Flight Controls Flashcards
In Alternate Law, what are you commanding when you move the side stick forward and aft?
Load Factor (neutral equals 1.0g), (same as Normal Law, but with reduced protections)
In Alternate Law, what are you commanding when you move the side stick left and right?
Direct side stick to roll control surface position relationship
In Normal Law, what happens if both pilots move their side sticks simultaneously?
If both pilots move their sticks simultaneously, the inputs are algebraically summed (Limited to the maximum defection of a single side stick)
What is required to lockout a faulty side stick?
Pressing and holding the priority takeover pb for 40 seconds locks out the other side stick
With a side stick locked out, is an autopilot available?
Yes
The ELACs control which functions?
Elevator Aileron Computer (functions include listed controls and horizontal stabilizer control)
- Normal Elevator
- Aileron
- Horizontal Stabilizer
The SECs control which functions?
Spoiler Elevator Computer (functions include listed controls and horizontal stabilizer control)
- Spoiler
- Standby Elevator
- Horizontal Stabilizer
The FACs control which functions?
Flight Augmentation Computer:
- Electrical Rudder Control
- Flight Envelope functions
- Low level energy warning
- Windshear detection
What does a white OFF light indicate when associated with a ELAC, SEC, or FAC?
Computer is deactivated
During manual flight, you notice on the ground the glare shield these two lights flashing. (green CAPT and green F/O) What does this indicate?
Dual Input - both side sticks are being used simultaneously and aural “DUAL INPUT” warning
If both pilots are pulling back slightly on their sticks, what is the response of the aircraft?
A more pronounced pitch up since the inputs are algebraically summed
Both pilots should not make control inputs at the same time. If a pilot needs to takeover the controls what should be done to prevent dual input?
Press and hold the Auto-Pilot Disconnect/Takeover button
If a pilot needs to takeover the controls what should be done to prevent dual input?
Press and hold the Auto-Pilot Disconnect/Takeover button
During manual flight, you see the indications below and hear the aural alert “PRIORITY RIGHT.” What does this mean?
(Red right arrow on CAPT glare shied and green F/O on F/O glare shield)
To lock out the CA’s side stick, how long must the F/O hold the takeover pb?
The FO is holding the takeover pushbutton and inputs are being commanded on the CA’s side stick - would be accompanied by the aural “PRIORITY RIGHT”
40 Seconds
Can the AP be engaged after a side stick is locked out?
Yes
With a side stick locked out, can the associated AP be engaged?
Yes, the takeover-side AP is available
What do these green marks indicate?
Bank angle limit in normal law
Can you exceed the g-load (load factor) protections in Normal Law?
No
Can the aircraft stall in Alternate Law?
Yes
Is Load Factor protection available in Alternate Law?
Yes
Is Auto Trimming available in Alternate Law?
Yes
In Alternate Law after lowering the landing gear, the PFD displays this message… What has occurred?
Reversion to Direct Law
If the speed brake handle is armed, what is required to activate the Ground Spoilers during a rejected takeoff?
Speed > 72kts, both Thrust Levers at or near Idle, or if handle is NOT armed: speed > 72kts, with at least one thrust lever in reverse and other thrust lever at or near idle
With the AP ON, what maximum speed brake is available…
- On the A320
- On the A321
- On the A320
- Half
- On the A321
- Full
List at least two conditions in which the Speed Brakes will automatically retract?
- In flight, Flaps FULL for A320 (Flaps 3 and FULL for A321)
- Alpha Prot
- TOGA Thrust selected
Speed Brakes are inhibited (and will auto-retract if extended) in relation to what Flap position…
- For the A320
- For the A321
- For the A320
- Full
- For the A321
- 3 or Full
In Normal Law what occurs as the aircraft slows to Alpha Protection?
- AOA Protection becomes active, and:
- A- autopilot disconnects
- S- speed brakes retract
- A- side stick behavior changes from load-factor demand to AOA proportional to side stick deflection
- P- pitch trim (nose up) inhibited
- What flight control law is represented by the indications shown on the airspeed tape?
- If the speed brakes are extended, what will occur if airspeed decreases below the speed shown by the arrow (inside the yellow and black arc)?
- Normal Law
- Speed brakes auto retract at Alpha Prot
What protection occurs at a predetermined angle of attack between Alpha Prot and Alpha Max?
Alpha Floor protection engages. Autothrust provides TOGA thrust regardless of thrust lever position provided Autothrust is available/ operable. Although Alpha Floor can engage at any airspeed, it will certainly engage between A Prot and A Max
What does Alpha Max represent?
The speed corresponding to the maximum angle of attack that the aircraft can obtain in Normal Law
If the side stick is held full aft, will Alpha Max be exceeded?
No, Alpha Max cannot be exceeded even if the side stick is pulled and held fully back
If the side stick is held full aft, will the aircraft enter a stall?
No, Alpha Max cannot be exceeded even if the side stick is pulled and held back. (Barring extraordinary circumstances, such as extreme environmental conditions).
