TRAJECTORY DEVIATION
Applicable to: ALL
ILS APPROACH
(1) Localizer Deviation Scale and Index
(2) Glide Slope Deviation Scale and Index
Deviation scales appear as soon as the flight crew pushes an LS pushbutton switch on the
EFIS control panel. Deviation indexes appear when the glide slope and localizer signals are
valid if deviation scales are displayed.
When a deviation index is out of the displayed range, only half a symbol appears at the end
of the scale.
The LOC scale flashes and continues to flash if the deviation exceeds 1/4 dot for two
seconds (above 15 ft RA). The glide scale flashes and continues to flash if the deviation
exceeds one dot for two seconds (above 100 ft RA).
"LOC" and the glide scale half index symbols flash and continue to flash when the deviation
exceeds two dots for two seconds.

One dot represents a deviation of ± 0.8 ° on the localizer scale and ± 0.4 ° on the glide slope
scale.
Applicable to:
ILS APPROACH (CONT'D)
(1) ILS information (magenta)
The following information appears on the PFD, when the crew has selected an ILS frequency
and course and pushed the LS pushbutton :
• ILS identification as decoded by the ILS receiver
• ILS frequency
• DME distance if the ILS has a DME
(2) ILS course Pointer (magenta)
This pointer appears on the PFD, when the crew has selected an ILS frequency and course
and pushed the LS pushbutton.
It is a dagger-shaped symbol on the heading scale.
The ILS course (numerical) appears in magenta on the right or the left side of the scale when
it is outside the displayed range of headings.
(3) Marker Indications
OM appears in cyan, when the aircraft flies over the outer marker
MM appears in amber, when the aircraft flies over the middle marker
AWY appears in white, when the aircraft flies over an airways marker beacon or the ILS
inner marker.
(4) ILS Message
This flashes amber, when the APPR mode is armed and the ILS display is not selected.

It is a dagger-shaped symbol on the heading scale.
The ILS course pointer is replaced by digits on the right or left hand side of the heading scale
(in a white box), when the ILS course value is outside the displayed portion of the heading
scale.

IM appears in white, when the aircraft flies over an airways marker beacon or the ILS inner
marker.

Applicable to:
NON PRECISION APPROACH
(1) Vertical Deviation Scale and Index
The vertical deviation scale and index appear when in approach phase and the FINAL
mode is armed/engaged or a non precision approach has been entered. They are displayed
until MDA has been reached. They give the vertical deviation with respect to the trajectory
defined by the FMGC.
Each index scale graduation represents 100 ft. The range is ± 200 ft.
Note: If LS pushbutton is pressed, glide deviation has priority over vertical deviation
information.
