I'm just curious. Since they rejected the planned engine because it could not guarantee to meet the perfromance requirement, and a decision on which of the new paper engines being proposed will not be made till next month, how any one can be so precise in the figures?
And, of course, any new engine is a risk. Take, as an example, the PW6000, which is slipping to the right as it continues to exceed guaranteed fuel performance figures by around 6%.
I believe the PW6000 shares a common technology core with the PW800, which provides the core of their proposed engine for the A400M.......
