The EFIS-86E electronic flight instrument systems combine Electronic Attitude Director Indicator/Electronic Horizontal Situation Indicators (EADI/EHSI) with a center panel multifunction display (MFD) to provide a fully integrated flight deck display system. The EADI expands the horizons of a conventional five-inch electromechanical instruments with a 50 percent larger earth/sky representation for terminal and en route formats. The EHSI combines multiple display formats with weather radar and built-in NAV source selection for simplified coordination of all navigation and weather avoidance tasks. The MFD augments the EADI/EHSI displays by providing the pilot and copilot with additional navigation, weather avoidance, data management and reversionary functions.

The EFIS-86E is comprised of a family of components that can be configured to meet various flight deck display applications. The system components are:

The EFIS-86E can be configured in two-, three-, four- or five-tube systems, depending on the flight deck application. (See tables for system totals and equipment complement)

The EFD-86 and MFD-85( ) contain a CRT, deflection yoke, video and deflection amplifiers, and high voltage power supply. The CRT is a high-resolution color tube. The CRT has an in-line gun with shadow mask that uses a black matrix surrounding pigmented phosphor dot trios; this provides high contrast along with high resolution. A custom design, multiband pass optical filter is used to provide enhanced contrast. Both stroke and raster scanning techniques are used to provide large area color background for weather and distinct alphanumerics and symbols with high brightness. Mode select and display control functions are located on the display bezel for the MFD-85( ).
