ATR72-600 Flight Controls| Exam Questions with Correct Answers Verified by Experts| Latest
Update
How is a critical AoA situation protected? 2x Stick shakers located on bottom of each Control
column.
1x Stick pusher located on Capt. Pitch channel
How is the Shaker/ Pusher controlled? MFC parameters exceeded.
- AoA
- Power Setting
- Flap Setting
- Flight Conditions.
What is lost if the STICK PUSHER guarded push button is depressed OFF? Shaker/ pusher are
switched off.
Stall warning aural alert is lost.
What is the Rudders' deflection amplitude? +/- 27Deg
How is Rudder deflection reduced at high speed to reduce damage? Travel Limitation Unit
(TLU)
How is the TLU controlled? Automatically by ADC 1/2 via CAC 1/2.
What is the RCU and what is it's function? Releasable Centering Unit (RCU)
- Enables Rudder position stabilisation
- Damps Dutch Roll tendency if YD fail.
, How is the Travel Limitation Unit controlled? Via the MFC.
What is the TLU's transition speeds? 185 knots accelerating
180 knots decelerating
How is the Rudder centering process completed? - Rudder trim levers deflected.
- RCU declutched.
- New position set.
How are the wing flaps connected? Mechanically by a torque shaft.
How many flap actuators are there? 4
What does a flaps green indication mean? Difference between flaps position and flaps
command is lower than 1 Deg.
What does a flaps amber indication mean? (3) - Flaps asymmetry
- Flaps jam
- Flaps command failure
What does a flaps red indication mean? Flaps unlock.
What does a repetitive appearance of the cyan flaps position after flaps have reached their
selected position in flight indicate? Leakage in Flaps Block Valve.
How does the aileron locking device work? An actuator located in each aileron pushes a
roller into a cam profile.
