737-NG 27K BUMP
Does anyone have technical info regarding the 'bump'? Does it revert to 26K automatically at 1500'agl? How much more ALT capability might you expect from a 27K engine over a 26K one? Are there only two derates available through the FMC? ie if you have 27K engines, only 26K and 24K are derate options? If you were buying an NG with an option for 27K full rated engines or Bump engines which would you choose and why?. .One last question, has anyone had any experience with the CFM 56-3 DAC, rather than the SAC, on the NG? Any good or not?
