Fuel System Flashcards
Pressure refuel quantity?
14,150 lbs
Gravity/overwing refuel quantity?
13,000 lbs
Fuel tanks are divided into how many sections?
3 sections - main tank, collector tank, and surge tank
What ways are there to laterally transfer fuel between wing tanks?
Transfer(XFER) – via DC boost pumps
Gravity XFlow
How do you transfer fuel from the left wing to the right wing?
- Left DC boost pump on
2. xfer open
How do you transfer fuel from the left to right on the ground with engines off and APU running?
- Left DC pump on
- xfer open
- Rt. pump off.
(Not documented as an approved procedure by Bombardier)
How is the fuel heated?
Fuel / Oil Heat Exchanger
Do you need battery power to fuel the aircraft?
Yes.
Fuel / Defuel SOV are powered by the Rt. Battery bus.
Is mixing of fuel types approved?
Yes
What part of the fuel tank supplies fuel to the engines?
Collector Tank
What is the function of the surge tank at the tip of the fuel tanks?
To provide additional expansion volume for the vent system
What operates the Main Ejector and Scavenge Ejectors?
Motive flow from the engine driven pumps
Minimum wing fuel for go-around?
500 lbs per side
Do we need fuel anti-icing additive as long as the minimum oil temperature is achieved?
No, Fuel is heated thru the fuel/oil heat exchangers
How many water drains are in the fuel tanks?
6
When do we drain the fuel tanks?
When contamination is suspected
How many fuel pumps are on the CL350/300? 9
9 TOTAL engine driven pumps(2), electric boost pumps(2), main ejectors(2), scavenge ejectors(2) APU mechanical pump(1)
The powered fuel transfer valve fails to open, what is the backup way of moving fuel between the wing tanks?
Gravity transfer
In “AUTO” when do the electric fuel pumps come on?
Run switch to “RUN” - for engine start
Low fuel pressure indication
Right pump for APU operation when right engine is not running
How many fuel quantity probes are there?
9 per wing
FUEL QTY LOW CAS occurs when?
300 lbs or less in a wing.
Single point refuel pressure is limited to?
55 psig
The fuel/oil heat exchanger is where?
The AGB
The Hydraulic/fuel heat exchanger is where?
Fuel tank
When the fuel temp is approaching 45 to 50 degrees what consideration should be made?
Limitations regarding maximum fuel temp and minimum fuel level in order to cool hydraulic fluid through the hydraulic/fuel heat exchanger.
