Flight Controls Flashcards
The purpose of aileron flutter damper is
Prevent control surface flutter when hydraulic power is lost to the PCUs in flight.
Act as gust lock on ground. Only on Ailerons.
What aids the crew in directional control during a jammed rudder condition
Rudder system anti-jam breakout mechanism
What hydraulic system powers the inboard ground spoilers
3 system
What hydraulic system powers the left aileron
System 1 and 3
What are takeoff flap settings
8° and 20°
The elevators, rudder and ailerons are
Manually controlled and hydraulically actuated
What is the purpose of the aileron bungee breakout switch
Provides automatic MFS control transfer to unpoppable circuit during aileron PCU runaway
What is the horizontal stabilizer trim rate went activated by a pilot
0.5° per second Please check this answer
The Horizontal Stabilizer trim limits are:
+2° to -13°
What is the control priority for the Stabilizer Trim?
Pilot, Copilot, Autopilot, Flap compensation trim, Mach Trim?
A SPOILERONS ROLL caution message, accompanied by amber ROLL SEL lights on the glareshield indicates
Roll disconnect handle has been pulled but spoileron priority has not been established.
What are the selectable Flap positions?
0 – 1 – 8 – 20 – 30 – 45
What message appears on EICAS if one channel of flap electronic control unit (FECU) fails?
Flaps Halfspeed
How many Fluttered Dampeners are installed on the left elevator?
None
During landing or rejected takeoff, how does multifunction spoilers deploy logic differ from the ground spoilers deploy logic?
Multifunction spoilers deployment requires R and L main landing gear WOW
Primary flight controls include:
rudder, ailerons, elevators
In the event of total AC electrical power failure, the flight controls will remain operational because ACMP 3B is powered by the ADG bus.
True
Each elevator is hydraulically powered by_____PCU’s.
3
A clacker will activate when the horizontal stabilizer is in motion for more than:
3 sec.
Slats/Flaps position indications are displayed on the EICAS primary page whenever one or more the following conditions exist:
Slats or flaps are greater than zero
landing gear is down
BTMS is red
Name the primary flight controls
Elevators, rudder, ailerons
Name is secondary flight controls
Horizontal stabilizer trim
Slats/flaps
Multi-function spoilers
Ground spoilers along with the associated aileron and rudder trim systems
What components are on hydraulic system one?
Rudder Elevator Left aileron Outboard Spoileron Outboard flight spoilers Outboard ground spoilers Left reverser
What components are on hydraulic system two?
Writer Elevator Right aileron Inboard spoiler on In board flight spoilers MLG aux act Right reverser
What components are on hydraulic system three?
Rudder Elevator Left and right aileron Inboard ground spoilers Landing gear Nose wheel steering
Explain when ground spoilers will deploy for ground lift dumping?
You must have: Thrust levers idle or reverse and 2 of these 3: -Radio altimeter <7 feet agl -Wheel spin up -Weight on wheels on EITHER wheel.
Explain when the Multi function spoilers will deploy for ground lift dumping?
#1) After the ground spoilers deploy and... -Thrust levers at idle or reverse - Both weight on wheels - Either : Wheel spin up OR Rad Alt less than 7 ft agl.
