4. Active Traffic
a. Active Traffic Enable: Select Disabled, TAS, or TCAS. This function must be enabled for
installation with TAS/TCAS ((NGT-9000+, D+, or NGT-9000R+, RD+).
• This feature requires a function activation code. Refer to the general information section of
this manual for details on how to obtain this code.
• This feature requires a Mode S Identifier to be entered. If the Mode S Identifier is modified
the diversity and TAS/TCAS enable options, if currently enabled, will be disabled. See the
maintenance section for details.
• When enabled the aural alert "Traffic" and the clock bearing callout (e.g., 12 O'clock) is
heard over the audio system when traffic advisory (TA) is first detected.
• When enabled, while a traffic advisory (TA) is active, the Traffic Alert lamp is illuminated.
b. Ground Filtering Altitude: This option sets the altitude the display of traffic is shown.
• This feature requires "Active Traffic Enable" or "ATAS Enable" to be enabled.
• The “Standard” selection inhibits the display of traffic below 380ft AGL.
• The “Alternate” selection inhibits the display of traffic below 5ft AGL.
c. Directional Antenna Type:
• This feature requires "Active Traffic Enable" or "ATAS Enable" to be enabled.
• Select either NY164 (TAS) or NY156 (TCAS).
5. Traffic Extended Callout Enable:
• This feature requires "Active Traffic Enable" or "ATAS Enable" to be enabled.
• When enabled the extended aural alerts heard over the audio system when traffic advisory (TA)
is first detected. The extended callout consists of "Traffic", clock bearing, relative altitude,
range, and vertical sense (e.g., Traffic, 2 o’clock, low, 2 miles, climbing).
• The callouts have the following parameters: Relative altitude terms are High, Low, Same
Altitude, or if Relative altitude is unknown (NAR). Range values are in whole nmi starting with
less than one mile, one mile, two miles, and ten miles (ten miles is used for all ranges greater
than or equal to 10 nmi). Vertical Sense terms are climbing, descending, level, or NAR (if
vertical rate is unknown).
6. Antenna Installation: This setting is dependent on both the TAS/TCAS enabled and diversity
enabled settings. The options available change depending on current Diversity enabled and
TAS/TCAS enabled settings. Select the antenna installation using the following guidelines.
• When Diversity is disabled and TAS/TCAS is disabled, then the only valid antenna selection is
Bottom Omnidirectional only.
• When Diversity is enabled and TAS/TCAS is disabled, then the only valid antenna selection is
Bottom Omnidirectional/Top Omnidirectional.
• When Diversity is disabled and TAS/TCAS is enabled, then antenna install may be either
Bottom Omnidirectional/Top Directional or Bottom Omnidirectional/Bottom Direction.
• When Diversity is enabled and TAS/TCAS is enabled, then the only valid antenna install is
Bottom Omnidirectional/Top Directional
Note - When changes are applied, validation occurs and if a valid option is not selected then a
warning message is shown. No changes are applied.
