26
What powers flight control trimming?
Essential 28V DC
27
If you have a roll trim runaway, what can you do?
Press ROLL MOTOR CONTROL switch to OFF
28
If ROLL MOTOR CONTROL switch is OFF, where does the input go to instead of the roll trim motor?
Direct to FCC
29
What is the maximum rudder trim movement either side of centre?
19 degrees
30
Will rudder pedals move with rudder trim input?
No
31
How do you centre the rudder trim within 5 seconds?
AUTO CENTER button
32
Which spoilers are used for roll augmentation in normal augmentation?
Mid and outboard
33
Which spoilers are used in EB mode?
Outboard only
34
What is full spoiler range of movement?
55 degrees trailing edge up
35
What degree of spoiler deployment do we get for speed brake in flight?
30 degree trailing edge up
36
An EHSA has how many LVDT’s? Where do they report to?
- 1 | - the REU
37
An EBHA has how many LVDT’s? Where do they report to?
- 2 - one reports to the REU - one reports to the MCE
38
What will happen when I moved the speed brake handle out of the detent above 90% throttle?
- Speed brake auto retract | - AMBER CAS message
39
When do you get a red GROUND SPOILER CAS message?
When all auto deploy conditions are true but the spoilers are not commanded to deploy
40
What are the ground spoiler auto arming requirements?
- ground spoiler switch ARM - throttles at idle - L&R WOW on ground - flaps 39 - wheel speed >47 knots
41
What does elevator offload do?
Removes load from elevator during pitch trim
42
What do CLAWS do?
Prevent movement outside of safe flight parameters for current aircraft configuration
43
Whilst the REU’s report and receive information from the FCC, the MCE’s only _______ information
Receive
44
The elevator stand alone LVDT reports to the EHSA. What is the reason for this stand alone LVDT?
Redundancy. Pitch control is critical
45
How many CMA’s are there in total?
- 3 - pilot and copilot (both do pitch and roll) - rudder
46
What is max degree of spoiler deployment for roll assist?
55 degrees
47
How do you deploy speed brakes if auto deployment doesn’t happen?
Speed brake handle
48

8 torque tubes
54
How many pillow blocks connect the flap rods in each wing flap well? What do they compensate for?
- 6 | - wing flex
55
Why does flap handle gate switch #1 report to the BFCU?
For high and low speed gain CLAWS
56
What do you have to do if you find flap PDU ecology bottle 50% full on a preflight?
Empty and check after next flight
57
What does the flap actuator no back function do?
Prevents unwanted retraction
58
Where is the flap no back function located?
Internal to actuator. Must replace actuator if fault found
59
What trim switch do you use when rigging the stab?
Back up trim switch

Off
64
How many position resolvers provide HSTA position to the HSCU?
2
65
What can you do if the HSTA no back brake is US?
Change the actuator. Internal to the actuator so no action possible
