  • Electromagnetic vulnerability testing of aircraft using mode-stirred techniques

    Publication Year: 1996, Page(s):351 - 357

    Electromagnetic vulnerability (EMV) testing is typically performed on aircraft using a standard method where the aircraft is directly radiated by an antenna, with no mode-stirring. Since a standing wave pattern will cause peaks and nulls in the field inside the aircraft, many antenna aspect angles should be used to assure that all equipment on board the aircraft is exposed to the appropriate field...

    United Airlines began using Flight Management Systems (FMS) in 1982. The FMS-equipped aircraft operated initially in the domestic environment. Eventually, FMS-equipped aircraft operated on very long segments, such as Los Angeles to Hong Kong, which often required operation of the aircraft at multiple limits such as maximum takeoff weight, maximum fuel capacity, and/or specified fuel reserves. Thes... View full abstract»

    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 wide... View full abstract»

    This study examines a pilot's understanding of the avionics' behavior while flying. Under most conditions, pilots are able to successfully understand the avionics during flight. There are times, however, when the pilot may not be totally aware of what the avionics are doing, why an action is being performed, and what the automation will do next. Explanations of these conditions that lead to aviati... View full abstract»

    The current airborne collision avoidance system provides pilots with approximate information on the relative location of nearby traffic, and with recommended escape maneuvers in the vertical plane. It relies on range measurements, and suffers from high false alarm rate. This paper studies a new collision avoidance system, which is based on periodic broadcasts of aircraft position as derived by an ... View full abstract»
