QF interest in SYD-LON 777-200LR

[hangar 9]

The discussion is about B777 not B744 and although the waste tanks don't appear to be large. When they are full of waste and stored in the rear of the aircraft it has a significant effect on the load ( C.G.) and fuel for landing. Fuel used to be stored in rubber bladders and fuel leaks were very rare, so with a collapsible bladder situated towards the middle of the aircaft it is a very real and feasible solution to reducing fuel burn. This coupled with a system of siphoning of fliuds and dispersing them at altitude also reduces fuel burn. In aircraft 20 years ago systems of waste filtration argueabley could produce flush water that was pure enough to drink. Therefore enviromentally it would also not create a problem.

Little note in this month's Airliner World (top of p.22) says Qantas is in discussions with Boeing about an order for 30 but is "currently completing a technical audit of the new B777-200LR before confirming its exact requirements".

Any ideas/updates on timing of order announcement?

Sorry if this has been done to death elsewhere; I took a look but couldn't find anything recent.

Thanks
