Depending on the aircraft avionics configuration the FMS information can be made readily available to both Pilot and Copilot primary display instruments. Aircraft equipped with EFIS (Electronic Flight Instrument System) FMS information can be overlaid and or displayed independently of other flight information. MFD - Multi Function Display The MFD (Multi Function Display) is a typical instrument display used to present flight plan and path information from the FMS to the aircrew. User defined waypoints and other navigational aids may be presented on the MFD. Usually a course line is displayed to represent the intended flight path and is normally drawn from a aircraft symbol located near the bottom of the display. Most EFIS and MFD displays allow information to be overlaid one another such as RADAR information could be overlaid the intended flight path. HSI - Horizontal Situation Indicator The HSI is capable of showing FMS course deviation information. Distance information to the waypoint is usually presented in a numerical readout on the HSI. Most EHSI (Electronic Horizontal Situation Indicators) provide different format layouts such "Arc" or "Full" HSI presentations. Like the MFD the EHSI is capable of overlaying other flight information. Flight Director / Autopilot FMS navigational information is made available to the flight director. The flight director interprets the FMS navigation information and computes neccesary steering command outputs that are displayed on the ADI. When FMS NAV is selected via the mode selector, flight guidance information is displayed on the ADI (Attitude Director Indicator). "V-Bars" are used to show flight guidance and direct the aircrew, of the flight path, on the ADI. Most flight plans are coupled to the autopilot which receives steering commands from the flight director and moves the flight controls to keep the aircraft on course. Annunciators / Crew Alerting Individual / standalone annunciators are normally used to alert the aircrew of FMS modes, failures and warnings. Sometimes the same alerts are incorporated into EFIS displays. Incorporating the annunciators into EFIS can dramatically clean up an instrument panel.
