Aircraft simulation is a powerful tool for accident investigation. For cases where the number of flight data recorder (FDR) parameters are limited, the Safety Board has used simulation and its inverse (kinematics extraction) to extract non-recorded control time histories from aircraft motion. For cases where there is radar data but no FDR data, simulation can eliminate some failures from the list of possible causes and can be used to find control time histories that do match the accident. An example of this is seen in the study of the Silkair MI185 accident. In the investigation of the THY flight 5904 accident, only short segments of FDR tape were recovered. A simulation was done that matched the FDR data during the times when FDR data was available and flew through radar data during time periods between FDR tape segments.
The objective of this paper is to show a complete simulation of multiple Unmanned Air Vehicles (UAVs), with emphasis on the requirements needed and the benefits realized in making the simulation functional for an arbi...

The use of flight simulation tools to reduce the schedule, risk, and required amount of flight testing for complex aerospace systems is a well-recognized benefit of these approaches. However, some special challenges arise when one attempts to obtain these benefits for the development and operation of an Experimental Uninhabited Aerial Vehicle (UAV) system. These types of UAV systems are characterized by the need for the need for continual checkout of experimental software and hardware. Also, flight-testing can be further leveraged by complementing research results with flight-test validated simulation results for the same experimental UAV. In this paper, flight simulation architectures for system design, integration, and operation of an experimental helicopter-based UAV, the GTMax, are explored, and the development of a simulation tool described. The chosen helicopter-based UAV platform (a Yamaha R-Max) is well instrumented: differential GPS, inertial measurement unit, sonar altimeter, radar altimeter, and a 3-axis magnetometer. One or two flight processors can be utilized.
In developing an aircraft simulation, a number of aircraft dynamic models are available with a range of fidelity. However, many applications of simulation also require a model of the flight control or of the pilot to ...

This paper describes the development and validation of the flight simulation model used in the flight simulators of the Joint Primary Air Training System. This model extends to the full maneuvering envelope of the aerobatic T-6A primary training aircraft, and includes the aircraft's aerodynamics, propulsion and flight control systems, and mass properties. Model requirements and validation tolerances are discussed, as well as the unconventional procurement process employed and certain differences in approach between civilian and military cultures which were successfully bridged. Data sources including wind tunnel, air vehicle flight testing and simulation-specific flight tests are described, as is the model's formulation and the desktop simulation and data manipulation tools that contributed to the efficiency of the effort and to the model's fidelity. Finally, the model validation process is detailed, and the test and evaluation phase summarized.
Modern software and hardware solutions available for engineering flight simulation are divided in commonly distributed desktop data and aircraft visualization and high fidelity image generators for pilot-inthe- loop s...
