ALTERNATE DISPLAy
An alternate display may be interfaced to the Lynx NGT-9000, but care
must be taken to insure that there is not a conflict of input commands.
Use the following guidelines when using an alternate display:
Refer to the operations manual for the alternate display for
instructions.
Check with your dealer or with L-3 Avionics Systems for a current
list of compatible alternate displays.
Lynx NGT-9000 can provide Traffic (ADS-B and TAS) via ARINC
429 and Traffic/FIS-B Weather via RS-422.
Some alternate displays have the same display ranges as the Lynx
NGT-9000, while others generate their own display ranges.
The look of traffic screens on alternate display may vary. Details
on alternate display symbology is shown below. Displays using
conventional ARINC 735 TIF traffic will only depict TA, Proximate
and other traffic. Displays using the new ARINC 735B DTIF traffic
can depict all the listed traffic symbols noted below.
Other Traffic Symbol
On alternate displays the Other Traffic (OT) symbol represents an
intruder aircraft that has been detected within the selected display
range and vertical display mode, but which has not generated a TA or
a PA. The symbol is white or cyan on color alternate displays.
On some alternate displays, OT symbols disappear when a TA occurs,
and reappear (if still in range) once the TA goes away. Some alternate
displays can also have options set to filter out all OT symbols.

When the GPS has “failed”, the lamp is “ON”. GPS failures
happen when:
The Lynx NGT-9000 internal GPS indicates a failure.
Aircraft is On-Ground and the GPS has acquired position, but
the signal is lost for more than 2 minutes.
Aircraft is In-Air and the GPS has not acquired position within
2 minutes (either startup or had position and lost it).
5. The lamp begins to flash for the following reasons:
Aircraft On-Ground, there is a 2 minute “quiet period” when
the GPS is expected to acquire position. After 2 minutes, the
lamp will flash indefinitely while the GPS has never acquired,
but is not failed.
Aircraft In-Air, at startup or if GPS had position and then lost
it, then the lamp will flash for 2 minutes while trying to acquire
position, then become failed (see 4c above).
