1.4.9 Traffic Alert
Traffic Alert is a discrete output that provides an indication (lamp) of a TAS, TCAS, or ATAS Traffic
Advisory. The TAS, TCAS, and ATAS are configuration options that are set during installation.
The TAS traffic advisory requires the Lynx NGT-9000 models with the TAS option (+, D+, R+, or
RD+).
The ATAS traffic advisory is an option that can be used by any model of the Lynx NGT-9000 with
Release 2.0 and later.
The TCAS traffic advisory is an option that can be used by any model of the Lynx NGT-9000 with
Release 3.0 and later.
1.4.10 TAWS Caution and Warning Alert
Available with Release 2.0 and later, the TAWS Alerts are discrete outputs that provide an indication
(lamp) of a terrain or obstacle Caution or Warning Alert.
Available with Release 2.1 and later, TerrainVision
TM
is a Terrain Advisory with no audio or visual
alerting is available for panel mount NGT-9000.
1.4.11 WiFi Interface
The unit uses a RS-232 bus to interface with the PIM-9000 RS-232. This interface provides traffic and
weather information on a personal electronic device via a software application (APP).
1.4.12 WOW Input
The WOW input discrete is optional. The input signals the On Ground status to the unit via squat switch,
Airspeed monitor, or a collective switch.
Do not connect this to a gear switch or a manual pilot switch input.
An internal algorithmic override that uses ground speed and altitude inputs may override this input
and change the air/ground state (ex. a WOW "in-air" state could be changed back to on ground if the
Aircraft is sitting on the ground). This is expected behavior. If simulated in-air test is required, use
the ground test mode.
1.4.13 Maintenance Interface
The unit can interface to a maintenance computer using either the WiFi interface or the USB port located
on the front of the unit. This interface is used for installation setup and fault isolation and is only available
while on ground.
1.4.14 GPS Antenna
Antenna performance is critical to the operation of the Unit. The unit requires that the GPS Antenna meet
performance requirements specified in TSO-190. Refer to paragraph 1.11.2.
1.4.15 L-Band (978/1030/1090 MHz) Antenna
The L-Band antenna is used by the Unit to receive 978 MHz, 1030 MHz, and transmit/receive 1090 MHz.
If the NGT-9000 is configured for Diversity, then two L-Band antennas are required. If the TAS or TCAS
and Diversity option (models D+ or RD+) is used then a top directional antenna may be used instead of the
top L-Band antenna. Refer to paragraph 1.11.3.
