To compliment this simulation, a top level design of a real time executive kernel has been developed to portray the basic techniques used when designing a real time executive kernel. Investigations into several types of redundancy management algorithms have revealed the differences in the real time requirements for these algorithms in the context of an advanced flight control system, and several of these algorithms have been incorporated into the simulator. The design process of the executive kernel and the redundancy management algorithms offer a basic understanding of how a real time system would be developed and designed. The use of the fault tolerant flight control simulator tool that has been developed allows an investigation, analysis, and trouble shooting of fault tolerant, real time system software architectures to be performed prior to the flight control architecture being formally defined. With the use of this FTFCS tool and the discussed design techniques, the non recurring costs and the actual design time of a flight control computer system could potentially be reduced. Future enhancements and efforts on this topic might include adding to the simulator the capability for processing user supplied scheduling techniques and redundancy management algorithms. This would make the simulation more generic in nature and would enhance its versatility to a greater variety of applications. Other enhancements might include modifying the graphical interface to include a model of a head up display or a three dimensional graphical representation of an aircraft which would mimic the aircraft's dynamic motion under specific pilot input commands.","PeriodicalId":171918,"journal":{"name":"Proceedings of the IEEE 1995 National Aerospace and Electronics Conference.

Our area of concern was the human to machine interface, more specifically, which manual controller or input device should be used for the specified tasks in this architecture. We mailed a survey to 68 companies in order to compile a list of possible input devices that the telerobotics architecture could use. Thirty two companies responded giving us enough data to generate a list that described the physical traits of the input devices. The physical traits were divided into two main categories. The first category, called device category, deals with items such as external power, type of communication interface, and the number of degrees of freedom. The second category called user category, discusses items such as cost, size, weight and dexterity. We then divided the required tasks that the Air Force's generic telerobotics architecture must perform into actions and analyzed them to generate a list of traits required by an input device. Both the task analysis and device listings were combined mathematically to form a performance table which compared the input devices that could perform each individual action.","PeriodicalId":171918,"journal":{"name":"Proceedings of the IEEE 1995 National Aerospace and Electronics Conference.

Performance was evaluated with the current linear force/velocity function and an alternative sigmoidal function designed to elicit improved performance. One experiment utilized a radar update task requiring only fine positioning movements of the cursor. The second experiment consisted of a semi-operational targeting task in which both gross and fine positioning movements of the cursor were required. In addition, the effects of ambiguity of the target pixel and variability in cursor system processing delay were examined. In both experiments, the sigmoidal gain function elicited lower designation time and fewer overshoots than the linear function. Although accuracy of the final designation was not affected by gain function in either experiment, designation error was found to be less than one pixel when the target pixel was highlighted. Variability in the length of the cursor processing delay did not significantly impact designation error, designation time, or the number of overshoots. Subjectively, crew members unanimously preferred the sigmoidal function for performing aimpoint designation.","PeriodicalId":171918,"journal":{"name":"Proceedings of the IEEE 1995 National Aerospace and Electronics Conference.

In this system, the computer controlled plane flies using the control laws under study while a virtual hand (controlled by a glove device) represents the target which the computer plane tries to fly to. In this way, the glove can be used to input evasive maneuvers while the computer controlled plane is observed to determine responsiveness and integrity. The computing platform used for this system is a 33 MHz, 80486 based personal computer. The glove input device is the Mattel PowerGlove modified for use on the computer. Stereo vision is provided by a pair of Sega shuttering lenses. The system software was developed using Borland's Turbo C++ compiler and is written entirely in the language \"C\". The graphics and interfacing software is provided by a public domain rendering library entitled \"Rend386\". The specific results obtained after developing the system include: the creation of a flexible, modular system which can be expanded as the need arises, a unique interface which provides an intuitive means to evaluate complicated control systems, the entire system is simple in design and is easily implemented using \"off the shelf\" virtual reality components (gloves, glasses, etc.).","PeriodicalId":171918,"journal":{"name":"Proceedings of the IEEE 1995 National Aerospace and Electronics Conference.
