Flight simulation has always been an application which needed to be distributed in order to be computable at all. Although examples of single-processor flight simulators exist [2] they are typically simulators of low fidelity, often games. True flight simulation has extremely high fidelity demands: the virtual environment which the simulator creates must be as life-like as possible in order to train the aircrew as effectively as possible. Even in simulators created 30 years ago, distribution was utilized:

Linear computing operations, such as summation, integration and sign changing, are performed by d.c. operational amplifiers, consisting of high gain drift correct amplifiers with appropriate resistive or capacitive feedback networks. There are 150 such operational amplifiers . . . The non-linear part of the computing equipment consists of servo-multipliers, electronic time-division multipliers, and diode function generators. In addition, forty-eight high gain amplifiers are available for special computing circuits which may be built up for each simulation . . . The individual computing amplifiers, potentiometers, multipliers, etc. are connected together to form the overall computation network by means of a central patching panel, having over 2300 terminations.

Although the effects produced by such a simulator are primitive by today’s standards, many of the principles behind the system’s architecture have not changed. A single computer typically cannot provide the functionality and/or the raw computation power to serve a flight simulator, or if it could, it would be horrendously expensive. This situation is not likely to change: as computer power increases, so do our demands and so does the complexity of the air vehicles being simulated. Thus, a number of computers were “patched” together through a patch panel 30 years ago in order to create a flight simulator; today, they would typically be connected through a fibre-optic network.

Abstract:

This paper explains how flight simulation has made a major contribution to flight safety over the last thirty years to become critical to the operation of civil airlines and military organisations. It not only provides effective training, but for many flight training organisations has reduced the cost of flight training significantly. The paper outlines the increasing role of flight simulation covering flight training and research and development of aircraft and systems. The contribution of the flight simulation industry to the UK economy, in terms of both employment and revenue, is highlighted. The paper focuses on advances in the underpinning technologies of flight simulation, including mathematical modelling, real-time computation, motion actuation, visual image generation systems and projection systems. The paper also summarises the broadening roles of flight simulation; from part-task trainers to zero flight-time training in civil aviation; in military aviation, extending to combat domes and mission rehearsal; in defence procurement, where synthetic environments are used widely in evaluation studies prior to major project commitments; in aircraft development, providing powerful design tools to enable system designers to evaluate prototype systems. As a result of the acceptance of flight simulation in flight training, the use of simulators has been standardised throughout the world, with formal programmes of simulator qualification. These regulations, drawn up with the help of the RAeS Flight Simulation Group, ensure consistency for operators, regulators and manufacturers; the status of these regulations is outlined. The paper concludes by reviewing the lessons learnt by the flight simulation industry over the last thirty years and summaries the potential areas of growth, which will lead to simulation becoming widespread throughout many industries, in addition to the aerospace industry.
