Flight Controls

Question 1

What might cause a red “ACFT CONFIG” CAS message to illuminate during takeoff? (2)

Answer 1

• Flaps not at 10 or 20 degrees

- Speedbrake handle not stowed

Question 2

If an engine is inadvertently started with the gust lock engaged, what is the appropriate procedure?

Answer 2

Shut down the engine and bleed the hydraulic pressures to zero before disengagement

Question 3

How is the external (single) rudder load limiter checked?

Answer 3

During engine starts, with the right engine operating and prior to starting the left
engine, the amber “SNGL RUDDER LIMIT” CAS message should be displayed
on the EICAS and the engine start page

Question 4

If an amber “SNGL RUDDER LIMIT” CAS message illuminates in flight, what is the corrective action?

Answer 4

Avoid abnormal rudder deflection

Question 5

How is the rudder torque limiter checked prior to flight?

Answer 5

Illumination of the blue “RUDDER LIMIT” CAS message with full rudder deflection

Question 6

Is the yaw damper required to be operative or engaged for autopilot operation?

Answer 6

The yaw damper must be operative and it will automatically engage when the autopilot is selected ON

Question 7

What is the function of the GPWS ground spoiler flap override switch? (2)

Answer 7

• Provides ground spoiler deployment upon wheel speed spin-up in the event of a partial flap landing
• Inhibits the GPWS “TOO LOW, FLAPS” callout

Question 8

Is ground spoiler deployment available with a loss of combined system fluid?

Answer 8

Yes, the auxiliary hydraulic pump provides the “pop-up” signal and the flight hydraulic system provides hydraulic pressure to move the ground spoiler panels

Question 9

What is the immediate action required if the red “GND SPOILER” CAS message illuminates in flight?

Answer 9

Immediately position the ground spoiler arming switch to OFF

Question 10

When conducting the ground spoiler preflight test, what are the proper indications when the “TEST” button is pressed? (4)

Answer 10

• The ground spoilers should remain stowed
• A red “NO GND SPLR” light capsule illuminates on the glareshield
• A red “GND SPOILER” CAS message illuminates
• Both master warning light capsules illuminate

Question 11

During the cockpit preflight inspection, how can the flaps be set to 10 degrees in preparation for the exterior preflight inspection?

Answer 11

By activating the auxiliary hydraulic pump

Question 12

What hydraulic sources are available to operate the flaps using the emergency flap control?

Answer 12

• Combined
• Utility
• Auxiliary

Question 13

If the FLAP CONT circuit breaker has tripped, what is the affect on the flap system?

Answer 13

• Normal flap operation is not available

- Emergency flap operation may be available

Question 14

If the MANUAL FLAP CONT circuit breaker has tripped, what is the affect on the flap system?

Answer 14

Both normal and emergency flap operation will be inoperative

Question 15

With a loss of essential DC bus power, what is the effect on the flap system?

Answer 15

Both normal and emergency flap operation will be inoperative

Question 16

How would a flap asymmetry condition affect flap operation?

Answer 16

Both normal and emergency flap operation will be inoperative

Question 17

What is the limitation regarding the use of the autopilot with emergency flap operation?

Answer 17

Do not engage the autopilot when using the emergency flaps unless flap deflection is 10º or greater

Question 18

What is the first required action with an undesired flap movement?

Answer 18

Select the emergency flap switch to “EMERGENCY”

Question 19

When is the amber “STAB-FLAP FAIL” CAS message displayed?

Answer 19

When the flaps are fully up but the stabilizer is not fully up

Question 20

What are the resulting indications when emergency flaps are used? (5)

Answer 20

• A red “X” on both AOA indicators
• No valid auto-speed target (999 in the speed window)
• No valid perf computer speeds on the FLT REF page
• Autothrottles will disconnect
• A “FLAP INPUT INVALID” scratchpad message

Question 21

What flap setting would you use with a combined fluid loss (assuming you move them)?

Answer 21

Flaps 20, aux hydraulic pump operation is extremely slow (in case of go-around)

Question 22

What is required to energize automatic ground spoilers upon landing if the flaps are less than 22°?

Answer 22

1. Ground Spoiler switch selected to ARMED, power on the Essential DC bus, and power levers at idle and weight on wheels

OR

2. Ground Spoiler switch selected to ARMED, power on the Essential DC bus, and power levers at idle with the GPWS/GND SPLR FLAP ORIDE switch selected ON and wheel speed spin-up activated

Question 23

What is normally indicated by a red “X” on the AOA indicators?

Answer 23

Emergency flap operation is in use and AOA indications may not be reliable

Question 24

What is the limitation regarding the use of the autopilot with emergency flap operation?

Answer 24

Do not engage the autopilot when using the emergency flaps unless flap deflection is 10º or greater

Question 25

What conditions must be meet for automatic deployment of Ground Spoilers?

Answer 25

• Combined, Utility, or AUX Hydraulic pressure for servo control
• Combined or Flight Hydraulic Pressure to extend spoilers
• ESS DC Bus and Left Main DC Bus powered
• Ground Spoiler Switch – ARMED
• Both Power Levers – IDLE
• Nutcrackers - Ground Mode or wheel spin up when:
  · Flaps greater than 22 degrees
  · Flaps position less than 22 degrees and Ground Spoiler Flap Override Switch selected ON

Question 27

When is use of the Speed Brakes prohibited?

Answer 27

Use of Speed Brakes are not approved for use with Flaps at 39 degrees (DOWN) or with Landing Gear extended in flight
