Control wheel - spoilers jammed how can you control

Captain uses control from ailerons

If only ailerons or spoilers work what happens to control

Will rate reduced - at least 10 degrees from FO to initiate spoiler movement

Spoiler deployment SPF

All spoilers deploy to 60degrees
Non SFP - flt spoilers at 33-38 and gnd spoilers at 52

Flap load relief how does it work

Flaps auto raise if speed limit exceeded (leaver doesn’t move but gauge shows change)

Q feel -

Hyd a and b and dynamic pressure sensed by elevator and then vary control pressure to regulate feel

Perfectly

Stall management yaw damper?

Gives false q feel near stall to make it hard to pull back on controls

FEEL DIFF PRESSURE light

Comes on after 30’ seconds of diff pressure between A and B of over 25%

How well did you know this?

Not at all

Perfectly

When are you likely to see feel diff pressure

MC after elec 1 pump on and elec 2 is off without NWS pin

Speed trim system

Low gross weight with aft CG and high thrust, get auto trim to stay spd stable

Speed trim and Mach trim controlled by what computer

AP FCC

When does electric and AP speed trim change

Flap not up - hi speed Flap up - low speed

Manual and electric trim ranges

Manual uses larger range

Elevator trim with ap in does what?

Disconnects AP

Does rudder trim and YD make pedals move

Rudder yes - yaw damp no

Flap aysym

Flap at fault doesn’t move and needles split

Flap skew

Side at fault needle goes in opposite direction of flap leaver movement

Spd brake load alleviation

If beyond 50% moves it back automatically

Spoilers on RTO -

When selected or automatically on selection of REV

Move TL with spoilers deployed on gnd

Stows spoilers automatically

Alt flap selection Lims

Any movement needs 15 seconds Full cycle 5 mins

LE with alt flaps

Fully extend - can’t be raised

Auto slat effect on LE

If LE slats extended and you approach stall they fully extend

Autoslat SFP vs normal

1-25 on SFP 1-5 on normal

Main rudder PCU authority >135 kts

Reduces pressure by 25%

Sby yaw damper active?

With hyd a and b fail and on sby system

If A or B fails is there any control degradation?

No degradation (half the spoilers roll effected?)

LE FLAP TRANSIT Amber until when on alt flap selection

when TE reaches: SPF - 15 deg Non SPF 10 deg

Total Hyd failure effect on spoilers -

No spoilers - nothing do do with reversion or control jam logic with capt and fo

Aileron trim switch is where

Aft electronics panel

Force flight monitor ?

If a and b give different pressures/malfunctioning - detects this and transfers to sby rudder

FLT CONTROL - OFF

Isolates primary controls via cut off valve Does not effect sby pump

ALT flap to arm -

Closes TE bypass valve - activated Stby pump and arms alt flap swx

Forget to arm SPD brk leaver GND spoilers will deploy

Wheel speed +60 Idle trust Using reversers

Flt spoilers I’d you move leaver past flight detent -

Won’t go past it

Alt flaps use what motor

Aysymetry protection is on which flaps

Trailing edge not leading edge

Skew protection is on which flaps?

Trailing edge and LE slats

Protection for improper position

LE only Get LE FLAP TRANSIT light

Protection for uncommanded motion

Le and te devices

SPD BRK DO NOT ARM LIFGT

Abnormal condition Test imput Below 60kts and leaver not down

SPD BRK EXTENDED LIGHT

Extended in landing config below 800ft

LE TRANSIT LIFGT IS INHIBITED

during auto slat ops

Do the pitch trims for AP and electric use different motors

How many gnd spoilers per wing
