Flight Controls Flashcards
How many A/B panels are there:
4, 2 on each side
Which controls are Locked with the Control Lock:
Elevator and Rudder (also blocks the TL so they can’t be advanced)
How are the ailerons gust protected:
Resistance from hydraulics
How many motors does it take to operate Slats and Flaps:
How many actuators:
2 electrical motors - 1 for Slats and 1 for Flaps
Drives flexible cables to screw jacks
3 for each SLAT and 1 for the INB FLAP, 2 for the OB
What’s the difference between the FLIGHT A/B’s and the GROUND A/B’s:
Ground A/B’s uses a separate switch, actuate faster and can be ARMED for automatic deployment at touchdown
What will trigger the Take Off Warning horn:
Trim not in green band
A/B’s not retracted
Flaps not set for takeoff (0, 12 or 20)
Slats not extended (ByPass button not pressed)
When is the AOA Indexer armed:
When Slats are extended
If auto extension of the SLAT’s occur how are they retracted:
By matching the Flap/Slat handle to the extended slat position regains control
Where is the Flap Slat Electronic Control Unit (FSECU) located:
Can it be reset:
In the lavatory
Maintenance ONLY
How many trim motors are you using with NORMAL trim:
In OVRRD:
EMER trim:
Can you dispatch with either trim motor inoperative:
What should the trim be set to for an exterior preflight:
2 - 1 and 3 1 - Only number 2 All 3? NO Zero (0 degrees)
Will the YD turn OFF when you press the AP disconnect button when Landing or with the GA button on a MA:
ONLY if Flaps are at 40 degrees, otherwise you must select it OFF on the FCP
Typically what is the position of the Horizontal Stabilizer Trim at cruise:
minus 1 or 2 degrees
Has there ever been a JAMMED STAB on the G100:
YES - One on takeoff and One at cruise
Has there ever been an AP / YD failure of the G100:
YES - 3, two from AHRS failures and One from an internal failure
Has the main cabin door ever come OPEN in flight on the G100:
YES - 3 times, one door left the aircraft entirely
How trim motor(s) are used during NORMAL and AP trimming:
Number 1 and 3 below 250 KIAS and number 1 above 250
What could happen if you lost the HEAT BLANKET on the TRIM ACTUATOR:
JAMMED STAB
When does the AUTO SLAT system operate:
Assuming the AUTO SLAT OVRD pushbutton is not pushed ON: In flight, below 250 KIAS (M .55) and AOA is at .8
When will the Ground A/B’s deploy automatically:
When will the Ground A/B’s retract automatically:
A/B switch in ON (armed) position and either main gear WOW switch senses ground mode
They WON’T, must be manually retracted
How many ways can you disengage the AP:
Either AP DISC or GA button
Either horizontal trim
OVRD TRIM button
GANG BAR
When selected, when will the Flaps move out of the UP position:
If SLAT OVRD is not selected, when the SLATS are fully down
What is the Landing Performance penalty when landing SLATS and FLAPS UP:
No FLAPS:
No SLATS / FLAPS 20:
50%
30%
30%
What is the Landing Performance penalty when landing with a JAMMED STAB:
10%
How are the A/B’s held down:
Down locks
