FE Hoppy,

Drag goes up, assuming they're on the backside of the power curve. But how does drag going up increase the kinetic energy of the air entering the engine? The engines breath clean, undisturbed air if they're hanging below the wings - which means the speed of the air is the main factor.

How do you know FADEC doesn't have anything to do with this? The thrust lever isn't connected to a manual fuel valve, it goes through the FADEC computer. I don't think you can rule out the FADEC computer from this issue.
