Introduction

The flight simulator was designed and built as part of a student project. The mock-up is modelled on the aircraft type of a Cessna 172S, whereby attention was paid to maintaining the real dimensions and to arranging the instruments as realistically as possible. The flight simulator has since been used in several laboratory studies to investigate the human influence on the variation of the landing gear load.

Technology

Three monitors are installed to simulate the view, which together allow a viewing angle of 120°. A head-tracking system is also used to extend the visibility, which changes the angle of view in relation to the pilot's line of sight. Thus, especially under visual flight conditions, orientation can be maintained.

The mock-up is based on the aircraft type of a Cessna 172S. The main control elements, such as the yoke and the pedals, were implemented as real replicas. The digital realization of the instrument display by means of a display allows the simulation of other aircraft types in addition to the Cessna or adjustments to the available instruments. Furthermore, the mock-up was extended by a simulated GPS system to provide a familiar flight environment.

A powerful computer is used to control the hardware and software components.

Application

The flight simulator software used is Flight Simulator X (FS X) from Microsoft. In addition to some extensions for controlling the digital instruments, a black box software is installed, which allows a parallel recording of 255 flight parameters with a sampling rate of 18Hz. The recording function integrated in FS X also allows multiple evaluations as well as the subsequent replay of flights and flight courses.

A new aircraft model for the Cessna 172 as well as extended scenario packages for environment display were integrated to increase the degree of realism.
