Pilot's Guide
DESCRIPTION
The BFGoodrich Avionics Systems DME/TACAN Indicator displays
distance and azimuth information from VOR/DME, VORTAC and TACAN
ground stations. It also displays the station identifier, time to the selected
station and your groundspeed.
The indicator’s LED display is divided into four regions. The upper left
region displays distance information (in nautical miles) and the upper right
displays the station identifier. The lower left region displays the azimuth
to/from the station. The lower right region can be toggled to display either
the time-to-station (in minutes) or your groundspeed (in knots).
MODEL VARIATIONS
The DME/TACAN Indicator comes in a wide variety of models. All
models perform the same basic function – they display distance, azimuth,
identifier, time-to-station and groundspeed. Model variations are determined by the type of indicator controls, how the LED display brightness is
controlled, physical characteristics of the indicator, and whether the
indicator displays radial or bearing information. Each of the variations are
described in the following paragraphs.
Indicator Controls
The indicator’s controls are located on the faceplate, below the LED
display. The type of controls and the available control selections will
depend on the indicator model you have installed in your aircraft. Typically, the indicator has a control knob on the left side of the faceplate and a
pushbutton switch on the right. Models without a control knob still display
distance, azimuth, identifier, time-to-station and groundspeed. Models with
a control knob provide additional features and more control over how the
information is displayed.
1
DME/TACAN Indicator
These indicators are used with multi-channel DME/TACAN
Transceivers to display information from two tracking channels.
The standard DME/TACAN
indicator has a 5-position Selector Switch on the left side
of the panel. Switch selections for these models are OFF,
1, HOLD, 2 and BOTH.
Standard IN602 and ID-2502 Indicator
No-Hold versions of the indicator have a 4-position Selector Switch with positions for
OFF, 1, 2 and BOTH. No-Hold
versions have the same functionality as the standard indicator, except Hold Mode is not
available.
Similarly, No-Both versions of
the indicator have a 4-position
Selector Switch with positions
for OFF, 1, HOLD and 2. NoBoth versions have the same
functionality as the standard
indicator, except Both Mode
is not available.
2
No-Hold IN602 Indicator
No-Both IN602 Indicator
Pilot's Guide
These indicators are used with single-station DME/TACAN
Transceivers to display information from one tracking channel.
The IN602MD and ID-2472
have a dimming control knob
for manually dimming the display. The DIM knob is installed in place of the Selector
Switch.
IN602MD and ID-2472 Indicator
The IN605 incorporates a
larger bezel around the faceplate for mounting into a standard 3ATI panel cutout. The
IN605 may be mounted
through the front of the panel,
or flush mounted from the
rear of the panel. The only
control on the IN605 is the
page pushbutton.

DME/TACAN Indicator
LED Display Brightness
Most indicators contain a photocell to automatically control the brightness
of the LED display. A few versions use a rotary knob on the left side of the
faceplate (in place of the Selector Switch) which allows you to manually
control the display brightness. They have the same functionality as the
standard indicator for displaying information about a single (Nav1) station.
However, the OFF, NAV2, HOLD, and BOTH selections are not available on
the manually-dimmed versions.
Physical Characteristics
The DME/TACAN Indicator is offered in a wide variety of physical
configurations to accommodate many personal preferences and/or aircraft
installations. Model differences include the color and shape of the bezel,
the backlight voltage and even a NVG faceplate for use with night vision
goggles in military applications. These differences are purely cosmetic and
do not affect the operation of the indicator.

Pilot's Guide
Radial vs. Bearing Information
Some indicator models display the TACAN azimuth as radial from the
selected station; some display it as bearing to the station. The display is
software dependent and can be determined by the software version number
displayed during power up. Table 1 lists all available DME/TACAN
Indicator models and shows which ones display radial information and
which display bearing.

DME/TACAN Indicator
CONTROLS
SELECTOR SWITCH
Depending on the model of DME/TACAN indicator installed in your
aircraft, the Selector Switch may have switch setting for OFF, 1, HOLD, 2 or
BOTH. Each of these switch selections are described in the following
paragraphs.
