(7) ILS Course (Magenta)
When the pilot pushes the LS pushbutton switch on the EFIS control panel, and if an ILS
station has been selected, the display shows an ILS course symbol.
(8) ILS Marker Beacons
The screen shows these as waypoints (diamonds).
When the aircraft overflies a marker beacon, the corresponding symbol flashes :
Blue for the outer marker.
Amber for the middle marker.
White for the inner marker.
(9) Cross Track Error
This is the aircraft's lateral deviation from the active leg of the flight plan (related to the great
circle route). It is indicated in nautical miles (NM), with the letter R (right) or L (left), according to
the position of the aircraft with respect to the flight plan.
(10) Track line
This line appears in green only in the ROSE NAV or ARC mode when HDG or TRK has been
selected on the FCU.

(11) Procedure turns and holding patterns
These appear only when they are part of the flight plan. For the 160 and 320 nm range scales,
each one is represented by a white arrow that originates at the associated fix and indicates the
direction of the turn.
For shorter range scales and if the procedure turn or the holding pattern is in the next or the
active leg, the display shows the full circuit or pattern.

ROSE NAV MODE/ARC MODE
Applicable to:
MSN,
ROSE NAV and ARC modes give the pilot the same information, but ARC mode limits it to the
forward 90 ° sector.
(1) Range Marks and Values
The values displayed on the ND are :
In ROSE NAV mode 1/4 of the selected range for the inner circle.
1/2 of the selected range for the heading scale circle.

In ARC mode 1/4 of the selected range for the first inner arc.
1/2 of the selected range for the second inner arc.
3/4 of the selected range for the third inner arc.
(2) Flight Plan
The crew can use the MCDU to select various types of flight plan :
• The active flight plan (the flight plan the aircraft is actually following when the NAV mode is
engaged) is represented by a continuous green line. The ND shows only the part of the flight
plan that is ahead of the aircraft, as well as the waypoints that are still to be overflown and
the waypoint from which the aircraft is coming.
The ND does not show a SID or a STAR, except for the last waypoint of the SID and the first
waypoint of the STAR, when the selected range is 160 or 320 nm.
If the primary flight plan is not active, it is represented by a dotted green line.
• A continuous blue line portrays the missed approach procedure, and a dashed blue line
portrays the flight plan to the alternate.
The missed approach and the alternate flight plan are displayed when :
In ARC or ROSE NAV mode, a missed approach waypoint ‐ or an alternate flight plan
waypoint is displayed on the onside MCDU.
‐ In PLAN mode a missed approach or alternate waypoint is displayed in the 2L field of the
onside MCDU.
• The secondary flight plan is represented by a continuous white line. The ND continues to
display the active flight plan.
• Temporary flight plan
The revised portion of the flight plan is represented by a dotted yellow line.
• Flight plan capture
When the aircraft is off the primary flight plan and is flying toward it in HDG mode with the
NAV mode armed, the ND shows the new active flight plan as a continuous green line if the
FMGC has computed the intercept path.
The part of the flight plan before the interception point shows as a dotted green line.

(3) Waypoint
The ND can display various kinds of waypoints :
Flight plan waypoints
The ND displays these as green diamonds (white, for TO waypoints). When the flight crew
selects the WPT option on his EFIS control panel, all waypoints other than flight plan waypoints
are displayed in magenta.
Pseudo waypoint
Point of the flight path where the aircraft is predicted to reach a selected altitude or speed.
