Aircraft Airfile Manager (AAM) has been reborn for MSFS 2020 thanks to Karl-Heinz Klotz. Karl simplified editing the .air files for fs9, fsx, and P3D. You can now easily edit your flight_model.cfg and engines.cfg on the fly. Once again you can view your tables graphicly and adjust your values by simply dragging points on a graph. Available on flightsim.to as freeware! Thank you Karl!
