This standard should provide accurate fuel consumption prediction methods throughout the flight regime. The standard should apply to any fixed-wing, turbofan or turbojet-powered airplane.
Several competing methodolgies currently exist for estimating the fuel consumption of airplanes. The standard should provide guidance of the usage and limitations of these methods, and well as consider the development of new methods, if required. The standard should provide a method or methods of predicting fuel consumption of airplanes based on the known state or parameters of an airplane at any point in flight. Note that accurate fuel consumption information is also required for the prediction of airplane emissions.
