COMAC C919 Misrepresentation (as usual)

Actually no, I don’t. I still want that western v.s. non-western list to be convinced. I see many issues on aircraft performance: airport location impact (height temperature etc), fuel consumption, ETOPS rules, etc; what you are suggesting is not one of them so far. So I need solid proof to be shown.

If you read the reply on your topic

you know what’s the right way. Please don’t expect anyone to do anything right away for you. I have concerns addressed in support tickets, and it took years for some of them to be improved or addressed. And I’m sure they have their own priority. Please don’t expect you to get anything in the way you want.
