Civil Operation

Active Entry

The Active Entry mode is entered
by pressing and holding the Transfer
button for more than 2 seconds. The
frequency displayed in the Active
window may then be changed with the
Frequency Control knobs in the same
manner as described above. The
receiver will be tuned to the frequency
displayed in the Active window at all
times.

Momentarily pressing the
Transfer button will return the control
unit to the Standby Entry mode. The
Standby frequency displayed prior to
entering the Active Entry mode
remains unchanged.

Channel Mode

A. Momentarily pressing the
CHAN button while in Frequency
mode puts the unit in Channel mode.
The unit remains tuned to the last
active frequency displayed before
entering Channel mode. The last
used channel number is displayed
unless no channels have been
programmed, in which case the unit
defaults to Channel 1 and dashes are
displayed in the Standby window.

Turning either tuning knob
changes the channel number and
corresponding frequency. The
channels will only increase and
decrease to channels that have been
programmed. If there has been no
activity for five seconds the unit will
return to Frequency mode and the
channel frequency is placed in the
Standby window. Pressing the CHAN
button before the 5 second delay is
completed will return the unit to
Frequency mode and the status of
Frequency mode prior to entering
Channel mode remains the same.

B. When in Channel mode,
pressing the Transfer button will return
the unit to Frequency mode. The
channel frequency will become the
new Active frequency and the last
Active frequency will become the new
Standby frequency. If the unit was in
Active Entry mode prior to entering
Channel mode, pressing the Transfer
button or allowing the unit to time out
will bring it back to Standby Entry.

Program Mode

A. Program mode is selected by
pressing and holding the CHAN button
for longer than two seconds. The unit
tunes the KTR 908 to last active
frequency displayed before entering
Program mode and the last used
Channel number is displayed when
Program mode is entered. The
Channel number flashes and turning
either tuning knob changes the
Channel number. When the Channel
number is flashing, pressing the
Transfer button will cause the Channel
number to stop flashing and cause the
frequency to flash, unless the channel
is Program Secured. The secured
mode prevents the pilot from changing
the programmed channels. This is
accomplished by a strap in the aircraft
wiring.

The tuning knobs then work as in
Frequency mode, except between
rollover points 118.XX to 136.XX and

136.XX to 118.XX, or 118.XX to

151.XX and 151.XX to 118.XX for
extended frequency range, dashes are
displayed to unprogram the channel.
When frequency is flashing, pressing
the Transfer button will cause the
frequency to stop flashing and the
Channel number to flash allowing the
next channel to be programmed.

B. If no activity has occurred for
20 seconds the unit returns to
Frequency mode. The unit can also

4

be returned to Frequency mode from
Program mode by pressing the CHAN
button. Returning to Frequency mode
will not change the Active or Standby
frequencies from what they were prior
to entering Program mode.

DME

KDI 572/573/574 When Used With the KDM 706/706A

The effective range of a DME
depends on many factors: most impor­tant being line of sight limitations
determined by the altitude of the
aircraft (see Table 1), weather, the
location and altitude of the ground
transmitter and transmitter power
output. The degree of maintenance of
the KDM 706/706A DME and
maintenance of the ground station also
contribute to a DME's effective range
capability. Usually line-of-sight
limitations will prevent an aircraft on
the ground from receiving and locking
onto a VORTAC station.

The DME system electronically

converts elapsed time-to-distance by
measuring the length of time between
the transmission of a radio signal to a
pre-selected VORTAC station and
reception of the reply signal. This
distance is then indicated in nautical
miles on the DME range/ground
speed/time-to-station indicator. This
distance is measured on a slant from
the aircraft to the ground and is
commonly referred to as slant-range
distance. Slant-range distance should
not be confused with actual ground
distance. The difference between
slant-range distance and ground
distance is smallest at low altitude and
long range. These distances may
differ considerably when in close
proximity to a VORTAC facility.
However, if the range is three times
