The EFD-84 is a panel mounted 4 inch CRT display. The EFD-84displays information supplied by a DPU-84 Display Processor Unit or MPU-84Multifunction Processor Unit. The EFD-84 can function as an EADI and EHSI, ora radar indicator. When the EFD-84 is used as an Electronic Attitude DirectorIndicator (EADI) it presents a multicolor CRT display of aircraft pitch androll attitude, autopilot mode annunciations, vertical deviation, lateraldeviation, autopilot engage status, attitude/heading comparator warnings anddecision height set. Other displays are displayed as a function of pilotselection or operation mode such as attitude source, radio altitude,excessive ILS deviation and comparator warning, fast/slow deviation orangle-of-attack deviation and marker beacon. Interconnect strapping enablesmore display options such as cross pointer or command bars, speed deviationdisplay inhibit, enable or inhibit rising runway and enable or inhibitcomposite format in reversion. Electrical connections to the EFD-84 are madethrough two 25-pin keyed Cannon D-type connectors. The connectors arephysically mounted to circuit card assemblies inside the unit and extend outthrough the chassis and cover at the rear of the unit. Threaded screw holesare provided in the bezel assembly for mounting an inclinometer when theEFD-84 is used as an EADI. When the EFD-84 is used as EHSI a cover plate isinstalled on the bezel assembly over the area that would otherwise be occupiedby the inclinometer.

Each EFD contains a CRT,deflection yoke, video and deflection amplifiers and high-voltage powersupply. The CRT is a Collins specified custom high resolution color tube. Thetube has an in-line gun with shadow mask, using a black matrix surroundingpigmented phosphor dot trios, providing high resolution and contrast ratio. Acustom design multi band pass optical filter is used to enhance contrast.Both stroke and raster scanning techniques are multiplexed to provide largearea color background and sharp alphanumerics and symbols with greater thannormal illumination. Two units stacked use the same panel space as theEFIS-84 electromechanical units. All EFD's are identicalinternally.

The EFD-84 also provides ahigh temperature warning output that can drive an external installer-suppliedannunciator .This annunciator will illuminate if the internal temperature ofthe EFD-84 reaches +95 °C (+203 °F) in still air.The EFD-84 requires the airbehind the cockpit panel to be circulated to ensure optimal performance.These units are capable of operation for a short time at the elevatedoperating temperatures specified in the environmental section of thisspecification without cooling air. However, operation at these levels is notconsidered normal. The EFD-84 is enclosed in a housing which has cooling airholes on the top, bottom, both sides, and rear surfaces. The EFD-84 has anintegral cooling fan mounted on the rear of the unit. The unit mountingflange is attached to the outer surface of the instrumentpanel.
