How does CG change as fuel burns
With full Center tank the CG will move rearwards.
Once Center tanks are empty initially moves forward and then moves rearward again until an inner tank has approximately 5000lbs and the moves rapidly forward before moving rearward again

Explain side stick
- Used to exercise manual control of pitch and roll
- Not coupled mechanically
- Send seperate sets of signals to the flight control computers

- Radio communication trigger
Explain Fly by Wire
- Replaces mechanical linkage as found on conventional aircraft
- Pilot inputs do not directly move the flight control surfaces

How does Auto brake work
- Establish and maintains a selected deceleration rate
- Reduces the distance during an RTO
- Three setting, LO, MED and MAX
- MAX can not be armed in flight
- Activates at spoiler extension for LO and MED
- MAX activates at spoiler extension and speed above 40 knots
- Therefore RTO below 72 knots no AUTOBRAKE because spoilers don’t deploy
- Deactivated via press button, arming condition lost, after a touch and go, or by pressing on brake pedal
How does Alternate braking work
- As per normal braking, powered by Yellow Hydraulics
and backed up by a brake accumulator. - The Alternate Braking Control Unit (ABCU) electrically controls the alternate braking.

Bank Angle protection
- Above 33* if side stick released, aircraft rolls back to 33*.
- Can not exceed 67* in normal law
- Past 45* need nose up input to maintain level flight
- If high speed or attitude protection is activated, bank limit is 45* and if high speed is activated and stick released wings will roll level

- Alpha Floor activates TOGA regardless of thrust lever position
Flight control protections always available?
No, some are lost when the aircraft is not in Normal Law:
1. Bank angle
2. Pitch attitude
3. Speed protections change to Low speed and high speed stability which the pilot can override
What is Alpha Floor
- A protection that commands TOGA thrust regardless of thrust lever position
- Lies betweem V alpah prot and V alpha max on speed tape
Is Alpha Floor always available
No, lost when aircraft is no longer in Normal Law which means the aircraft can be stalled
What is stall recover procedure
- Nose down pitch control - apply
- Bank - wings level
- Thrust (when out of stall) - increase smoothly as needed
- Speed brakes - check retracted
- Flight Path - recover smoothly
- If clean below 20’000 feet - Flaps 1 select
When is thrust added during stall procedure
Once aircraft is out of the stall. No more “STALL STALL STALL” or if buffet has stopped, positive indication on the speed tape
Is there an indications of angel of attack
No Angle of Attack indicator per say. However the top of the red strip on the bottom of the air speed tape indicates V alpha max, which is speed for the maximum angle of attack achievable in Normal Law

What does the RAT do
- Powers the Blue Hydraulic System
- This then powers the Emergency Generator
- EG powers the AC ESS BUS and DC ESS BUS
Why is there a 10 second delay before firing first agent after pushing the FW pb
10 second delay allows N1 to decrease, reducing nacelle ventilation, and thereby increasing the effect of the agent. [Automatic countdown on the ECAM].

How is center tank fuel used
- The Fuel Level Sensing Control Unit (FLSCU) opens the center tank transfer valves when the engines have used 1100 lbs of inner tank fuel
- When the transfer valve is open, fuel from the inner tank pumps flow through the jet pump and creates a suction which moves fuel from the center tank to the related inner tank
