CFM56 -2 OIL SYSTEM QUESTION
A question for a proper spanner god, does the CFM56 oil system (specifically -2 model, but I doubt they differ greatly) use supply oil for the pressure gauge pick-off, or supply v sump px? I suspect the latter, from checking pipework, yet find no reference in my tech pubs ( a reference would be appreciated, Google has not really helped so far...). What is the advantage or benefit of using supply v sump as the indication? - I believe the 211 uses the latter as well?
Thanks for any help!
