Falcon 900b Flight Controls Flashcards
How are the ailerons and elevator controlled?
Mechanical linkage out to the control surfaces which control hydraulic servo actuators at the surfaces.
Which hydraulic system(s) is used to control the slats?
Either #1 OR #2 system (27-2)
Which hydraulic system is used to control the flaps?
2 hydraulic system
Which hydraulic system is used to control the airbrakes?
2 system
What happens to the elevators after shutdown?
They move slowly to the fully down position
What does the emergency aileron system do?
In the event the normal aileron system locks up, a servo actuator in the left wing (which controls the aileron) can be controlled by two red buttons in the trim quadrant on the pedestal.
If the left emergency servo actuator does not work the system will operate the right servo actuator.
What is the maximum deflection of the emergency aileron servo actuator?
7 degrees
Which hydraulic system controls the aileron Arthur Q unit?
system 2
Which hydraulic system controls the elevator Arthur Q unit?
system no. 1
If the arthur Q units fail what position do they fail to?
To the lower speed, “controls easy position”.
How is the aileron trim controlled?
It is electrically controlled but hydraulically actuated.
What type of motor drives the flaps?
hydraulic
What causes the T/O CONFIG and the aural “no takeoff” light to illuminate on the warning panel?
On the ground
- At least one power lever more that 84˚
- Flaps extended beyond 22˚
- Airbrakes not stowed
- Elevator trim not in the green
Can the standby pump be used to lower the flaps?
Yes, both the flaps and the standby pump are on #2 hydraulic system. 27-22
Three actuators power each outboard slat. One is an extend force slat only, the other two are double-acting? What is the extend force slat used for?
Emergency slats only. It will extend the slats but not retract them. The emergency slats are extended with the covered switch next the slat lever.
What will cause the slat button on the panel to blink?
When the emergency slats are extended. 27-25
What does the red arrow on the slats/flaps panel mean when it is lit?
That the slat position and the handle position do not agree.
What is the airspeed above which it is not authorized to operate with the AUTO SLATS light illuminated?
265 knots
From which system(s) do the auto slats get power?
Auto slats are the outboards only and they are dual powered by the A1 bus and the battery bus both of which control the hydraulic actuator.
The auto slats will deploy when the angle of attack vanes exceed _____˚, and are powered by the _____ and _____ hydraulic systems.
11˚ or 12˚, left and right
If the airplane AOA exceeds 23˚ what will happen to the slats?
The inboard slats will retract.
What other systems turn on when the auto slats deploy?
An audio warning and the igniters.
What are normal indications during slats test on the ground?
stall warning and igniter lights come on.
Which hydraulic system powers the emergency slats when the emergency slats switch is flipped on the pedestal?
Hydraulic system #2
Which airbrake panels extend with position one selected?
Center panels on each wing
Which airbrake panels extend with position two selected?
The inboard and outboard panels - ie. all six panels are extended.
What would cause the amber AIR BRAKE light to flash?
If either AOA vane exceeds 16.5 degrees the airbrakes will automatically retract and the airbrake light will flash
Can the flaps come down if the slats are not working?
No. The wing would not fly properly if the flaps came down without the slats. Slats always come down first.
Are the aileron and elevator trim systems hydraulic or electric?
They are both. An electric signal is sent to a hydraulic actuator that repositions the ailerons and elevator. (27-10)
How are the slats held in the retracted position?
With constant pressure from the #1 hydraulic system. (27-25)
From where do the outboard slats receive electrical power?
Two different solenoids drive the outboard slats out. One is the A1 Auto Slats breaker and the second is powered by the battery bus. (27-27)
What happens to the airbrakes at high angles of attack. (above 16.5˚)?
The airbrakes automatically retract.
