Hi Jacques, Kinetic Energy calculation always needs airspeed and yes therefore XCS must be hooked up to an instrument which can deliver this value and then it considers it in the calculation.
Using GPS Ground speed does not work - just imaging having GS of ca. 0 (eg. wave flying) the kin. energy would be 0 which would be incorrect. Cheers Sascha PS: This is another topic from th originallay discussed topic of A) arrival heights B) L/D calc. Maybe to possibly avoid confusion lets open another thread.
