If the speed brake lever is not armed for the spoiler deployment, what will the spoiler do on landing?

Answer 17

Only deploy automatically if reverse thrust is used

Question 18

Which hydraulic systems power stabiliser trim?

Answer 18

Left and centre

Question 19

Which hydraulic system operates the flaps?

Answer 19

Centre

Question 20

What maybe indicated when the aileron lockout light comes on while accelerating?

Answer 20

One or both of the outboard ailerons failed to lock out

Question 21

Why should the speed brake lever be moved from ARMED to the DOWN detent if the AUTO SPDBRK light illuminates?

Answer 21

To prevent inadvertent speed brake extension in flight. Speed brakes must be manually deployed upon landing

Question 22

What is the function of the rudder ratio system?

Answer 22

Decreases maximum rudder pedal inputs from the pilot to reduce rudder deflection with increasing air speed

Answer 28

25

Question 29

What is indicated by the UNSCHED STAB TRIM light?

Answer 29

Answer 32

Move the control column in the opposite trim direction

Question 33

What does the RUDDER RATIO light illuminated in-flight mean?

Answer 33