OFF
Positioning the Selector Switch to OFF removes power from the
indicator and its DME/TACAN Transceiver.
1
When the Selector Switch is positioned to 1, the indicator displays
position information for the navaid station tuned by the Nav 1 radio.
HOLD When the Selector Switch is positioned to HOLD, the indicator will
hold the current display while you tune another station on the Nav
radio. This allows you to keep your position information displayed
while you change the Nav radio to an ILS frequency.
2
When the Selector Switch is positioned to 2, the indicator displays
position information for the navaid station tuned by the Nav 2 radio.
BOTH When the Selector Switch is positioned to BOTH, the indicator
simultaneously displays information about both navaid stations
tuned by the Nav 1 and Nav 2 radios.
PAGE PUSHBUTTON
When the Selector Switch is positioned to either 1 or 2, the PAGE
pushbutton toggles the lower right display to show either the time to the
selected station or your groundspeed.
6
Pilot's Guide
When the Selector Switch is positioned to BOTH, the PAGE pushbutton
toggles the lower left and right displays to show either the station identifiers
or the azimuth to/from the stations tuned by the Nav 1 and Nav 2 radios.
For models without a Selector Switch, the PAGE pushbutton always toggles
the lower right display to show either the time-to-station or your groundspeed.
DIMMING THE DISPLAY
Manually-dimmed versions of the indicator use a DIM knob on the left side of
the faceplate to control the LED display brightness. Rotate the DIM knob
clockwise to increase brightness;
counter-clockwise to decrease
brightness.
Models with a Selector Switch,
and models with no control on
the left side of the faceplate, use
a photocell to automatically control the LED display brightness.

DME/TACAN Indicator
OPERATION
All versions of the BFGoodrich Avionics Systems DME/TACAN Indicator
are capable of displaying distance to the selected navaid station, the station
identifier, the azimuth to/from the station, the time-to-station and your
groundspeed. The following paragraphs describe the basic operation of the
BFGoodrich Avionics Systems DME/TACAN Indicator.
IMPORTANT
We have documented the standard (5-position Selector Switch)
indicator model since it provides all operational features. The
features on other models of the indicator, if available, will perform the
same as described for the standard indicator.
We also refer to the position information displayed by the indicator
as azimuth to/from the selected stations. Since the display of TACAN
azimuth information is model/software-dependent, your indicator
may display position as radial from or bearing to the station. (Refer
to Table 1 for details.)
POWER ON
As with any solid-state avionics, the indicator should be turned on after
engine start. This will protect the circuitry from short duration, high line
voltages and will extend the life of your avionics equipment.
Rotate the Selector Switch from OFF to 1 (or 2) to turn the indicator on and
to apply power to its DME/TACAN Transceiver.
NOTE
Indicators that do not have a Selector Switch can be turned on through
the TACAN Control Unit. Depending on the type of control unit,
rotate the OFF/ON/VOL knob or position the OFF/ON toggle switch to
ON.
The indicator will run a test of the LED display segments, show you the
operational software versions of the indicator and transceiver, then perform
self-tests to ensure the system is operating properly. Each of these events
are discussed in the following paragraphs.
8
Pilot's Guide
LED Checkout and Software Version Display
When the indicator is turned on, an LED pixel test will scroll from right to left
along the upper and lower displays. Immediately following the LED pixel test,
the indicator will display the software version of the indicator and its
associated DME/TACAN Transceiver. The indicator (IND) version
is displayed on the upper display and
the transceiver (TCN) version is displayed on the lower display. The
software version information will remain displayed for approximately 3 seconds. (The software versions of your
equipment may not necessarily be the same as those depicted in the illustration.)
System Self-Tests
After the software versions have been displayed, the system will perform a
series of self-tests and annunciate the results before proceeding. If no
problems are detected during the self-tests, the indicator will display the
SELF TEST PASS message.
If SELF TEST FAIL appears, the lower right display will show a failure
code number. The failure code number will assist the technician in troubleshooting the system. Always note the failure code number prior to turning
the indicator off. The following briefly describes the failure codes that may
appear during the self-test.

