14% efficiency gains by moving the engines 8 inches?

I’m not a pilot. Just a mechanical engineer who’s an armchair quarterback.

I come here when I need facts on air incidents.

A 14% increase in fuel efficiency from a simple move like that indicates vastly different aerodynamic performance. How much does bypass ratio add? How much does adding an extra row of compressor blades increase performance?

this indicates that there are some interesting boundary layer effects happening to this aircraft. I’m curious if somehow there are vortexes being generated at higher AoAs that somehow interfere with the pitot tubes.

Bring the wrath. I know I’m just an observer.
