FLIGHT-X
State of the Art Aircraft Flight
A multi-disciplinary software system has been developed over the past 15 years to address engineering problems of performance capability, commercial viability, sustainable environmental and responsible aviation.
Over the years, FLIGHT-X it has been continuously verified, tested and applied to a variety of aviation projects. The core software has been documented in a large number of books, peer-review papers, international conferences, CPD courses, and other outlets.
An aerospace database has been developed in the process, including airplanes, aero-engines, APU, landing-gear systems, high-lift systems, helicopters, airfield models, flight data recorder data packs, ADS-B flight trajectories.
