. Max fuel flow should be closer to 27 gph, but it seems to be maxed at 22. It looks to me that inclusion of the SR22 is a rush job that should have been held back until properly tested. Then Torquesim SR22 on Xplane is much more realistic.
I fly my own SR22 (real not sim) and you need the mixture control in order to fly lean of peak EGT. That is how Cirrus owners fly their aircraft in order to maintain clean engines and conserve fuel.
The mixture control does not seem to work properly. If you reduce it nothing happens at first until it is almost extended at which point the fuel flow drops suddenly. You cannot set fuel flow at some intermediate stage. Also the AP is faulty in many respects. I have given up on this aircraft. On the other hand something like the C172 works fine.
