This project involved development of a helicopter flight simulator and its application to study instrumented flight rules (IFR) landing approaches. The helicopter simulator was implemented on the University of Toronto Institute for Aerospace Studies (UTIAS) Flight Research Simulator. It employed all the major subsystems of that facility including the motion systems, visual display system, sound system, and computer system. In addition, the flight controls and seat of a Bell 205 helicopter were installed and interfaced with the flight computer. An electronic flight instrumentation system (EFIS) was developed to act as the pilot helicopter interface. A side arm controller was also included in the simulation. The helicopter flight equations were based on an ARMCOP software package. The system was tuned with the help of an experienced Bell 205 test pilot. The simulated flight test project was directed towards establishing the ability of the simulator to duplicate handling qualities results achieved in actual flight. The task selected was that of decelerating IFR approaches using flight control systems and a three cue flight director. A group of 6 evaluation pilots repeated flying tasks previously completed in an actual Bell 205. Good agreement between the simulator and flight test data was achieved except for one configuration. This configuration was found to be easier to fly in the simulator. The cause of this was felt to be incorrect simulation of the corresponding flight control system.
