- Normal
- Alternate
- Direct
- Each programmed with “protections” that, if exceeded, will automatically override pilot controls
Which “Law” will become active after multiple failures of certain systems?
Alternate Law
Which “Law” will become active as a result of a more SIGNIFICANT system failure? (ex landing gear)
Direct Law
Will the failure of a SINGLE flight computer cause a downgrade from Normal Law to alternate or direct?
No
Pitch protections provided in normal law include:
- Maneuver Protection
- Pitch Attitude protection
- High speed and alpha protection
Can the A320 stall when in Normal Law?
Yes
What does Alpha Protection do for the A320?
Will move the flight control surfaces to prevent the AOA (alpha) form ever reaching or maintaining a stall
The ___ are the primary flight control computers
ELACs

In the outer section of each wing
The Fuel Quantity Indication (FQI) system measure what 2 things?
Fuel quantity and fuel TEMPERATURE
On the FUEL page, the temperature exceeds a preset limit, the corresponding indications will first flash GREEN. If high or low temperatures are further exceeded, the indications will turn AMBER.
Fuel temperature indications change to amber when a high or low limit is exceeded
What does an AMBER fuel temperature indicate?
That the temperature has risen above or fallen below a preset temperature limit
Regarding fuel usage with center tank fuel:
- Provided fuel is in the center tank, the center tank pumps feed the engines when slats are retracted

The transfer valve in both wings will open
True or False: There are no indications on the flight deck regarding transfer valve position.
False
True or False: When the transfer valves are in transit, the indications on the FUEL page change to AMBER
True
The Green hydraulic system can be pressurized by:
The engine #1 driven pump or the PTU (not an electric pump)
The Yellow hydraulic system can be pressurized by:

The Blue hydraulic system can be pressurized by:
An electric pump or a RAT driven pump
What is PSI is considered “normal” for the hydraulic systems?
3000PSI

True or False: the 2 Landing Gear Control Interface Units (LGCIUs) swap roles as controlling and back up of gear extension and retraction each time the landing gear is raised
True!
The primary method for monitoring gear position, the Landing Gear Indicator Panel, receives info from:
LGCIU 1
The max speed for gear extension is ___ knots and for gear retraction is ___ knots
250 ext
220 ret

- Continuously when airborne
- On ground for 5 min period following a/c power
