The PMS seems to give a climb EPR that is much higher than the maximum climb EPR from the table on the FEs desk. In this example I am at FL260, with a TAT of 3 degrees. According to the maximum climb chart this should give me an EPR of around .640, however the PMS gives me a climb EPR of .716.

 

Thanks, forwarded to the team for further investigation.

Are those charts for the -500? I do not believe the N1 and EPR readings are correctly synced. I am going back about 45 years now but I recall seeing N1 values of 93% at a 350FL cruise.  The N1 value should be between about 84 to 89/90. INI readings are about 79/80/
