As many airlines use the CFM56-7B22 in the -700, I would like to know if there is a way to get the FMC in the -700 to use the 22k rated engine data (same as default-600). If it cannot be changed directly, perhaps a indirect method such as altering a line in the cfg or air file, etc. Thanks for any suggestions. Steve B. ATP 737

Or 24K for that matter, since that's the Transavia engine rating for the -700s.
