_ This pushbutton switch, when pressed, enables the pilot to have the LOC and GLIDE scales and deviation symbols on his PFD. Its three light bars then come on green. Pressing it again, the light bars go off and the ILS deviation indications disappear from the PFD. At last this pushbutton switch controls the audio selection for DME stations (enabling ILS/DME).
Pressing this P/B switch also controls the display of the QFU symbol (ILS course) on the heading scale of the PFD and on the ND, plus the display of the LOC deviation bar on the ND in the ARC and ROSE-NAV modes.
(b) ND control
1 Mode selector switch
_ This mode selector switch enables each pilot to have the desired presentation of navigation information on his ND:
-
in ROSE mode, a full heading dial is presented, orientated to the A/C present heading. Three sub-modes are available: ROSE-NAV: the flight plan is presented, with the A/C position in it and the navaids positions ROSE-VOR: this sub-mode gives the classical HSI presentation, with the VOR deviation with respect to the selected course ROSE-ILS: Ditto, but with the LOC deviation information, with respect to the selected ILS course
-
in ARC mode, only the 90 degrees heading sector ahead of A/C is shown. The flight plan is presented, including the aircraft position and the navaids positions.
-
in PLAN mode, a full heading dial is presented, but orientated to the geographic North. The flight plan is drawn, and any waypoint of the flight plan can be positioned at the center of the heading dial, through MCDU controls. The present position of the A/C in the flight plan is given (by means of a true track directed A/C symbol).
NOTE : The WXR picture is available in the ARC and ROSE-NAV,
____ ROSE-ILS and ROSE-VOR modes. Activation of the WXR is made through the WXR control unit. When the ND selected mode is the PLAN mode for both NDs, the WXR is automatically disabled.

2_ Scale selector switch
This selector switch enables each pilot to select the desired scale factor for the presentation of navigation and weather radar information on his ND, among those values: 10, 20, 40, 80, 160, 320 nautical miles.
3_ ADF-VOR bearing switches These 3 position switches enable each pilot to have ADF and/or VOR bearing pointers displayed on his ND, as well as the corresponding NAV station characteristics, in any mode except the PLAN mode.
4_ Selection of navaids stored in the FMGC data base
In addition to the data which are permanently displayed in PLAN, ARC or ROSE-NAV mode, further optional data can also be displayed through five pushbutton switches marked CSTR, WPT, VOR-D, NDB, ARPT respectively. Each of these pushbutton switches has an exclusive function, which prevents cluttered display of information on the image. The option selected is indicated by bars coming on on the corresponding pushbutton switch. ARPT pushbutton switch. When pressed, the bars come on green, and all the airports in the zone are presented on the Navigation Display. NDB pushbutton switch. When pressed, the bars come on green, and all the ADF ground installations are presented on the Navigation Display. VOR-D pushbutton switch. When pressed, the bars come on green, and all the VOR, DME and VOR/DME ground installation in addition to the tuned Navaids are presented on the ND. WPT pushbutton switch. When pressed, the bars come on green and all waypoints other than those included in the flight plan are presented on the ND.
