Fuel System Flashcards
How many pounds of useable fuel does the single-point refueling system provide?
3906 LBS
How many pounds of useable fuel does the single point refueling system provide for the right system and the left system?
1990 lbs in the right system
1916 pounds in the left system
How many pounds of “over-the-top” is available for useable fuel?
3866 lbs
If your aircraft is being filled using over-the-top fueling, which side must be fueled first and why?
The left side to prevent the airplane sitting on its tail
Where is all fuel carried in the T38?
It is carried in five fuel cells, all of which is carried in the fuselage, aft of the cockpit and forward of the engines
What does the left fuel system consist of?
It consist of two dorsal cells and the forward fuselage cell, these cells normally supply the left engine
Does the left fuel system refer to its physical locaiton of the components that it supplies?
To the components it supplies
What fuel cells comprise the right fuel system?
The center and aft fuselage cells
What components of the T38 does the right fuel system service?
They supply fuel to the right engine
How does each of the fuel cells vent?
They all vent overboard through a common vent located in the vertical tail just above the rudder.
What prevents the loss of fuel due ot aircraft attitude and ambient temperatures?
Check valves located within the fuel system
What does the vent system pressure relief valve do?
It allows fuel to vent overboard in the event of thermal expansion
How is fuel capacity determined?
The capacitance system uses the dielectric properites of fuel. As the quantity of fuel varies, the total electrical capacitance varies in proporiton. This proportion determing the amount of fuel remaining.
Does the fuel system compensate for changes in fuel density?
Yes
How many capacitance probes are in the fuel cells?
7
Does the EED display total fuel or the useable fuel?
Useable fuel
When does the FUEL LOW light come on?
It illuminates after a 7.5 second delay when either fuel quanitity indicator reads below 250 pounds
