This paper presents a review of the Flight Dynamics Head-Up Guidance System, a status on the progress towards certification of category IIIB approaches, take-off strategies, and accurate economic justification models. Head-up guidance is back in the spotlight. For various reasons, enhanced vision has a limited near-future. Yet airlines still want to operate in low visibility. The proven way is with head-up guidance. The status of current users and new users of head-up guidance systems are discussed. New uses for head-up guidance and fusion with other new sensors are also discussed.<>

The advent and growing popularity of object-oriented software design and development technologies present the user interface designer with new tools and new challenges. The use of Object-Oriented Technology (GOT) enhances the user interface designer's ability to design graphical user interfaces while dramatically changing the role of the designer as a member of the software development team. Object-Oriented Technology attempts to map real-world problem domains into software both at the system and the user interface level. The user interface designer, as user advocate and problem domain analyst, is faced with the task of developing a user interface that can be extended to incorporate new functionality, without major interface redesign while taking on an expanded role as a member of the development team This paper discusses a software application design methodology that incorporates the analysis techniques of OOT into a method for collecting, formalizing, and embedding user requirements into software design.<>

This paper provides a user-based orientation intended to assist in understanding, organizing and designing future, responsive information nets using predictive data management techniques. A fundamental premise is that it is the quality of data as it accurately represents dynamic events and provides action recommendations, not merely the quantity of information or its accuracy and timeliness, that forms the basis of a satisfactory net. The paper argues that predictive, electronically-based decision-assisting systems, using hybrid, fuzzy logic to overcome human limitations resulting from selective perception and risk minimization, may be more valuable to the management of battlefield information (could provide more powerful, quality data, or information) than currently thought. Such systems should be considered not only to support cognitive decision-aiding in future aircraft crew stations but also perhaps to autonomously make and implement the results of such decisions for players at all levels of the battlefield.<>

A production program is underway for an Active Matrix Liquid Crystal Display (AMLCD) for the National Aeronautics and Space Administration (NASA) Space Shuttle glass cockpit upgrade. A "smart" display architecture is used with a powerful Reduced Instruction Set Computer (RISC) processing element and custom graphics accelerator that can render two- and three-dimensional (2-D and 3-D), fully anti-aliased graphical images at 30 Hz update rates. In addition, the Multifunction Display Unit (MDU) can display external NTSC/RS-170 video to crew members, or output an NTSC signal for repeater monitor requirements. The unit is a very compact design-minimizing volume, weight, and power. Advanced AMLCD technology delivers exceptional brightness, gray-scale performance, off-axis viewing, and dynamic image response across the full 6.71/spl times/6.71 in. active display area. High resolution is achieved with 1152/spl times/1152 color dots and 28 shades of gray per primary color. Exceptional imaging quality, throughput, graphics generation, and reliability all combine to produce a display package that greatly enhances flight-deck performance.<>

The Air Force is considering several token passing local area networks (LANs) for use on high performance aircraft. This paper compares two of the fiber optic LANs considered: the Society of Automotive Engineers (SAE) linear token passing bus (LTPB) and the American National Standards Institute (ANSI) fiber distributed data interface (FDDI). ARINC Research Corporation compared these two LANs in terms of their station and network topologies, media access control, capacity allocation, and latency. The SAE LTPB is a LAN designed for military avionics, while the ANSI FDDI was not originally designed for avionics. ARINC Characteristic 636 (1992) expanded the ANSI FDDI into a standard for commercial aircraft avionics which is discussed as an avionics application of the FDDI.<>

In this paper an on-board computer system for the first Korean satellite, KITSAT is presented. The design technologies for large commercial satellites cannot be directly used for the microsatellite due to the compactness. The design drivers and decisions made in the development of the KITSAT on-board computer system are described to fulfil the microsatellite design constraints. The features of on-board computer hardware and operating system are presented. The in-orbit performance of a mission control computer (MCC) is also discussed with the memory subsystem error log and the attitude control subsystem results.<>

The advent of the Global Navigation Satellite System (GNSS) is having a profound impact on surveying, mapping, and navigation. Nowhere is this more evident than in civil aviation. In addition to the capability for cost effective precise positioning and navigation there is now the possibility to conceive systems based on this technology that for the first time can provide automatic dependent surveillance (ADS), cockpit display of traffic information (CDTI), and collision avoidance (CA) functions. To accomplish these functions a complementary data link is needed. Preferably this data link can enable the needed functionality without the need for the creation of an extensive ground infrastructure on behalf of the government and yet provide aircraft operators with a system with which they voluntarily desire to equip without the need for mandatory and artificially expensive equipage. This paper addresses a concept to accomplish these desired aviation functions which will be referred to here as the GNSS augmentation data link (GADL).<>

To help alleviate reliability and maintainability problems with optical networks in weapon systems such as the Air Force F-22 tactical fighter and the Army RAH-66 attack helicopter, a reliable, blind-mate optical connector using multi-mode fiber was developed for the Air Force by AT&T. In 1993 the final prototype was developed and tested, successfully passing the severe military test environment. It was then transitioned to the F-22 program. This connector is fine for most digital applications. The next technology step will be to develop a single-mode version of this reliable optical connector-the SROC-for digital and analog applications. There are many benefits of developing this connector so that it can be used in optical systems with laser transceivers. Higher power margins can be achieved. Greater bandwidth than that of LED systems will be attained. This paper will cover the design, development, and preliminary testing of a SROC. This will include risk issues of propagation modeling, alignment, fiber eccentricity, and polarization. A discussion of the multi-mode ROC and the planned test environment will also be addressed.<>

The Maintenance Access Terminal (MAT) and Side Display (SD) are powerful processing resources with high resolution liquid crystal displays, networked to other airplane systems with a fiber optic communication interface. They provide a common resource for night crew and maintenance personnel to access information from other airplane systems, such as initially the On-Board Maintenance System (OMS). The MAT/SD are designed as an open architecture, avionics ruggedized, 486 diskless workstations. They are designed for a single user, with sufficient processing power and memory to run third party application software. The MAT consists of a display/processor unit, which is identical to the Side Display, a cursor control device (trackball) and keyboard for user interface, a 3.5" floppy disk drive, and an optional hard disk drive. Each of these items are line replaceable modules that install into a MAT cabinet. This paper overviews the system development, design, and functionality of the 777 MAT/SD.<>
