Question 1

FUEL TANK INERTING SYSTEM is to reduce the flammability in the fuel tanks that have

Answer 1

a high flammability exposure.

The fuel center tank is the only one that has a high flammability exposure. Therefore, the Fuel Tank Inerting System only needs to be installed for the center tank. All other tanks do not need Fuel Tank Inerting System installation.

Question 2

To reduce the flammability in the center tank, the Fuel Tank Inerting System produces

Answer 2

an oxygen-depleted air that goes in the center tank to replace the ambient air.

Therefore, an oxygen-depleted air is produced (with less than 12 % of oxygen) and replaces the ambient air of the center tank.

Question 3

FUEL TANK INERTING SYSTEM
The system is installed in the belly fairing of the aircraft, and is composed by:

Answer 3

‐ A Conditioned Service Air System (CSAS)
‐ An Inert Gas Generation System (IGGS).

The Fuel Tank Inerting System does not require any flight crew action. It works independently as soon as the engines start and until they stop.
