专利汇可以提供Flight management display专利检索,专利查询,专利分析的服务。并且Pilot-oriented information is displayed on the screen of a cathode ray tube by electronically generated symbols superimposed on a simulated or real-world picture. The symbology uses as one datum a fixed airplane symbol and locates therefrom the airplane''s degree of pitch, degree of roll, and the horizon. In addition, symbols are provided to indicate the relative position of the airplane with respect to ILS localizer and glide slope signals, pitch and roll commands obtained from an on-board flight director computer, a desired pitch reference, and actual as well as potential flight path angle. Deviation from a preset airspeed and radio or radar altitude are also shown. In all cases, the symbols are constructed by symbol generators from one or more basis rectangles, whose width is determined by a pulse of appropriate length during the CRT''s horizontal scanning period, and whose height is determined by a similar pulse during the vertical scanning period. The location of each rectangle is determined by the delay between the start of the vertical or horizontal scanning period, and the start of the vertical or horizontal pulse. Modifications are described for generating rotating symbols. The outputs of the symbol generators are combined as a priority circuit and converted into a composite video signal by a video mixer.,下面是Flight management display专利的具体信息内容。
