What is the expected HYD pressure when powered by the RAT? |
2500 PSI |
|
|
When will the PTU turn on automatically |
When differential HYD pressure between green and yellow system is greater than 500 PSI |
|
|
How can you close the HYD Fire shut off valve? |
By pushing the corresponding ENG FIRE pb |
|
|
Where does the air that pressurize the HYD reservoirs come from? |
HP bleed from ENG 1, cross bleed duct if pressure is low. (What if no bleed at all?) |
|
|
PUMP fault light comes on for |
Reservoir low level Reservoir overheat Reservoir low air pressure Pump pressure is low, for all these, once turn off, fault light goes out.
Pump Overheat, fault light stays on for the duration of the overheat even if turned off |
|
|
The RAT will deploy automatically if |
Both AC BUS 1 and AC BUS 2 is lost |
|
|
The PTU is inhibited during |
First engine start and tested after second engine start. PTU is also inhibited for 40s after end of cargo door operation. |
|
|
On the ECAM HYD page, the low level ranges represents how much volume? |
Green / Blue / Yellow 3.5L / 2.4L / 3.5L
Associated with RSVR LO LVL ECAM caution |
|
|
On the ECAM HYD page, what volume does the range of normal filling represent? |
Green / Blue / Yellow 2.6L / 1.6L / 2.6L |
|
|
On the ECAM HYD page, what is the volume of total fluid represented by the top of the normal fill range? |
Green / Blue / Yellow 14.5L / 6.5L / 12.5L |
|
|
On the ECAM HYD page, amber triangle with the RAT represents |
Pressure for stowing the RAT has been applied, or RAT Pump is not avbl.
Associated with ECAM HYD RAT FAULT |
|
|
In terms of ECAM caution, at what pressure will SYS LO PR and PUMP LO PR comes on? |
ENG pumps: 1750 PSI (reset @ 2250 PSI) ELEC pumps: 1450 PSI (reset @ 1750 PSI)
SYS LO PRESS: 1450 PSI |
|
|
When will RAT OUT memo be shown in AMBER? |
RAT is not fully stowed and during flight phase 1 and 2 (ELEC PWR to 1st ENG T/O PWR) |
|
|
What does ECAM HYD PTU FAULT mean? |
Differential pressure is above 650 PSI On ground: PTU not running Inflight: PTU still at AUTO when G&Y LO LVL or Y LO PR |
|
|
If HYD G/Y LO LVL, OVHT, LO AIR PR, the PTU will overheat after how long if not switched off according to ECAM? |
2 minutes |
|
|
According to SOP, a PUT fault is triggered if the second engine is started within 40s follow the end of the cargo doors operation, how to you fix it? |
Reset the warning by switching the yellow ELEC pump ON, then OFF
PUT is inhibited for 40s after end of cargo door operation, but also tested during 2nd engine start, the 2 actions perhaps creates a conflict hence causing the fault. |
|
|
What is the threshold for HYD RSVR LO AIR PR caution? |
321: Air pressure <= 22 PSI, reset @ 25PSI 320: Air pr <= 22 PSI, reset @ 25PSI In addition B RSVR <= 30PSI will also also trigger ECAM on ground after landing |
|
|
At what temperature will HYD RSVR OVHT comes on? |
93C, reset @ 88C |
