R
In the left and right lower corners, the pilot is provided with the characteristics of the navigation stations (ADF and/or VOR) the bearing of which he needs. Each pilot has at his disposal two 3 position selector switches on his EFIS control section, one ADF - OFF - VOR side 1 and one ADF - OFF VOR side 2. When he sets a selector switch to ADF or VOR, the following characteristics of the corresponding navigation station are displayed on either of the ND lower corners, left for side 1 stations, and right for side 2:
-type of station (ADF or VOR)
-shape of the associated bearing display (if the bearing data is available)
-station identification (or frequency by default)
-mode of tuning (nothing if the station has been automatically tuned by the FMGC, M underlined if the station has been manually tuned by the pilot and R underlined if the station has been tuned from an RMP)
-DME distance for a VOR-DME or a DME station.
If the bearing data are available, the corresponding bearing
pointer is presented on the heading dial.
Color: green for the ADFs and white for the VORs.
The station characteristics are displayed in the same color as
their corresponding bearing pointer.
The DME indications, when provided are in green color.
By design, a maximum of 2 bearing pointers can be presented
simultaneously on the display:
ADF 1 The shape of the pointers has been
VOR 1 carefully studied so as to avoid any
ADF 2 confusion.
VOR 2 Graphic priority is associated to the
ADF 1 - ADF 2 side 1 pointers, so that they overlay
ADF 1 - VOR 2 the side 2 pointers when the side 1
VOR 1 - ADF 2 and 2 navigation station bearings are
VOR 1 - VOR 2 nearly identical or differ from 180..
In addition, a chronometer indication is available in digital
form (green digits on a grey background shaded area).
(Ref. Fig. 020)
This chrono gives the minutes and the seconds from 0 to 59mn
59s, then the hours and minutes up to 99h 59mn.
The chrono operation is controlled by means of the CHRONO
pushbutton switch (beside the EFIS control section):
-1st action: the display appears and the chrono starts counting on the P/B
-2nd action: the chrono stops counting but indication remains displayed
-3rd action: the display disappears and the chrono is reset.

2 ROSE - VOR mode
_
R (Ref. Fig. 020)
This presentation is identical to the ROSE-ILS one, except for
the following points:
- the dagger-shaped pointer points to the selected VOR course;
it is displayed in cyan color.
The lateral deviation bar stands for the VOR deviation, the
extreme dots of the scale corresponding to plus or minus 10
deg. In addition, an arrow on the bar gives the TO/FROM
indication.
- 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.
3_ ROSE - NAV mode
R (Ref. Fig. 021)
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
