"It's just a difference between what the thrust moods actually do, because in our 145's, T/O is the same as T/O RSV in the 140 / 135, and there is no such thing as E-T/O RSV.
Just splitting hairs, but thought I'd point it out."

E-TO RSV is in reference in CFM to the A1E engine only on the 145XR
If I remember correctly from what I was told by actual pilots is that the XR has slightly different thrust management...I think. ahhhhh poooy, I forgot what someone told me already. Anyway thanks for all the input, it does help me out. Cheers!
