All
have we overlooked the fact that with a 2 engined aircraft you only have to overhaul 2 engines at say $3-4 million a piece on a 777, when on the A340 you have to shop visit 4 engines at say $2-3 million. B777 = $7 million, A340 $10 million. Approximate figures used, terms and conditions may apply, the value of your A340 may go up as well as down!
And, with the CFM haridryer's having just enough thrust and EGT margin to pull the skin off a rice pudding you will be shop-visiting more often than say it's bulletproof GE90 big-brother.
So perhaps the comments were leaning more towards the bean counters who love twin engined a/c because of the above. My current operator, spend 1/3 of the engineering budget on the noise generators.
Thoughts?
