a real giant p
1. ailerons
2. rudder
3. elevators
4. autopilot A
5. landing gear
6. ground spoilers
7. inboard flight spoilers

Front 12

b hyd sys powers:

size of reservoir

cooled by:

Back 12

a real toy baatl
1. ailerons
2. rudder
3. elevators
4. autopilot b
5. landing gear transfer unit
6. trailing edge flaps

Front 13

b hyd sys loss and lose what sys:

Back 13

a toy baat
1. autoslats
2. trailing edge flaps
3. outboard spoilers
4. yaw damper
5. brakes (normal)
6. autopilot B
7. thrust reverser

Front 14

force flight monitor: what does it do?

Back 14

detects opposing pressure from a & b sys to rudder which could happen if a or b input is jammed or disconnected from rudder. will auto turn on stby hyd and pwr rudder.

Front 15

autoslats:
when work?

Back 15

move slats from extend to full extend prior to stick shaker ... when t.e. flaps are at 1-5 degrees

Front 16

what powers autoslats?

Back 16

sys B unless sys B pressure is low, then PTU

note: slat/flap skew detection is inop during autoslat deployment

Front 17

what is powered when you move flt control switches to STBY?

Back 17

rudder & thrust reversers

Front 18

if both flt control switches are moved to STBY, what happens to aileron and elevator control?

Back 18

manual reversion

Front 19

what happens when alt flap master switch is moved to down pos?

Back 19

1. T.E. flaps electrically move down (can be moved back up)
2. Leading edge devices moved to full down pos hydraulically (cannot be moved back up)

Front 20

when is hyd q RF indication valid?

Back 20

1. a/c on ground w/ both engines shutdown OR
2. after ldg w/ flaps up during taxi-in
