Currently we have achieved satisfactory flight dynamics parameters resulting from payload, fuel quantity, aerodynamic surfaces (wings, fin, horizontal stabilizer) and main gear. Any changes of payload or fuel affect the center of gravity horizontally and vertically which in turn changes inertia, controllability and balance state of the helicopter in flight.
Overall, the AH-64D Flight Modeling is step by step approaching an excellent level of “realism” and our SMEs are enthusiastic with the results to date. Each and every correction or modification step in the flight model (tail rotor characteristics change for instance) requires another run of the checks for balancing characteristics and flight dynamics. Because of that we are constantly doing test flights and correcting inaccuracies.
