solution– Expert Verified | Latest Version | 100 Guaranteed
Success
How much nominal PSI do the Systems Deliver? - 3000 psi
How much nominal PSI does the RAT Deliver? - 2850 psi
What Compenets use Hydrulic power? - 1.) Primary Flight Controls
2.) Seconday Flight Controls
3.) Thrust Reversers
4.) Landing Gear
5.) Nosewheel Steering
6.) Ram Air Turbine (stow actuator)
How many Hydraulic pumps are there? - 7 (including PTU)
What is the difference between System 1 and System 2? - System 1 Reservoir
Capacity is bigger.
System 1 Backup Pump- PTU
System 2 Backup Pump- ACMP 2B
3 Ways to Shutoff Hydraulic SOV - 1.) HYD SOV Button
2.) Fire Pushbutton
, 3.) Automatic when HYD Fluid Temp = 125°C
When does the PTU come on in AUTO? - "SHE"
1.) Single Engine Taxi (Right-Engine)
2.) High Demand
3.) EDP 1A Failure
What Conditions need to exist for the PTU to operate automatically? - 1.) No
Overheat (<107°F)
2.) No. 1 has more than 5% HYD Fluid.
When does the ACMP 2B come on in AUTO? - "SHE"
1.) Single Engine Taxi (Left-Engine)
2.) High Demand
3.) EDP 2A Failure
What is considered High Demand? - 1.) Takeoff Thrust
2.) Flap 4 or 5 or ALT/FLAP
3.) Engine Fail Inflight
-PTU = Left
-ACMP 2B= Right
Why turn on the HYD Pump during Single Engine Taxi? - To protect actuators and
prevent:
SLOW RATE (cyan) EICAS message.
