Mechanically actuated

Question 4

How are the ailerons and rudder actuated?

Answer 4

Hydraulically but with mechanical backup

Question 5

What do the 4 tabs on the elevator do?

Answer 5

2 outer (servo) - reduces the control forces required by proportionally deflecting in the  opposite direction to the elevator
2 inner (spring) - inactive at low speed but reduces control forces at high speeds

Question 6

If one set of elevator controls become blocked, what can be done?

Answer 6

One can be disconnected and use the other set of mechanical controls

Question 7

How can pitch trim be commanded?

Answer 7

Mechanically through switches on control wheel
Back up switch in centre
Automatically through autopilot or speed brake actuation

Question 8

What happens if only one trim switch is held for >7s?

Answer 8

The system assumes that switch is inop and disregards further inputs

Question 13

Yaw control protection is active above what speed and what system is shut-off?

Answer 13

Question 14

What is the +/- rudder deflection limit in the air or on ground

Answer 14

+/- 15°

Question 15

What 3 conditions must be met simultaneously for the rudder hard over protection to kick-in?

Answer 15

Deflected beyond 5° +/- 1° AND
Force greater than 130lbs on pedal to counteract rudder deflection AND
Both engines N2 >56.4%

Question 16

What type of flaps are on the barbie jet?

Answer 19

2
1 inboard
1 outboard

Question 20

What conditions must be met to deploy air speed brake

Answer 20

TLA <50°

Flap 0 or 9°

Question 21

When are ground spoilers auto enabled

Answer 21

Wow + Wheel speed > 25kts + TLA < 30 degrees or N2 < 50%

Question 22

When the speedbrake is comanded, what system provide auto pitch trim?

Answer 22
