|
What is the purpose of a fuel dump system? |
So that the flight crew can quickly bring the weight of the airplane down to the maximum landing weight if an emergency occurs during or shortly after takeoff. |
|
|
Other than reducing weight, what other function can be accomplished with a fuel jettisoning system? |
Fuel can be dumped from the heavy wing in order to maintain lateral stability. |
|
|
What are a few types of fuel cells? |
Bladder-type, integral type fuel cells, integral fuel tanks, welded or riveted fuel tanks. |
|
|
How is the weight of a bladder-type fuel cell supported? |
the structure of the cavity in which it sits. |
|
|
What is "wet wing" construction? |
When the fuel cells are built into the wings of the aircraft structure using the skin to contain the fuel.(integral fuel cells) |
|
|
What are the advantages of a single point pressure fueling system? |
Greatly reduces the time required to service large aircraft. It eliminates aircraft skin damage from hoses and hose nozzles, and reduces the chance of fuel contamination. |
|
|
What is the purpose of a fuel temperature indicator on a turbine engine? |
Determine when there may be danger of ice crystals forming in the fuel. |
|
|
What is the purpose of warning lights in connection with fuel systems? |
indicate when the fuel pressure is too low, or to indicate when the fuel quantity in a tank is below a certain amount. |
|
|
Where are electrical operated valve-in-transit indicator lights used? |
Each of the fuel crossfeed and line valves |
|
|
What are four general types of fuel quantity gauges? |
Sight glass, Mechanical, electrical, and electronic. |
|
|
Which type fuel quantity gauge is considered to be more accurate than the other types? |
Electronic-capacitance type because it measures by weight |
|
|
What is a drip gauge? |
An under-wing bayonet type fuel gauge that consists of a hollow drip tube that is drawn out from the lower wing surface. Fuel enters the top of the tube when it reaches the level of the fuel. |
|
|
What is a crossfeed system? |
An interconnected fuel system designed so that fuel can be fed from any tank to any engine. |
|
|
What is the purpose of the baffles in a fuel tank? |
To prevent the fuel from surging as a result of changes in attitude of the aircraft. |
|
|
How can a fuel tank be checked for leaks after a repair? |
By a pressure check using air pressure not over one-half psi with liquid soap or bubble solution to identify the leak. |