DME/TACAN Indicator
DISPLAYING NAVIGATION INFORMATION
When the Selector Switch is positioned to 1, the indicator displays information for the navaid station tuned by the Nav 1 radio. If your aircraft is
equipped with dual navigation radios, positioning the Selector Switch to 2
will display information for the station tuned by the Nav 2 radio.
NOTE
When first turned on, the indicator
will display a series of dashes (– – -)
until the transceiver locks onto the
tuned station.
Distance and Azimuth Information
Distance from the navaid is displayed in the upper left region. The indicator will display your distance up to 400 nautical miles from the station in 1
nautical mile increments. Under 100 nautical miles, the indicator will
display distance in tenths of miles. The azimuth to/from the navaid is
displayed in the lower left region.
NOTE
The distance is measured in nautical miles on a slant from the aircraft
to the ground. This is commonly referred to as slant-range distance.
Slant-range distance approximates 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 you’re at higher altitudes and close to the VOR/
DME or TACAN ground station.
10
Pilot's Guide
Time-to-Station and Groundspeed Information
The DME/TACAN Transceiver calculates your groundspeed based on Nav
1 or Nav 2 computations. Pressing the PAGE pushbutton toggles the lower
right region to display your groundspeed or your time-to-station.
Time is displayed from 0 to 99 minutes in 1 minute increments. Groundspeed is displayed from 0 to 999 knots in 1 knot increments.
For groundspeeds greater than 999 knots, the time-to-station and the
groundspeed displays will be "dashed", although the DME/TACAN
Transceiver may continue to track the station at a higher rate.
If two stations are being tracked and the groundspeeds to each station are
different, the indicator will display the fastest groundspeed, regardless of
the Nav1/Nav2 selection by the Selector Switch.
Visual and Audible Station IDENT
The alphanumeric identifier of the selected navaid is displayed in the upper
right region. The indicator will display “Nav1” or “Nav2”, as applicable,
until the identifier is decoded.
An audio station identifier will be output from the DME/TACAN Transceiver corresponding to the position of the Selector Switch. When the
Selector Switch is set to 1, the identifier from the station tuned by the Nav 1
radio will be audible. When the Selector Switch is set to 2, the identifier
from the station tuned by the Nav 2 radio will be audible.
11
DME/TACAN Indicator
Frequency and Channeling Information
You can display the VOR frequency or TACAN channel that you have
tuned on your Nav 1 and Nav 2 radios. This mode would be especially
useful in the event of a Nav radio readout failure. Even though you
couldn’t view the readout while tuning the Nav radio, you could monitor
the DME/TACAN Indicator display to see the frequency or channel you
have selected.
Position the Selector Switch halfway between any of the detent positions
(OFF , 1, HOLD , 2 or BOTH). The indicator will display the VOR frequency tuned by your Nav 1 radio in the lower left region of the display.
The Nav 2 frequency, if applicable, will be displayed in the lower right
region. If you press the PAGE pushbutton, the indicator will display the
equivalent TACAN channel for the tuned station(s).
HOLD MODE – RETAINING THE DISPLAY WHILE TUNING
The Hold feature allows you to hold the current display on the indicator
while you tune another station on the Nav radio. You may want to use this
mode to keep your position information displayed while you change the
Nav radio to an ILS frequency.
First, rotate the Selector Switch to 1 or 2 to identify the station to be placed
on hold. Then, rotate the Selector Switch to HOLD. The Indicator will
continue to display distance, azimuth, and station identifier while annunciating “HOLD” in the lower right region of the display. The audio identifier
for the station on hold will remain audible.
12
Pilot's Guide
The PAGE pushbutton serves no function when the Selector Switch is
positioned to HOLD. However, the lower right display will toggle from
“Hold” to “HOLD” to let you know the switch is functioning.
NOTE
For No-Hold versions of the Indicator, the Hold Mode may be
initiated by an external control head equipped with a HOLD function.
BOTH MODE – DISPLAYING MORE THAN ONE STATION
The Both feature allows you to display position information from both
stations channeled on the Nav radios. The upper left display shows the
nautical miles from the station tuned by the Nav 1 radio. The upper right
display shows your distance from the station channeled on Nav 2.
