function is designed into both
indicators to adjust the brightness of
the display to compensate for
changes in the ambient light level.
The NAV Frequency Selector
proveds frequency selection for the
NAV receiver (including glideslope
channels) as well as DME channels.
The desired navigation frequency is
selected by use of two controls
located on the front panel. The large
(inner) control is used to increase or
decrease the navigation frequency in
one MHz increments from 108.00MHz
to 117.00MHz. The small (outer)
control is used to increase or
decrease the navigation frequency in
50 KHz increments. The frequency
selected is displayed in the “frequency
window”.
The DME system provides an
audio output capability allowing the
pilot to identify the DME ground
station by listening to the CW tones
transmitted by the ground station at
30-second intervals.
weather, type of terrain, location and
altitude of the ground transmitter and
transmitter power. Usually line-of-sight
limitations will prevent an aircraft on
the ground from receiving and locking
on to a TACAN or VORTAC ground
station. Typical operating distance
versus altitude is shown in
Table 1 .
The range measurement portion
of the KTU 709 TACAN system
electronically converts elapsed time-
to-distance by measuring the length of
time between the transmission of a
radio signal to a pre- selected TACAN
or VORTAC station and reception of
the reply signal. This distance is then

572/573/574 When Used
With the KTU 709
The KTU 709 TACAN system is a
polar coordinate UHF navigation
system that provides relative bearing
and slant-range distance information
with respect to a selected TACAN or
VORTAC ground station. The effective
range of the TACAN is limited to the
line-of-sight. Actual operating range
depends on the altitude of the aircraft,
