I'm not sure yet. Now that my internet connection is back up I'm trying to find out what exactly is the problem that Hans-Georg is having. I need specifics. An overview of how FGTurbine calculates thrust and fuel flow: Idle thrust is looked up in the idle thrust table, which uses speed and altitude as inputs. Full thrust (military thrust) is looked up in the milthrust table, also using speed and altitude as inputs. Idle thrust is subtracted from this here. It is added back in later. N1 and N2 targets are based on the throttle position and the idle N1 and idle N2 values from the configuration file. A function called Seek() acts as a lag filter to spin the engine to the target N1 and N2 realisticaly. A value called N2norm is found. This is just the N2 range (from idle N2 to maximum N2) normalized. A "thrust coefficient" is found, ... Oops, that's not my code. It looks like we're getting thrust squared? I'll fix it.
