Fuel Flashcards
What temperature where fuels start to crystallize?
Freezing point
Cavity located in wing tip to compensate overflowing fuel and facilitate ventilation
Vent surge tank
What component do we install at the end of refueling line in order to soften the high refueling pressure
Diffuser
What defueling method where you are using the tank boost pump to defuel tank
Pressure defueling
What specific aircraft tank is used to increase the aerodynamic efficiency of an aircraft in flight by means of shifting the fuel weight
Trim tank
Where do you see auxiliary tanks
Cargo
Where do you see trim tanks
Horizontal stabilizer
Where do you see integral tanks
Wings
Cylinder bottle ng gaseous oxygen
PSU
During emergency this facilities used to dump the fuel overboard to prevent exceeding the maximum landing weight
Jettison
Jet fuel used for commercial operations
Jet A and Jet A1
Jet fuel that has the highest freezing point
Jet A
Lowest freezing point
Jet B
Highest flashpoint
JP 5
Lowest flashpoint
Jet B
Flashpoint of Jet A1 and Jet A
38 degC
Freezing point of Jet A1
-47 degC
Characteristic of fuel where it has the ability to vaporize
Volatility
What is flashpoint
Lowest temperature of fuel at which fuel creates just enough vapors to build up fuel/air mixture that can be inflamed
What is the density of Jet A1 and Jet A at 15 degC?
0.81 kg/L
Type of drain valve that uses a drain line that runs from the lowest point in the fuel tank to the valve housing
Indirect drain valve
Allows air in the fuel tank to escape during refueling
Vent system
Prevent fuel entering vent system at any aircraft attitude
Float valve
Refueling by using an external pump and hose to the overwing filler ports
Gravity refueling
