Re: Negligent certification

As I understand it, the fundamental change was more fuel efficient engines. However these if placed in the logical place would have scarped along the tarmac.

So they were moved forward and cranked up a bit.

Changing the CG and the on thrust/off thrust trim by such an extent they put some software in to correct for it.

So downtrim when the throttles are opened, giving a massive nose down if the throttles are chopped. Before the trim returns to 'glide'

This was bunged in the anti stall software I think.
