THE BLACK TRIANGLES depicted on this

Garmin G1000 multifunction display represent traffic targets received via ADS-B In.
The white numbers in black rectangles
denote the altitude difference in hundreds
of feet. This airplane is sitting on the
ground, so all the displayed traffic is at
higher altitudes-as much as 9,300 feet
higher.

enjoy integrated ADS-B In data? No. L3
Aviation Products offers the Lynx NGT9000, a single-box 1090ES transponder
that includes dual-frequency ADS-B In,
Wi-Fi to your tablet, and a color touchscreen display. It also has an integral
WAAS GPS to serve as the ADS-B position source. One option is Active Traffic,
a more refined alerting technology that
gives earlier notice of a potential conflict,
and continues working below 500 feet
agl-where many traffic conflicts occur.
Another option is an embedded Terrain
Awareness Warning System (eTAWS),
which provides aural and visual alerting

QUESTION TO ASK BEFORE YOU EQUIP

Where do you fly? If you fly above 18,000 feet msl or internationally, choose a 1090ES extended squitter
transponder as your ADS-B Out solution-this datalink is required above FL 180 and is the international
standard.
Do you have a WAAS GPS navigator, or a non-WAAS GPS that can be upgraded to WAAS? If so, it can
serve as your ADS-B position source, possibly saving a few dollars on your installation. If not, have you
ever wished you had LNAV/VNAV GPS approach capabilities? While upgrading your nav will add to the
total cost, this could be a great time to do so.
What kind of transponder do you have? Transponders are still required after 2020, so if your transponder is an old Narco or Bendix/King KT-76A-the smart money might be on replacing it with an ADS-B
transponder.
Are you interested in ASD-B In (FIS-B weather and TIS-B traffic)? If so, and you want to display the
data on a multifunction display or other certified cockpit screen, make certain you choose compatible
ADS-B hardware-not everything is. Likewise, if you want to display ADS-B In data on a tablet, research
your options. Apps are not compatible with all the available hardware-or tablet types (iPad and Android,
for example).
"ADS-B: Questions to Ask" (November 2016 AOPA Pilot) discusses these questions in more detail.

of terrain hazards and obstructions such
as antennas; TerrainVision depicts terrain
but does not alert.
Aircraft owners considering an NGT9000 might need to rearrange their radio
stacks. To efficiently utilize the color
touchscreen, the transponder should
be near the top of the stack-just below
the audio panel. In most airplanes the
transponder is buried at the bottom of
the stack, or-worse-on the right side
of the panel.
How much will an all-in, integrated
ADS-B solution cost? Certainly, more
than a bare-bones, meet-the-mandate
ADS-B Out installation. And the cost will
be greatly influenced by what's already in
your panel-for example, if you already
have a Garmin WAAS GPS navigator, you
might be able to replace that old analog
transponder with a GTX 345 for not much
more than $6,000 installed-just a couple
thousand more than an ADS-B Out-only
installation.
The important thing to remember is
that you don't have to buy a whole new
panel to truly benefit from ADS-B technology. But if you're doing that anyway,
there's no better time to add ADS-B to the
work order.
