Image Quest has developed a flight quality, high resolution, full color, high luminance, wide temperature range display module based on Active Matrix LCD (AMLCD) technology that has excellent contrast in full sunlight. The display is well suited for use in electronic replacements for the electro-mechanical 5ATI (five inch case size) flight indicators and offers greatly improved display format flexibility, operating reliability and display contrast in all ambient lighting conditions as well as attractive cost advantages. The display module is very close to meeting the predetermined design goals.

Safety levels are a vital concern as new technologies and procedures are introduced into the National Airspace System. Despite a wealth of information from flight operations and testing programs, there is no accepted method to quantify the relationship between safety levels and aircraft separation standards in the terminal area. This paper presents a modeling approach to quantify the risk associated with reducing aircraft separation. The model is used to assess the overall level of safety associated with reducing separation standards and the introduction of new technology and procedures, as envisaged under the free flight concept.

This paper describes a method that has been used to install and calibrate angle-of-attack (AOA) vane sensors on out-of-production jet transport aircraft that have never been equipped with such sensors. The calibration process is accomplished without using a boom-mounted AOA sensor which is commonly used during new aircraft certification flight testing. Instead, a commercial AOA vane sensor is installed on the fuselage and then flight test data is collected under conditions that allow measurements of actual AOA using accelerometers and the aircraft attitude gyros. The flight data is analyzed to extract the actual AOA and generate the transformation that maps the output from the AOA vane sensor to actual AOA.

Commercial products and practices offer the potential of reduced costs, lower risk and faster technology insertion opportunities. However, in the domain of high performance aircraft avionics, the potential for change is likely to be limited without an in-depth comprehension of the military environment, its specifications/requirements, and the capability of commercial products to satisfy them. Hughes developed a synthetic aperture radar (SAR) using commercial components and practices based on designs initially made for the military market but this radar was not targeted for use in the U.S. Military. The first sale of this radar however, was made to the U.S. Military and they have now embraced it for their use. This paper describes how traditional military requirements were satisfied with extensive use of commercial technologies and practices.

The Massachusetts Institute of Technology, Boston University and Draper Laboratory have cooperated to develop an autonomous aerial vehicle that won the 1996 International Aerial Robotics Competition. This paper describes the approach, system architecture and subsystem designs for the entry. This entry represents a combination of many technology areas: navigation, guidance, control, vision processing, human factors, packaging, power, real-time software, and many others. The aerial vehicle, an autonomous helicopter, performs navigation and control functions using multiple sensors: differential GPS, inertial measurement unit, sonar altimeter, and a flux compass. The aerial transmits video imagery to the ground. A ground based vision processor converts the image data into target position and classification estimates. The system was designed, built, and flown in less than one year and has provided many lessons about autonomous vehicle systems, several of which are discussed.

The mission of the joint strike fighter (JSF) program is to facilitate evolution of fully developed and validated requirements, proven concepts, and mature demonstrated technologies to support successful development and production of next-generation strike weapon systems for the U.S. Air Force (USAF), Navy (USN), Marine Corps (USMC), and US allies. Commensurate with its mission, the JSF Program endeavors to reduce the cost of developing strike fighter software by maturing and demonstrating software technology, standards, and processes. Several critical technology areas have been identified. The areas are programming languages, secure real-time operating systems, software engineering environments, and software architectures. In each of these areas, technologies have been identified to accomplish the overall goal of affordable software for next-generation strike fighter avionics. During FY95, the JSF program sponsored demonstrations as part of the JSF Risk Reduction Studies/Demonstrations (RRSD) phase. Throughout this phase, emphasis has been placed on leveraging accomplishments made from several sources including the Defense Advanced Research Projects Agency (DARPA), and USAF and USN scientific and technical efforts. The corresponding technology demonstrations featured Ada 95, Portable Operating System Interface (POSIX) standards, software fault-tolerance, and several technologies demonstrated under DARPA-sponsored Domain Specific Software Architectures (DSSA) program. This paper describes the accomplishments made to date by the JSF program, and includes future plans.

Future system designs combining modern programming language code with existing avionics software are qualitatively analyzed. The evaluation criteria are development cost and run time efficiency. Based on these criteria, strategies using messages to coordinate applications residing in separate address spaces are preferred.

An advanced technology X- and Ka-band (8 and 32 GHz) Tiny Transmitter is being developed for the New Millennium program and is described in this paper. The Tiny Transmitter is the first development phase of the Tiny Transponder which will incorporate recent advances in miniaturization and flexibility of radio systems by utilizing digital radio techniques. These techniques incorporate digital technology and algorithms to perform many functions which have traditionally been performed by analog circuits and allow the complexity of the RF portion of the radio to be minimized. The Tiny Transponder will be able to meet the needs of many deep space missions presently being planned for launch after the year 2000.

Although there are many commonalties between fixed-wing and rotary-wing aircraft, both in terms of their performance and the missions they fly, their extensive differences demand that we recognize the training requirements that are unique to rotary-wing vehicles. In addition, the rotary-wing industry is made up of many widely distributed small operators whose training needs and logistics vary widely from those of the well-ordered, capital intensive, air carriers. The relative absence of large operators in the rotary-wing industry is a source of challenge to training-equipment manufactures and to the federal agencies responsible for supporting and regulating the development of aviation. In anticipation of growth in the rotary-wing industry, the Federal Aviation Administration (FAA) has proposed new rules, Part 142 Title 14 CFR, which will authorize and regulate certified training centers. The objectives of the new rules are to increase simulator use, eliminate the need for simulator exceptions, standardize training, and standardize the FAA's oversight of training.

The Free Flight Evaluation System (FFES) is part of a larger ongoing effort at CAASD (MITRE Corporation's Center for Advanced Aviation System Development) to investigate Free Flight concepts and capabilities. This project includes studies designed to answer key questions associated with the changing roles envisioned for system operators and users: pilots, controllers, flight planners, and traffic managers. In conducting this research program, CAASD's main strength lies in the conceptual framework and collaborative approach it brings to ATM system problems and in its unique institutional expertise in dealing with complex problems posed for research in operational environments. The CAASD is tying together various facilities and FAA, industry, and academic partners to research Free Flight issues.
