What MFD page provides a visual representation of the hydraulic system operation and parameters?
Hydraulic synoptic page.
An amber tick marker is placed at the position relative to what pressure?
1800 psi.
What color is the symbol for SOVs that are open, EDPs that are on and flow lines that are pressurized?
Green.
Will a failure of two hydraulic systems result in a complete loss of flight critical functions?
No.
What is hydraulic system 1 comprised of?
EDP, DCMP, SOV, reservoir, and accumulator.
(DCMP … DC Motor Pump)
When will the DCMP1 be automatically commanded on with the HYD 1 ELEC PUMP knob in the AUTO position?
During takeoff and landing phases.
What is hydraulic system 2 comprised of?
EDP, SOV, reservoir, and accumulator.
What is hydraulic system 3 comprised of?
