Hydraulic System Flashcards
Hydraulic System Pressure?
3000 psi
What is normal reservoir quantity?
45% to 85%
If the reservoir is outside of its normal range, what color will the digital quantity be displayed in?
White
What type of hydraulic fluid do we use?
Skydrol - Color purple
If pump 1a or 2a fails, will the respective electric pump activate automatically?
No
When will the electric pump (ACMP’s) automatically activate?
With their switches in auto, at least one generator online and flap position greater than zero.
How are hydraulic systems 1 and 2 cooled? How is hydraulic system 3 cooled?
Systems 1 and 2 are cooled by ram air in flight, and ram air duct fan on ground. Blows cool air over heat exchanger in aft equipment bay.
System 3 naturally cools
If there is an engine driven pump failure, must the associated hydraulic pump be shut down?
No
When will hydraulic 1 or 2 HI TEMP caution be displayed?
When temps exceed 96’ celcius
When a powered hydraulic system is displayed in white on the hydraulic synoptic page, what is indicated?
The system is pressurized above 1800 psi
What is indicated when a system is displayed in amber?
The system is pressurized less than 1800 psi
What is indicated when a system is displayed in a muted (dim) magenta?
The sensing system is receiving invalid data
Which pumps are not controlled by the hydraulic control panel?
1A 2A
What powers hydraulic pump 3B?
AC Bus 1, ADG when deployed
If the ADG is providing power to 3B, can it be manually turned off?
No switch will not work
