View Full Version : Fuel inerting means more fuel capacity?

A recent article by Aviation International News about the new Dassault business jet 6X stated

"The 6Xs mtow will be 77,460 pounds. It will also have a 300-nm range increase over the 5Xto 5,500 nmand first deliveries are scheduled for 2022. The extra fuel required for the additional range caused Dassault to switch to a nitrogen-based fuel pressurization system, a first for a business jet."

Does this mean there is less plumbing in a nitrogen based fuel pressurizatin system, and this is why more fuel can be carried?

I'm not sure why the increased range would cause Dassault to install a tank inert system unless it is a regulatory requirement. You actually more space for the hardware for the system (outside of the tank) - the plumbing inside is pretty identical.

i would not understand the sentence the way you do.
it just says there is more fuel so they switched to an inerting system. (still does not make much sense in my opionion)

this pdf from dassault only praised the added safety. maybe they introduced a tank that would be almost empty most of the time (one of the main problems causing fuel tank explosions as you can read in the link from gearlever)

OK thanks. I think he text from Dassault may have misled me. Hawk.
