The symbols of the navaids which are tuned, either automatically or manually (VOR-DME, and ILS or ADF when they belong to the SID/STAR procedure) are displayed in cyan color. In addition, each pilot can have on request additional information displayed by pressing the desired pushbutton switch on his EFIS control section:
-ARPT for airports, presented with a star symbol if runway is not specified , and with an orientated runway if runway is specified.
-NDB navigation stations (triangle symbol)
-VOR-D navigation stations (a cross for VORs, or circle plus cross symbol for VOR-DMEs)
-WPT waypoints (lozenge symbol)
-CSTR constraints, which are the constraints at waypoints (altitude, speed, time), and which are provided for the TO and for the NEXT waypoints only.
Level points, speed change points, constrained waypoints are indicated on the flight plan by means of specific symbols: respectively, arrows, small circle, large circle surrounding the waypoint. These symbols are in magenta when associated to a constraint (in altitude or speed). The holding patterns and procedure turns are represented by a half-circle arrow with the higher range values selected, and by the complete circuit drawn at full scale with the lower range values selected (in the active flight plan). At last, the runway is also drawn at a greater scale with the lower range values selected.

4 ARC mode
_
R (Ref. Fig. 022)
In this mode, the ND displays a 90 deg. heading sector ahead
of the A/C, giving the A/C magnetic heading with respect to
the fixed yellow reference line at the top of the scale.
The same difference as in the ROSE modes is made regarding the
basic mode selected for AFS operation: HDG or TRACK.
The A/C position on the map is represented by the fixed yellow
A/C symbol located at the lower quarter and at the mid of the
ND image, pointing up to the magnetic heading reference line.
This mode provides the pilot with exactly the same information
as the ROSE- NAV mode but limited to the forward 90 deg.
sector. Four arcs of a circle give range marks, scaling the
map according to the selected range value. The outer arc is
that of the heading scale.
Range marker values in NM are provided on the L and R lower
radials making a 15 deg. angle with respect to the horizontal.
R (Ref. Fig. 022, 023, 024, 025)
NOTE : In the ROSE-NAV and ARC modes, the VOR bearing pointers____
can be used to cross-check the accuracy of the A/C
position on the map.
These figures show:
- an example of a typical primary en route flight plan
- a configuration with the A/C off the flight plan
- ND in ARC mode with the A/C ready for takeoff.
5_ PLAN mode
R (Ref. Fig. 026)
The ND displays a static map orientated with respect to the
true North.
The information displayed is the same as the one in ARC mode,
but not ahead of the aircraft:
the map is centered on a Map Reference Point which is chosen
by the pilot on his MCDU and which can be:
- either the active waypoint
- or any other selected waypoint of the flight plan.
The scale of the map is the one chosen by means of the scale
selector switch (the range value selected corresponding to the
diameter of the outer circle).
The GS, TAS and wind data, and the active waypoint data are
displayed like in the other modes; but no navigation station
characteristics and associated bearing pointers are available
in this mode.
The A/C position on the map is represented by a
