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
- When conducting the ground spoiler preflight test, what are the proper
indications when the “TEST” button is pressed?
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
- During the cockpit preflight inspection, how can the flaps be set to 10 degrees
in preparation for the exterior preflight inspection?
By activating the auxiliary hydraulic pump
- What hydraulic sources are available to operate the flaps using the emergency
flap control?
Combined, utility and auxiliary
- If the FLAP CONT circuit breaker has tripped, what is the affect on the flap
system?
Normal flap operation is not available
Emergency flap operation may be available
- If the MANUAL FLAP CONT circuit breaker has tripped, what is the affect on
the flap system?
Both normal and emergency flap operation will be inoperative
- With a loss of essential DC bus power, what is the effect on the flap system?
Both normal and emergency flap operation will be inoperative
- How would a flap asymmetry condition affect flap operation?
Both normal and emergency flap operation will be inoperative
- What is the limitation regarding the use of the autopilot with emergency flap
operation?
Do not engage the autopilot when using the emergency flaps unless flap
deflection is 10º or greater
- What is the first required action with an undesired flap movement?
Select the emergency flap switch to “EMERGENCY”
- When is the amber “STAB-FLAP FAIL” CAS message displayed?
When the flaps are fully up but the stabilizer is not fully up
- What are the resulting indications when emergency flaps are used?
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
- What flap setting would you use with a combined fluid loss (assuming you
move them)?
Flaps 20, aux hydraulic pump operation is extremely slow (in case of Go-around)
- What is required to energize automatic ground spoilers upon landing if the
flaps are less than 22°?
Power levers at idle and weight on wheels, or
Power levers at idle with the GPWS ground spoiler flap override switch selected
ON and wheel speed spin-up
- What is normally indicated by a red “X” on the AOA indicators?
Emergency flap operation is in use and AOA indications may not be reliable
- What is the limitation regarding the use of the autopilot with emergency flap
operation?
Do not engage the autopilot when using the emergency flaps unless flap
deflection is 10º or greater
