Re: Boeing 717 - loudest interior cabin noise level ever!

I was just on an AA MD-80 on Friday and I noticed a few things: 1) Flow from my gasper vent definitely varied with engine RPM. 2) I didn't hear a lot of engine noise up in the bulkhead row of Y, but man was the slipstream loud once we got up to speed. By contrast, on approach it was almost like we ...

I believe the maintenance check intervals for some structural inspections change (become more frequent or stringent) as a result of higher weight.

Re: Which aircraft has the advantage - A350-900ULR v 772LR.

Back the OP question...which has the advantage?

It's not even a fair question imho, other than at extreme range. The 777LR OEW is much greater than the A350, and the engines are 10+years older on the 777LR. The 350 has a huge advantage on 90%of likely city pairs.

Scrapping an airplane is not as simple as it sounds. For example, the elevator counterweights in the L1010 were made from depleted uranium. The fuel densitometers in the 757/767 have a radioactive material in them. Perhaps Iran lacks the technical capability to scrap them properly?
