A Program for Determining Flight Simulator Field of View Requirements

Year: 1978

Authors: R. Yeend, D. Carico

Abstract: This paper discusses a test approach for determining the optimum field of view of a flight simulator visual system as a function of aircraft mission. The program is intended to provide the information needed to decide which portions of the aircraft's total field of view should be simulated and which can be disregarded. The approach consists of three phases: drawing board evaluation, aircraft ground testing, and flight testing. The procedure is described using the CH-46 helicopter as an illustrative example but it is applicable directly to any aircraft, fixed or rotary wing. Pilot qualitative ratings are obtained for each simulated visual configuration during specified flight maneuvers. Results from the CH-46 program indicated that a pilot/copilot oriented visual system limited the training potential for both crewmembers. The optimum configuration for the CH-46E operational flight trainer was a pilot oriented visual system.

A New Approach for Electronic Warfare (EW) Aircrew Trainers

Year: 1978

Authors: Burton Graves, Daniel Marchegiani

Abstract: This paper discusses the ever-increasing role of EW training as an outgrowth of the expanding emphasis on EW in our national defense program. It discusses the basic requirements of EW aircrew trainers and the solutions available. One solution is the hardware stimulation approach, employing racks of pulse and scan generators to provide RF or video inputs into operational EW equipment. The other solution is the software simulation approach, modeling the emitter environment and EW equipment in a general-purpose computer and providing outputs to drive the EW equipment displays and control panels. The software approach has significant advantages in hardware cost and complexity, instructor/operator interface, reliability, maintainability, and ease of update and modification. However, fears of modeling the highly sophisticated EW equipment and environments have kept this approach from being used. This paper demonstrates that the software approach can be successfully employed. A discussion of an RWR training device recently developed by ATI and using the software approach is contained in this paper. Finally, a discussion is presented on the application of the software approach to new and future EW systems.

User Acceptance in an Automated Speech Technology Based Training System

Year: 1978

Authors: Mary Hicklin, Gail Slemon

Abstract: There are many challenging problems facing the system designer in the application of the automated speech technologies to simulation. We have attempted to show that effective strategies can be designed to employ these technologies in a training environment. These strategies include techniques for augmenting shortcomings both in the state of the art and in user performance to produce a system which can respond intelligently, be acceptable to the user, and can provide excellent training. These concepts will soon be ready for testing, and we look forward to a successful field evaluation.

Myoelectric Feedback Control of Acceleration Induced Visual Scene Dimming in Aircraft Training Simulators

Year: 1978

Authors: D. Rogers, D. Quam

Abstract:

Visual dimming experienced during aircraft maneuvering accelerations is an important information source for the simulator pilot. A method for integration of the man with the simulator is demonstrated using computer-based physiologic models and readily measured electromyographic signals arising from the straining maneuver. This technique forces active participation and energy expenditure by the simulator pilot similar to the requirements of the aircraft pilot undergoing acceleration.

Simulation models are developed which relate the effects of the G suit, straining techniques and the cardiovacsular response system to a single protection variable (PV). The PV signal drives a predictive visual field model derived from analysis of the retinal circulation in the eye. Allowances are made for subject variation and cockpit seating configurations.

The model produces accurate predictions of short-term Gz tolerance in its present form and with slight modifications can be adapted to include energetic costs for long-term accelerations.
