Unmanned Transport:
Its a good thing Xmas is coming because you seriously need to get a clue.

Air Canada chose the the GenX for a purely financial reason: GE 'gave away' that engine to get a major NA customer on board.

The Trent 1000 is the technological favourite - that is why ANA chose them over GenX and why Northwest, which originally chose GenX, went over to Trent 1000.

The Trent 8104 was out before the GE90-115B, but GE bought their way into the 777X program (and copied alot of 8104 technology). On the 200 series 777, the Trent 800 is the Worldwide favorite. As is the Trent 700 on the A330.

PW put NO PARTS on the GenX, you're confusing the GP7200 on the A380 where PW and GE have teamed up.

As far as the Trent 900 goes - hey at least its on the A380 now, which is not the case for the GP7200. The problems on the 900 are small compared to the delays on the GP7200 ie. failed fan blade off test.

Please stick to what you know.....

Don't even get me started on your warped view of how a triple spool works...

ac pension question
 

Since the topic got skewed onto AC's financials, I'm curious.....

How much did AC owe to the employee pension plan(s) going into bankruptcy protection?

How much do they owe now?

Could be millions. Could be billions. Under Canadian law, AC has to pay it back. They have ten years to do that. It's the law. What's there is suffiient and protected. Not losing any sleep over it in case you're wondering. :ok:
