2. Cyan FUEL BOOST PUMP L/R

19
Q

Do you need Main DC Bus power to supply fuel to the engines?

A 
No
Main DC power is required during:
1. Start
2. Low Fuel Pressure 
3. X-FEED
20
Q

When are the Pre-Check levers normally used?

A
  1. When checking the SPR automatic shutoff valves

2. De-Fueling

21
Q

25
Q

What triggers the FUEL LOW STBY annunciator and the CAS message?

A

Float switch

26
Q

What technique is used to preflight the X-FEED?
