This one includes a performance and template file for the RealAir Turbine Duke. All the values have been taken from Prepar3D, so, they are authentic values.
The performance data only includes a cruise profile at 92-95% N1 RPM, that is the most common profile with this aircraft, also with -10/+10 ISA deviation data, and two different payload configurations. Some other profiles has been considered, but not very relevant to be included. The file has been tested with a couple of flights using PFPX. The fuel calculation has been very good.
The template is designed to be used with the Flight1 GTN 750. If you don't have that, you only need to change the equipment of the aircraft. The only practical difference should the type of transponder, and no ADS-B capability.