Pressing the PAGE pushbutton toggles the lower displays to show the
corresponding station identifiers or your azimuth to/from the stations.
If the selected station (Nav1 or Nav2) does not provide adequate signal for
distance calculation, the indicator will continue to display groundspeed
based on the "unselected" station's signal. Remember: it displays the fastest
groundspeed, regardless of the Nav1/Nav2 selection by the Selector Switch.
There is no audio station identifier output available from the DME/TACAN
Transceiver when the Selector Switch is set to the BOTH position.
13
DME/TACAN Indicator
FLAG CONDITIONS
The indicator will display several types of flags to alert you to certain
conditions that as they occur. Each of the flags are discussed in the
following paragraphs.
IDENT Decoding
The DME/TACAN Transceiver will decode the Morse Code identifiers of
the tuned navaid station(s). The decoded, alphanumeric identifier is then
displayed on the indicator for you to confirm the proper station is selected.
When you tune the Nav radio to another station, the indicator will display
“Nav 1” and/or “Nav 2” flags, as applicable, until the new identifier is
decoded.
NOTE
Pilots are required to aurally identify the audible IDENT signal to
confirm that the transceiver’s IDENT decode display is accurate. The
audio signal can be monitored by positioning the Selector Switch to
1 (or 2 as applicable) and turning the DME audio panel controls to
speaker or headphone, as required. There is no audio IDENT when
the Selector Switch is positioned to BOTH.
DME Only
Some frequencies that you tune may provide only DME information, or
may transmit VOR bearing signals instead of TACAN bearing. Whenever
one of these stations are tuned, the indicator will post the “DME” flag in the
lower right region instead of displaying directional information.
14
Pilot's Guide
Loss of Position Information
The indicator will display “loss of data” flags whenever the VOR/DME or
TACAN stations cannot provide accurate distance or azimuth information.
The flags are identified by a series of dashes (– – –) in the respective
display region.
Loss of Groundspeed/Loss of Time-to-Station Display
The indicator will display “loss of data” flags (dashes) for the groundspeed
and time-to-station displays when:
1.
Your groundspeed exceeds 999 knots (although the DME/TACAN
Transceiver may continue to track the station at a higher rate),
2.
Your time-to-station exceeds 99 minutes,
3.
The system calculates your new groundspeed or time-to-station.
(This should only occur within 30 seconds of the last channel change
or station lock on.)
LIMITATIONS
Table 2 shows the effective line-of-sight range (in nautical miles) based on
your aircraft's altitude (in feet) above ground level (AGL).

DME/TACAN Indicator
SYSTEM INTERFACES
The DME/TACAN Indicators can be used with a variety of BFGoodrich
Avionics Systems DME or TACAN Transmitter/Receivers. Other features
may be available, depending on your system configuration.
Air-to-Air Ranging
Air-to-air ranging may be accomplished between two aircraft when each is
equipped with an airborne TACAN system compatible with MIL-STD291B. Air-to-air ranging can be activated as follows.
1.
Place the Air/Ground-Air/Air Mode switch on each aircraft’s TACAN
Control Unit in the A/A position.
2.
Tune the TACAN Control Units to channels that are 63 channels apart
(such as Channel 20 in one aircraft and Channel 83 in the other).
Refer to Table 3 for a list of TACAN channels and their corresponding VOR frequencies.
3.
Place the X/Y Mode switch on each aircraft’s TACAN Control Unit in
the same position (both to X, or both to Y).
16
Pilot's Guide
Once both aircraft have successfully activated air-to-air ranging, the DME/
TACAN Indicator can be used to monitor position information relative to
the two aircraft. The upper left region will display the distance between the
two aircraft. The upper right region displays the “A/A” flag to remind you
that air-to-air ranging is activated. Pressing the PAGE pushbutton will
toggle the lower right display to show either the time-to-rendezvous or the
rate of closure between the two aircraft.
The time-to-rendezvous is displayed from 0 to 99 minutes in 1 minute
increments. The rate of closure is displayed from 0 to 999 knots in 1 knot
increments.
Since azimuth information is not available in the A/A mode, the lower left
display will always show “DME” when air-to-air ranging is selected.
