That is proprietary information, not sure TBC would be dishing that out, but there is reasonableness that comes from renting a MAX sim and doing a QTG flyout. The margins permitted for an approved simulator are quite large but will give some semblance of the polar, at least within normal envelope, and will give a fair answer on control loads, and derivatives. Getting hands on the QTG cards themselves is probably going to be frowned on, they are still proprietary information. The sims aren't the M-CAB or the real thing. The airline operators have accurate information from the parameters that are being pulled for the QAR data for monitoring, W/delta is a pain from line data, you need a stack of it to get a statistically significant performance set unless you have some exact data points from the OPM and digital performance DB.
I was referring to the ones who wrote a report on their fix. It's not proprietary to them and no information from TBC required.
