Fuel Tank Inerting - Vent System

[Fargoo]

p.s. I believe it is soon to be FAA mandated on aircraft in US airspace, can't remember the date for this though - anyone?

Makes Honeywell money

Thanks.

However, Honeywell is the seller and not the buyer.

My interest is to learn from the buyers why would they spend their good money to buy and install a nitrogen Fuel tank inerting system on their plane or their fleet. These systems are expensive. There must be something good about them. I have failed to find anything to write home about. They are not required by law. Also, I will love to learn from the sellers why are they peddling such a system.

Please post your reasons.

Thanks.

Mandated

The regulation requires a Flammability Reduction System. It is performance based. No particular System has been mandated. A few articles stated that inerting is mandated. It is not true. Read the Final rule on FAA website or in the Federal Register.

Seems like you already know all the answers.

EASA are also expected to mandate installation of a Flammability reduction system.

Whether it's an inert gas or some other system the regulation is expected by the end of the year.

Hey guys,

Sorry for bringing up such a dated thread, but I find the whole NGS quite intriguing, given that Boeing does not supply us with much information in our manuals!

The case is that some time back I remember watching a 20 minute or so video which explains the NGS on the 737.

Can anyone provide me with a link for this??? Iīve been searching for it but I just canīt seem to find it!

Many thanks.

I am curious as to why a nitrogen generating system would be shut down for such situations as a forward compartment fire or an engine shutdown.

The russian planes of ww2 ran a portion of exhaust into fuel tanks to reduce chances of fire

Cseries tank inerting system is separate from the vent system. The vent system is no different to any other. The inerting system is always on(when bleed is available) the flow rate varies with phase of flight but it's always pumping and the tanks are always venting.
