Question 14

What does illumination of the ELEVATOR TRIM SHUT OFF Switchlight indicate?

Answer 14

Trim-runaway

Question 15

As well as moving the Flaps, what is the effect of moving the Flap selector from 0 deg to 5 deg?

Answer 15

Removes the +/- 12 Rudder restriction, PTU and SPU come on if park brake off

How could a FLAP POWER Caution be inadvertently generated in the ground?

Answer 16

Flap selection before HYD power

Question 17

When do the Stall Protection Modules act independently and when do they act together?

Answer 17

Independently to activate stick shakers, but must act together to activate the stick pusher.

Question 18

What other systems are affected by the activation of a stick shaker?

Answer 18

AP disengaged and GPWS Pull Up Audio is inhibited

Question 19

Under what Flight conditions would the Stick Pusher be inhibited?

Answer 19

CAS > 215kts, Rad Alt

Question 20

What would you see during a successful test of the stall warning system?

Answer 27

158kts

Question 28

What do the ELEVATOR FEEL, PITCH TRIM, SPLR OUTBD & RUD CTRL Cautions have in common?

Answer 28

All these systems receive IAS information from ADC and are disabled in the event of a IAS mismatch.

Question 29

What is the effect of pushing one of the SPLR or RUD (PUSH OFF) Switchlights on the Glareshield?

Answer 29

Hydraulic Control Pressure to the Spoiler Extend part of the effected actuator is removed
