Turbine D,
No, I'm not... if you check the specs of the Leap X and the CFM 56-7..the bypass ratio on the Leap X is going to be higher that the old engine..meaning a higher fan diameter...+ new engine casing and nacelle
If Boeing installs the Leap X as it is right now...it would hit the nacelle on the ground...Airbus on the other hand...the nacelle/engine casing for the Leap X would give a few inches of ground clearance..
