|
When does the amber FAULT light illuminate on the primary and demand pumps? |
Low demand pump output pressure Excessive demand pump fluid temperature OR Demand pump is selected OFF |
|
|
|
What does 1.00 indicate on the hydraulic section of the status page? |
Normal fluid level |
|
|
|
OF code? |
Displayed when reservoir is over filled, it is inhibited in flight |
|
|
|
RF code? |
Reservoir requires refilling, inhibited in flight |
|
|
|
What does the engine fire switch do when pulled to the hydraulic system? |
Close engine driven hydraulic shut-off valve Depressurizes engine driven pump |
|
|
|
What systems does the LEFT hydraulic system power? (6) |
Spoilers Ailerons Flaperons Elevator Rudder Left thrust reverser |
|
|
|
What pressurizes the hydraulic reservoirs? |
Bleed Air |
|
|
|
What systems does the RIGHT hydraulic system power? (7) |
Spoilers Flaperons Elevator Rudder Right thrust reverser Right Stab trim Normal braking |
|
|
|
What does the CENTER hydraulic system power? (7) |
Flight Controls Leading edge slats Trailing edge flaps Landing gear retraction Alternate brakes Nose wheel steering Main gear steering |
|
|
|
What does the RAT hydraulically power when deployed? |
Primary flight controls only |
|
|
|
On the ground when will the primary C2 pump be load shed when C1 pump is also selected? |
When a single ground power source is connected OR APU only. |
|
|
|
In flight when will the primary C2 pump be load shed when C1 pump is also selected? |
When all other electric pumps are running OR Single source of electrical power OR Generator capacity is exceeded |
|
|
|
What happens when BOTH C1 and C2 demand pumps are selected to ON? |
Both pumps can not run simultaneously resulting in C1 demand operating. |
|
|
|
If center hydraulic system fluid is sensed to be low and airspeed is greater than 60 knots what happens? |
Alternate breaks are isolated from the center system and remain operable using reserve fluid Nose gear actuation and steering are isolated Leading edge slats are isolated and not allowed to operate in the primary mode |
|
|
|
After shutting off when are slats reconnected and allowed to operate in the primary mode and when does the nose gear actuation and steering become operable? |
When center hydraulic fluid recovers to normal for 5 seconds and both engines have been running for 30 seconds
Airspeed below 60 knots OR
Hydraulic pressure to the center system flight controls is low OR
The landing gear lever is selected down, both engines are normal and both engine driven pumps are providing pressure. |
|
|
|
What is the purpose of the demand pumps? |
Additional hydraulic power during high system demand and back-up source |
|
