Fuel Tank Inerting System (FTIS)

Flight Operations | Applicability: Airbus fleet

Airbus Aircraft Family: A320 | A330 | A340

On July 21th, 2008, the FAA required operators and manufacturers to incorporate a Flammability Reduction Means (FRM) or ignition mitigation means on fuel tanks having a flammability exposure exceeding certain thresholds. These amendments affect new aircraft types, new aircraft in production and in-service aircraft produced after January 1st, 1992.

 The system is fitted as standard on line fit aircraft today.

The FAA were the first authority to propose a mandate for In Service aircraft and this was subsequently followed by other local authorities. The Chinese authorities also now require full fleet compliance by 2024.

The sytem conditions air from the engine bleed prior to passing it through an Inert Gas Generating System before entry into the aircraft Centre Fuel Tank.
