E or X?
I always thought that the "X" suffix was for the Advanced/Enhanced versions of the A332/3 and A342/3.
Now Wiki says its "E" not "X".
Went on Airbus site to confrim and I see "E" suffix for Advanced/Enhanced nomenclature.
This is the generic commercial designation as the QRH does not mention the "E" or "X" but simply Advanced.
