 -in the right upper corner of the ND, the VOR station characteristics are presented: selected VOR station side, frequency, selected course, identification if available.
 -at the top of the ND and in the middle, the VOR APP message is displayed if the pilot has selected a VOR approach on the MCDU.
 -There is no vertical deviation scale at the right of the
 heading dial. The navigation station characteristics and bearings, and the chrono indications are available exactly like in ROSE-ILS mode.
ROSE - NAV mode (Ref. Fig. 020) The A/C actual magnetic heading, track and associated selections are presented exactly like in ROSE-ILS and ROSE-VOR Modes. The GS, TAS and wind data, the type of approach (ILS APP or RNAV APP or VOR APP or NDB APP), and all the navigation station characteristics and bearing pointers are also presented exactly like in ROSE-ILS and ROSE-VOR modes. The difference lies in the presentation of map data elaborated by the FMGC. The image is scaled according to the range mark value selected by the pilot on his EFIS control section. Two range markers laid on the 225 deg. radial indicate the value in NM of the distance represented by the radius of the two range circles (inner and outer), the latter being the rose heading scale circles. These values are respectively the 1/4 and the 1/2 of the selected range (which represents a distance equal to that of the ROSE diameter). The map data include various types of flight plans (active, secondary, temporary, alternate, offset, engine out), with the successive waypoints they link. The active waypoint is the next one to be overflown by the A/C. Since it represents the next objective, the associated data are displayed in the ND top right corner:
 1EFF : 106-149, 303-399, 1 31-60-00Page 44 1 1 Config-3 Aug 01/05 1 1 1CES 1 waypoint identification, bearing to go, distance to go, and estimated time at arrival, instead of the ILS or VOR station characteristics in ROSE-ILS and ROSE-VOR modes respectively. 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, if he presses the desired pushbutton switch on his EFIS control section, each pilot can have on request additional information displayed:

 -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 which
 surround waypoint.
 These symbols are in magenta when associated to a constraint
 (in altitude or speed).
 The holding patterns and procedure turns are represented as
 follows:

 -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.

ARC mode (Ref. Fig. 021) In this mode, the ND displays a 90 deg. heading sector ahead of the A/C. It gives 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. It points 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. (Ref. Fig. 021, 022, 023, 024)
 NOTE : In the ROSE-NAV and ARC modes, the VOR bearing pointers
____ are 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.
