Flight Controls Flashcards
What conditions must be meet for automatic deployment of Ground Spoilers?
Combined, Utility or AUX HYD Pressure for servo control Combined or Flight HYD Pressure to extend the 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
-The Ground Spoiler Flap Override Switch selected ON
When is use of the Speed Brakes prohibited?
Use of Speed Brakes are not approved for use with Flaps at 39 degrees (DOWN) or with Landing Gear extended in flight
What are the maximum speeds for Flap extension:
10 degrees?
Flaps 10 - 250 KCAS
What are the maximum speeds for Flap extension:
20 degrees?
Flaps 20 - 220 KCAS
What are the maximum speeds for Flap extension:
39 degrees?
Flaps 39 - 180 KCAS (SP)
What is the maximum operating altitude for extending landing Flaps (39 degrees)?
20,000 FT MSL
- What might cause a red “ACFT CONFIG” CAS message to illuminate during
takeoff?
Flaps not at 10 or 20 degrees
Speedbrake handle not stowed
- If an engine is inadvertently started with the gust lock engaged, what is the
appropriate procedure?
Shut down the engine and bleed the hydraulic pressures to zero before
Disengagement
- How is the external (single) rudder load limiter checked?
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
- If an amber “SNGL RUDDER LIMIT” CAS message illuminates in flight, what is
the corrective action?
Avoid abnormal rudder deflection
- How is the rudder torque limiter checked prior to flight?
Illumination of the blue “RUDDER LIMIT” CAS message with full rudder deflection
- Is the yaw damper required to be operative or engaged for autopilot
operation?
The yaw damper must be operative and it will automatically engage when the
autopilot is selected ON
- What is the function of the GPWS ground spoiler flap override switch?
Provides ground spoiler deployment upon wheel speed spin-up in the event of a
partial flap landing
Inhibits the GPWS “TOO LOW, FLAPS” callout
- Is ground spoiler deployment available with a loss of combined system fluid?
Yes, the auxiliary hydraulic pump provides the “pop-up” signal and the flight
hydraulic system provides hydraulic pressure to move the ground spoiler panels
- What is the immediate action required if the red “GND SPOILER” CAS
message illuminates in flight?
Immediately position the ground spoiler arming switch to OFF
