Ilyushin IL-86 template for PFPX. Accuracy of calculations - 95-98%, main source - IL-86 Flight Operations Manual. Main climb and descend modes are done, and only LRC for cruise. Also you need to choose your Flight Level and Mach number according to the tables, which are in archive, cause PFPX is not able to choose FL correctly. Only ISA conditions. I'm sure this profile is pretty accurate for flying in FlightSim, all calculations were checked and compared with examples in Flight Operation Manual. Long live - soviet "Airbus"!
