MFD OR NAVIGATIONAL DISPLAY MODES A320 airbus

ND modes are selected using selector knob on EFIS control panel. Another selector knob changes display range from 10 to 320 nm.

ROSE ILS and ROSE VOR modes are mainly used during ILS and VOR approaches they display selected course needle, course deviation indicator, along with all other common information. Other three modes display active flight plan route. ROSE NAV and ARC modes show a map with overlaid route display, ROSE NAV mode showing full 360 degrees around aircraft, and ARC showing forward sector. PLAN mode allows reviewing entered route by stepping and centered through all way points on the route.

 1. Heading

A yellow index marks presents aircraft heading on the rotating heading rose.

2. Groundtrack

Green diamond mark displays current aircraft ground track, which is different from heading in crossing conditions.

3. Selected Heading

Blue triangle shows heading selected on FCU. It is removed when flying in managed lateral (NAV) mode. In ND ARC mode, if selected heading is outside visible arc of heading rose, it is numerically displayed at the heading arc side closest to the selected heading.

4. GS/TAS

Digital indication of current ground speed and true speed.

5. Wind

It gives digital indication of current direction and speed. If wind is present; a green arrow shows wind direction relative to aircraft heading.

6. Bearing Pointer

Needles point to tuned navaid stations appear only when a navaid is selected for display on EFIS control panel. Bearing pointers represent bearing to stations received by radios selected for display on EFIS control panel.

7. Selected Navaids

Information on tuned navaids, selected on EFIS control panel include selected receiver, navaid identifier, and DME distance if available .A letter “M” is added after navaid name if navaid is manually tuned on MCDU Radio navigation page. A letter “R” is added if a frequency is manually tuned on radio management panel. No letters are added when navaid is auto tuned by FMS. Arrow symbols show which bearing pointer on the rose display represents this navaid.

8. Range Marks

Located at range circles and define corresponding circle range from the aircraft symbol. In ND ARC mode, the outer circle represents the range selected on EFIS control panel in all other modes, the outer circle has half the range selected on EFIS control panel.
