Re: Why is the A343 "underpowered"?

The CFM-56-5C was tested to 36,000+ lbs and I'm sure it would not have taken much to certify it at that rating. Obviously Airbus didn't feel that they needed to.

Well, considering the GE90-90B (90k thrust variant) weighs 17,400 lbs and the GE CF6-80E1 weighs 11,200 lbs, I can see why Airbus would be rolling their eyes. Only a serious stretch of the 333 could make that weight penalty worth the fuel burn savings. Taller landing gear may also be required...

Re: Airbus weighs response if Boeing launches new mid-market model

The only course that really makes sense for Boeing is to address MOM with a version of their 737 replacement (NSA). This shouldn't be too hard as the optimum size for both the 737 and 320 keeps moving up. A318, A319, 737-600/7 are basically non-factors.. NSA will probably start with 738/A320 size an...

Based on 767-200 non-ER max TO weight and engine thrust, I'd think a 150 ton MOM would need at least 50,000 lb engines unless the wing area is substantially larger than the 767's 3050 sq ft (which of course would add more weight)

They won't stop producing the 747-8F until there is a real one-for one replacement, which the proposed 777-8F is not. I'll bet even money that if they threaten to close the line before then, there will be a flurry of orders to "get one while they can", ...resulting in continued production.
