with the TRK FPA modes, the A/C symbol is dimmed and the flight path vector symbol appears, giving the A/C actual flight path angle and drift angle (track), whatever the FD P/B switch status.

-Guidance Either of these two modes of presentation of the Flight Director orders is available, depending on the HDG V/S -TRK FPA choice:
*
conventional crossed bars, pitch and roll, plus yaw bar
for T.O. and LAND modes.
(Ref. Fig. 018)
*
flight path director symbols: in relation with the flight
path vector, they give the FD orders in flight path and in
track.
(Ref. Fig. 017)
Obviously, the guidance orders are presented on a given PFD provided that the FD pushbutton switch bars on the respective EFIS control section is on in green color, which corresponds to the FD ON selection. Moreover, at least one FD must be engaged.
(b) Navigation display Each pilot has 5 different modes of presentation of his ND at his disposal:
-
ROSE ILS
-
ROSE VOR
-
ROSE NAV
-ARC
-PLAN. (Ref. Fig. 019, 020, 021) In the three ROSE modes, the ND provides an image similar to that of a conventional horizontal situation indicator, i.e. a rotating heading dial orientated to the magnetic North and giving to the pilot the A/C actual magnetic heading with as reference the fixed yellow lubber line at the top of the dial. The ND display is always heading up. A yellow A/C symbol, at the center of the heading dial, is fixed and pointed up to the yellow lubber line.
Above 73. North or 60. South, the TRU indication is displayed above the heading indication.
Small white triangles are arranged in the 45 deg positions on the circumference with as reference the aircraft lubber line. They are fixed and do not turn with the heading dial. A green diamond-shaped symbol moving around the heading dial gives the A/C actual track. If a value is displayed on the HDG TRK counter of the FCU, it is represented on the ND by a cyan triangle moving around the heading dial.

1 ROSE-ILS mode
_
R (Ref. Fig. 019) If an ILS station frequency and course have been selected (manually or automatically):
-
a dagger-shaped pointer in magenta color points to the selected ILS course. Its center part is the lateral deviation bar, which can move on a scale perpendicular to the pointer, and has 2 dots on each side. The position of the bar on the scale gives the localizer deviation. The extreme dots correspond to plus or minus 0.155 ddm (plus or minus 150 microamp.)
-
a magenta lozenge gives the glide slope deviation on a vertical scale, at the right of the heading dial, provided that the A/C is within the conditions of reception of the ILS glide slope signal. The extreme dots correspond to plus or minus 0.175 ddm (plus or minus 150 microamp.)
-the selected ILS station side, frequency, course, and identification when available are displayed in the right upper corner of the ND
-at the top and in the middle, the ILS APP message appears
when an ILS approach has been selected on the MCDU. In the left upper corner, the A/C actual ground speed and true airspeed indications are provided, as well as the wind data (direction/force: the direction is given with respect to the true North in digital form, and with respect to the heading dial axis (aircraft heading) in analog form (arrow).
