
What’s the resulting config when conf 1 is selected on the ground?
1+f
What’s the resulting config when conf 1 is selected in air going from 0 to 1
1
What’s the resulting config when conf 1 is selected in air retracting flaps from 2/3 to 1
1+f
What is vfe next? what does it look like on the pfd?
max speed for next flap lever position, amber = sign
What’s indicated by a three quarter amber box around the hydraulic actuator on the fctrl SD?
electrical failure detected by PRIM
How does flap load relief system work?
prevents flaps being extended when the speed is too high. once speed is low enough, the flaps will come out automatically
Flap limiting speeds from flap 1 - full
240, 215, 196, 186, 180
Which protection is always available in alternate law?
load factor protection
