Reception of ILS Signals
When the
FTA-750L/FTA-550
receive an ILS (instru-
ment landing system) signal, the display will automati-
cally switch to the NAV band screen which shows a
CDI (course deviation indicator) based on the received
signal, and “
LOC
”, which indicates that the
FTA-750L/
FTA-550
are receiving the localizer signal, and “
GS
”,
which indicates that the
FTA-750L
is receiving the
glide slope signal, appear on the display.

In the
FTA-750L
when the internal GPS unit is not
activated or cannot receive a fix even it is activated,
or in the
FTA-550
, the upside of the compass rose
always indicates the direction of the runway and no
sign indicating the bearings is displayed on the com-
pass rose.
In the
FTA-750L
when the internal GPS unit is ac-
tivated and receives a fix, the compass rose rotates
to display the approaching course up. The course
indicator, deviation marks, and deviation needle also
rotate to display the runway direction if registered in
advance.
