    The data acquisition phase of a program intended to provide data for the validation of computational, analytical and experimental techniques for the assessment of electromagnetic effects in commercial transports, for the checkout of instrumentation for following test programs, and for the support of protection engineering of airborne systems has been completed. The initial phase involved on-the-ground electromagnetic measurements. Measurements were made of the fields coupled into the aircraft interior and signals induced in select structures and equipment under controlled illumination by RF fields. A characterization of the ground was also performed to permit ground effects to be included in forthcoming computer modeling exercises. A series of fly-by experiments were conducted in early 1995 in which the NASA B-757 was flown in the vicinity of a Voice of America station (~25 MHz), a fixed transmitter driving a log periodic array (172 MHz), and an ASRF radar at Wallops Island (430 MHz). In this paper, the overall test program is defined with particular attention to the on-the-ground portion. The test rationale, test layout, and samples of the data are described. Samples of some inferences from the data that will be useful in protection engineering and EM effects mitigation will also be presented View full abstract»

    This paper describes an innovative process for re-hosting test program sets from an existing tester for which they were originally prepared to operate on another tester. The process greatly reduces the time and cost usually required for offloading a test program set while retaining most of the original design and interface hardware View full abstract»

  • Systems integration of the 777 airplane information management system (AIMS)

    The systems integration of the 777 Airplane Information Management System (AIMS), both within the AIMS system and with the other systems on the airplane, represented the most complex system integration effort ever undertaken at Honeywell Air Transport Systems Division. The technological innovations in the AIMS design, coupled with an aggressive program schedule were major factors in the AIMS challenge. Honeywell and Boeing had to work closely together to complete the design and development of AIMS in a time frame that supported the 777 Early ETOPS goal. With teams from the two companies working as one unit, redundant activities were eliminated, technical and program problems were identified and solved rapidly, and schedule time was saved by both teams helping with tasks that were traditionally considered to be the other team's job View full abstract»

  • Systems integration, user interface design, and tower air traffic control

    Tower air traffic control is currently performed using several unintegrated systems. While each of these systems supports performing an isolated task, the compilation of tools presents a number of challenges. This paper reports ways in which the Tower Control Computer Complex (TCCC) will support and enhance user management of numerous systems. Areas that will be notably improved include the consistency in the user interface of the air traffic control toolset, the task of manually integrating tools and information, toolset alert management, and toolset organization and administration View full abstract»

  • A phase controlled antenna system for anti-jamming purposes

    A phase controlled antenna system has been constructed for aircraft EW purposes. With only two radiating elements conventionally installed on top of the fuselage, the system is capable of introducing a 30 dB radiation pattern minimum to desired or optimized directions. The system uses computer controlled parallel down conversion technique, which gives the freedom to automatically adjust for any anomalies in the respective individual element patterns, normally caused by the airframe structures. The same computer can be used for active search-and-minimize procedures. Extensive tests have been performed with an F-18 scale model to verify the system performance View full abstract»
