The compass display is very
conventional. The gray scale moves
against a fixed yellow line which
represents the centerline of the
aircraft. In the example shown the
aircraft is heading 091 degrees.
HEADING 091

The small green diamond
represents the aircraft track, and it is
normally referred to as the TRACK
DIAMOND.
In the example shown the track is
094 degrees which means that the
aircraft has 3 degrees of drift to the
right.

There is a direct relationship
between the small white ticks on the
horizon line of the attitude indicator
and the compass scale.
As the heading changes the ticks
move to stay in line.
Now let’s look at how ILS
information is displayed and in
particular concentrate on the
compass scale.

The ILS pb on the EFIS control panel
enables the pilots to switch on an ILS
display.
EFIS MENU
PFD Presentation 84/97
The ILS display includes indications for:
• Localizer,
• Front course,
• Glide slope,
• Information.
EFIS MENU
PFD Presentation 85/97
ILS deviation information is
displayed in the form of Localizer
and Glideslope deviation scales.
The ILS front course will be
displayed in magenta at the side of
the compass scale if the figure is
outside the visible scale.

A magenta diamond represents the
localizer.
When the ILS front course is
within the compass scale it is
displayed as a magenta dagger.

In the example shown the aircraft
is established on the localizer and the
Glideslope indication has appeared in
