Flashcards in Final Exam Deck (57)
True or False: The pack regulators provide commands to the zone regulator. (A320 - air conditioning)
True or False: the pack regulators receive commands from the zone regulator and control and monitor their respective packs.(A320 - air conditioning)
Close the pack flow control valve for PACK 1 using the correct pb on the overhead AIR COND panel. (A320 - air conditioning)
Select the PACK 1 pb so that OFF is illuminated in white
Are the cargo bins heated and pressurized? Or which ones (A320)
Majority of bins are pressurized on aircraft, but don’t always have temperature control (heat)
If both ELACs fail or are shut off, the flight control system degrades from normal law to ____ law
What systems provide a backup elevator and THS pitch control if both ELACs should fail?
SECs 1 and 2
- SECs do not provide backup Yaw control
What system controls rudder movement for automatic turn coordination, yaw dampening, rudder limiting, and rudder trim?
What are the 3 independent hydraulic systems on the A320?
If both sidesticks are moved in the same direction at the same time:
The inputs from the two sidesticks are summed (but can never exceed the input realized if there is full deflection on only one sidestick)
Slat alpha/speed lock:
PREVENTS you from RETRACTING the slats, if extended if the angle of attack becomes excessive or airspeed is too low
What are the 3 "Laws" and what is their purpose?
- Each programmed with "protections" that, if exceeded, will automatically override pilot controls
Which "Law" will become active after multiple failures of certain systems?
Which "Law" will become active as a result of a more SIGNIFICANT system failure? (ex landing gear)
Will the failure of a SINGLE flight computer cause a downgrade from Normal Law to alternate or direct?
Pitch protections provided in normal law include:
1. Maneuver Protection
2. Pitch Attitude protection
3. High speed and alpha protection
Can the A320 stall when in Normal Law?
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
There is an overflow return coming from the Surge Tank. Where are the surge tanks located?
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
- During normal operations, center tank fuel is consumed first whenever the slats are retracted
With fuel in the right inner wing cell at approx 1650 lbs/750kg, which is true?
The transfer valve in both wings will open
True or False: There are no indications on the flight deck regarding transfer valve position.
True or False: When the transfer valves are in transit, the indications on the FUEL page change to AMBER
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 engine #2 driven pump, the PTU, OR an electric pump
The Blue hydraulic system can be pressurized by:
An electric pump or a RAT driven pump
