Flap Auto Retraction System (ARS)
In CONF 1+F the FLAPS (not slats) will automatically retract to 0 at 210 kts
FLAPS / SLATS
Q: What happens to the ailerons when the flaps are extended?
Ref: (FOM VOL. III-DSC-20-10-20)
The ailerons droop 5˚
FLAPS / SLATS
Q: When the FLAP legend appears in cyan on the upper ECAM display what is indicated?
Ref: (FOM VOL. III-DSC-27-30-20)
Flaps/slats in transit
FLAPS / SLATS
Q: With only Green hydraulic system pressure available, will both the flaps and slats operate?
Ref: (FOM VOL. III-DSC-27-30-10)
Yes, at ½ speed
How may Slat/Flap Control Computers (SFCC) are installed?
2
If one spoiler becomes faulty or inhibited, what happens to opposite spoiler?
The faulty one is retracted and the opposite side is retracted to prevent asymmetry.
Let’s assume the FO presses his take over pb and releases it after more than 40 secs…
The Capt’s sidestick is de-activated unless he presses his take over pb.
SEC Duties
(PAR SS)
- Pitch
- Abnormal attitudes
- Roll
- Speed brakes
- Spoilers
SPEED BRAKES / SPOILERS
Q: At touchdown with reverse selected and only one landing gear strut compressed, will the ground spoilers extend?
Ref: (FOM VOL. III-DSC- 27-10-20)
Partially – Full extension is limited until both main gear struts are compressed
SPEED BRAKES / SPOILERS
Q: In flight, what happens if a spoiler fault is detected or electrical power is lost?
Ref: (FOM VOL. III-DSC-27-10-20)
The spoiler automatically retracts
SPEED BRAKES / SPOILERS
Q: Is there any landing configuration when speed brake extension is inhibited?
Ref: (FOM VOL. III-DSC-27-10-20)
Flaps FULL
SPEED BRAKES / SPOILERS
Q: What is the difference between the A319 - A321 and A320 regarding speed brake usage with the AP on?
Ref: (FOM VOL. III-DSC-27-10-20)
With the A319 and 321 you get full spoiler deflection and with the A320 you only get partial spoiler deflection
SPEED BRAKES / SPOILERS
Q: When do the Ground Spoilers automatically extend?
Ref: (FOM VOL. III-DSC-27-10-20)
- Partial – When reverse thrust is selected on at least one engine with the other at idle and one main landing gear strut is compressed
- Full – At touchdown of both main gear , or in case of RTO with airspeed above 72 knots, when BOTH thrust levers at IDLE (if ground spoilers armed) or when reverse thrust is selected on at least one engine with the other thrust lever at IDLE (if the ground spoilers are not armed)
SPEED BRAKES / SPOILERS
Q: When is speedbrake extension inhibited (SAFET)?
Ref: (FOM VOL. III-DSC-27-10-20)
- SEC 1 and 3 have failed
- AOA protection is active
- Flaps FULL
- Elevator (L or R) fault (only spoilers 3 and 4 are inhibited)
- Thrust levers above the MCT position
SPEED BRAKES / SPOILERS
Q: When will the ground spoilers automatically retract?
Ref: (FOM VOL. III-DSC-27-10-20)
When at least one thrust lever is advanced above IDLE
Speedbrakes Inhibited
(SEAFAT)
- SEC 1 AND 3 fault
- Elevator L or R fault
- Alpha Protection active
- Flaps Full
- Alpha Floor active
- Thrust Levers > MCT
The steering hand wheels can steer the nose wheel up to how much in each direction?
75º
TRIMMABLE HORIZONTAL STABILIZER
Q: How is the THS normally operated in flight?
Ref: (FOM VOL. III-DSC-27-10-20)
The flight control computers control trim functions automatically
TRIMMABLE HORIZONTAL STABILIZER
Q: Can you move the PITCH trim wheel if all systems are working normally?
Ref: (FOM VOL. III-DSC-27-10-20)
Manual inputs have priority over computer inputs. The autopilot will disconnect
TRIMMABLE HORIZONTAL STABILIZER
Q: If a complete flight control computer failure occurs can the THS be positioned?
Ref: (FOM VOL. III-DSC-27-10-20)
Yes, mechanical trimming is possible by manually positioning the Pitch Trim Wheel
TRIMMABLE HORIZONTAL STABILIZER
Q: If NO hydraulic power is available can the THS be positioned?
Ref: (FOM VOL. III-DSC-27-10-10)
No - the THS requires hydraulic power from the Green or Yellow systems
TRIMMABLE HORIZONTAL STABILIZER
Q: What happens to the THS when the aircraft enters into Ground Mode?
Ref: (FOM VOL. III-DSC-27-20-10-20)
The trim automatically resets to zero (inside the green band)
What are the two configurations produced by position 1 on the flaps lever?
- 1+F (Slats and Flaps) for takeoff
- 1 (Slats Only) in flight
What does a
WING TIP BRK ON
message on the E/WD indicate?
A hydraulic device locks the flaps in their present position.
What system prevents flap or slat asymmetry?
Wing Tip Brakes (WTB)
What would happen if one of the two SFCC’s failed?
Slats and flaps operate at half speed
When using the rudder pedals for steering, when does the steering angle begin to reduce?
Starts reduction at 40 knots and progressively reduces to zero degrees at 130 knots
WINGTIP BRAKES
(ROAM)
- Runaway of surface
- Over speed of mechanism
- Asymmetry
- Movement of surface un-commanded
