Synthetic vision flight tests for curved approach and landing

A computer generated synthetic vision system was developed for improving poor visibility guidance in flight close to the ground. The system comprises a 3-dimensional outside world image, integrated guidance information including novel features (perspective flight path display) and high precision navigation as basic elements. A comprehensive flight test program consisting of five test series was set up for testing for a wide range of guidance applications of synthetic vision, including approach and landing. Demanding control tasks were specified and investigated. The results of the flight tests show that the synthetic vision system enabled the pilot to precisely control the aircraft and to accurately follow the specified trajectories. All guidance performance goals were achieved
