Karen's Quiz-Falcon 900EasyLX-Part 3-Pneumatics Flashcards
Where do you find Pneumatic Info
CODE 1 ATA 36/Air Conditioning/Pressurization
CODE1 ATA 21
What controls pressurization and temp on the plane
BASC Bleed Air System Computer
What does the optional ABOC do?
Automatic Bleed Air Overide Controller
Allows auto closure of HP valve when at hight thrust
and assurs LP bleed for wings and S-duct heat
provides better performance when eng & wing AI is on
What happes when ISO rotary switch is engaged?
closes isolation valved to divide the manifold into 2 seperate systems
When ISO valve is closed, what is providing bleed heat to the cockpit?
Bleed from No 1 and No 3 engines
When ISO valve is closed, what is providing bleed heat to the cabin?
Bleed from No 2 engine and APU on the ground
Can passenger and crew conditioning ducts be interconnected?
Yes, there is an inter-connect valve located on the lower right hand side of the aft cabin area
What is the function of the REMOTE soft key?
Allows passenger cabin temp to be adjusted . It is on the aft cabin LED controller
When would I use manual mode to control Pax/Crew temperature?
When auto mode is not working
How do you operate pax/crew temp manually
Rotactor switch all the way counterclockwise till it clicks. Cold Hot buttons are used to control temp and monitor
on Synoptics
what are 2 main laws of operation for Pressurization
Normal NORM and Flight Level FL
What is NORM normal law?
provides most comfortable pressure mode by limiting rate of cabin pressure during climb and descent
What is FL Flight Level law?
better for flights at lower altitude. maintains a cabin altitude of 1000ft to FL230 and then quickly tries to catch up on schedule
What is the LOW soft key for?
Limits rate of change from 500/-300feet per min instead of 650/-400
