Q

What system does the Standby Rudder use following the loss of Left/Right systems?

A
  • Standby Rudder will use AUX pump to YD1. May need to select FGC1.
  • It uses the AUX pump to power the Rudder through the Left systems port and only works while airborne (WOW in FLIGHT)

Q

How are the Flaps controlled?

A
  • The Flaps are electrically requested and hydraulically powered by the Left, AUX, or PTU pressure.
  • Flap control in the Flap/Stab computer is DC

Q

What happens with a HOPS?

A

The Aileron HOPS shuts off both actuators whereas Elevators and Rudder only shuts down the affected actuator.

CLARIFICATION: Elevator has two actuators (HOPS will shut down 1 of 2). Rudder has only 1 actuator (HOPS will shut down 1 of 1).

A

Yoke Trim Switches

18
Q

Selecting the EMER STAB switch ON (ARM):

A
  • Illuminates ARM in switch

  • STABILIZER positioned by using YOKE electric pitch trim wheels
19
Q

Selecting the EMER STAB switch OFF:

A
  • Switch is dark
  • EMER STAB mode disabled
  • STABILIZER now moves corresponding to flap position.
20
Q

Selecting STALL BARR switch to OFF:

A
  • OFF illumination in switch
  • STALL BARRIER CAS displays
  • Stick Pusher is Disabled
  • Stall Warning stick shaker continues to function
21
Q

Selecting STALL BARR switch ON:

A
  • Must be selected ON for all flight operations unless a malfunction OR
  • Procedural reasons require switch to be selected OFF
22
Q

Selecting PITCH TRIM ENG / DISENG switch to ENG:

A
  • DISENG (AMBER) is extinguished
  • Pitch Trim is engaged
  • YOKE pitch trim switch is active for elevator trim
23
Q

Selecting PITCH TRIM ENG/DISENG switch to DISENG

A
  • DISENG (AMBER) is illuminated
  • YOKE pitch trim is disengaged
  • MANUAL TRIM WHEEL must be used for elevator trim
24
Q

Selecting YAW DAMP ENG / DISENG switch to ENG

A
  • DISENG (AMBER) is extinguished

- YAW dampers are disengaged

26
Q

Selecting the GPWS/GND SPLR switch to ON:

A
  • ON (AMBER) legend is illuminated
  • Automatic ground spoiler deployment will occur with flaps < 22 degrees and both struts have Wheel Speed Spin up
  • GPWS voice alarm “TOO LOW FLAPS” is inhibited
27
Q

Selecting the GPWS/GND SPLR switch to OFF:

A
  • ON (AMBER) legend is extinguished
  • Automatic ground spoiler deployment will occur with flaps < 22 degrees only when Weight On Wheels has occurred
  • GPWS voice alarm “TOO LOW FLAPS” is NOT inhibited
28
Q

Selecting the GND SPLR switch to OFF:

A
  • OFF (AMBER) is illuminated
  • Ground Spoiler System is not armed to operate
  • Gear Down the blue “Ground Spoiler Unarm” CAS message will appear
29
Q

A
  • Select the GND SPLR switch to ARMED (BLUE) is illuminated
  • Both throttles at idle
  • Wheel spin up OR WOW ground on each main gear strut
30
Q

NO GND SPLRS red switch lights on center windscreen post illuminate if:
