Fuel Tank Safety

What is Fuel Tank Safety?

• a critical aspect of aircraft design, maintenance, and operation that aims to prevent fuel-related accidents, such as leaks, fires, or explosions.

• improve to increase fuel range

• improve to decrease the flight safety

What are key factors to contribute Fuel Tank Safety? (select all that apply)

• Design and Construction

• Fuel System Components

• Fueling Procedures

• Fuel Tank Ventilation

What is the most appropriate definition of Fuel Tank Inerting?

• Inerting systems are installed in aircraft fuel tanks to reduce the risk of fire or explosion by replacing oxygen with inert gas (such as nitrogen) to maintain a non-flammable atmosphere within the tank.

• prevents oxidation or moisture contamination

• process of converting a substance from a flammable or reactive condition into a safe, non-flammable or non-reactive state

Refresher course for Fuel Tank Safety must be undertaken every _____ years?

• 5

• 2

• 4

• 1

What is the definition of flammability?

• Is the ease with which a material is ignited, the intensity with which it burns and releases heat once ignited, its propensity to spread fire, and the rate at which it generates smoke and toxic combustion products during gasification and burning.

• a measure of how low specific material is capable of catching fire and burning.

What is Ullage in tank?

• volume which is left empty in a tank so that there is space for the liquid in the tank to expand. The air space between the fuel surface and the top of the tank
