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.
