System Review Question Flashcards
(104 cards)
What is the maximum continuous engine starter operation time
5 minutes
What is the maximum EGT during engine start
700c
What is the keep out zone logic with regard to the engines fitted to the A330
In order to prevent fan stability, this logic avoids stabilised engine operation between the 1.16 to 1.28 EPR range, when on the ground
Which flight computers are part of the thrust reverser deployment actuation logic
PRIM 1 or PRIM 3
During a dry crank, what is the min time required to clear fuel vapours
30 seconds
What is the maximum speed in flight following an ENG REV UNLOCKED ECAM with associated buffeting
250kt
FADEC has two channel redundancy
One is active and on standbye
During the engine start sequence, the starting sequence indications appears
On the ENG SD page
The FADEC provides protection against ___ turbine over speed due to ____ shaft breakage between compressor and turbine. If it occurs, the engine is shut down by closing the ____ shut off valve. Indelent of the FADEC, the engine is fitted with the N1/N2 over speed protection unit
Low pressure
Low pressure
High pressure
The aircraft reverses engine thrust by using four pivoting blocker doors on each engine to deflect the fan airstream. The FADEC will automatically command the engine to idle and the reverser to stow if at least ____ door(s) is / are ____ by more than ____% and reverse thrust is not selected while the engine is running. The affected reverser will remain pressurised after the affected door is locked back.
One
Unstowed
5%
If PACK REG is displayed on the COND SD page
Both zone controller channels have failed, optimised temperature regulation is lost and packs will deliver a fixed outlet temperate of 20c
You have selected the zone template rotary selector on the overhead panel to the 12 o’clock position. Within which temp range can the cabin crew now control the cabin temp from the forward attendant panel?
21-27c
During your pre flight cockpit prep, when might you select pack flow to LO?
If less than 60% of economy class seats are occupied but not more than 200 total passengers
CAB PR EXCESS CAB ALT appears on the ECAM. You should?
Rely on the ECAM warning even if it is not confirmed on the CAB PRESS SD page
A CAB VERT SPD ECAM advisory has triggered, due to the cabin v/s exceeding 1800fpm in the climb or -1800 ft/min in the descent. The recommendation is to perform a CPC changeover. This is completed by
Selecting the CABIN PRESS MODE SEL pb to MAN. After 3 seconds set back to AUTO.
Once a you adjust cabin temp ln the overhead panel. How long should you wait for allow this to take affect?
20 mins
Due to failure of both CPCs, manual cabin vertical speed control is required. What are the target rates for climb and descent.
Climb 500fpm
Descent 300fpm
The fuel system cross feed value
Enables any pump to supply any engine and Leon’s automatically during electrical emergency configuration.
The trim tank transfer system controls the CG, automatic CG control would normally …
Begin during climb to FL255 or above
End at descent to FL245
End when there is less than 35 mins to dest or less than 75 mins in the event of a trim tank forward transfer pump failure
If req in an emergency situation, fuel jettison can be achieved at an output rate of
1000kg per minute
The upper ECAM display shows the fuel on board. If an amber half box appears around the FOB figure
The indicated fuel quantity is not fully usable
In the event of wing tank gravity refuelling. With both side couplings used and normal pressure, the time to refuel all tanks is
33 mins
Transfer from the centre to inner tanks can be manually selected with the ____ pb. When selected MAN, the inner tank inlet valves are opened and the ___ pumps run.
CTR TK XFR
CTR TK
Each FCMC calculates the fuel quantity by using the:
Volume, density, horizontal stab angle, aircraft attitude and electrical characteristics from the compensators
