Looking at the cert for the T900
http://rgl.faa.gov/Regulatory_and_Gu...E/E00075EN.pdf I'm reading that the basic continuous max thrust for everything in the family is 71,850 lbs.
The difference is in the T/O thrust for the different variants - from 71,152 to 84,098 lbs.
The engine itself is apparently identical, and these different ratings are "plug" controlled.
So what makes the operation different?
Thanks in advance!
