ADS-B SOLUTIONS

GPS engine and is designed to work with a WAAS GPS
navigator such as Garmin's GNS 530W and GNS 430W
or other approved navigators. Otherwise, the FDL978-XVR duplicates the features and functions of the
FDL-978-XVR/G, including the compatibility with panelmounted displays for the ADS-B In graphics and with
many tablet computers through the integral Wi-Fi module.
FreeFlight's Avail Performance Package includes
dual 1090 FDL-1090-TX Mode S/ES transponders, the
company's RANGR-RX/G 978 ADS-B receiver with
an internal WAAS GPS, integrated Wi-Fi, and a single
control head. These remote-mounted solutions provide
an all-in-one solution to equip with ADS-B In and Out for
the upcoming mandate.
A single one of the compact FDL-1090-TX 1090
ES transponder can serve as a solution for smaller
aircraft and for aircraft with crowded panels since the
transponder is a small, light, remote-mounted unit.
Control of the FDL-1090-TX is through a small panelmounted control head.
FreeFlight's Mode S 1090 ES transponders are
TSO and ETSO certified and STC'd for most aircraft.
Completing this system requires connection to a
certified WAAS GPS or other approved GNSS navigator.
FreeFlight also offers two ADS-B In-only packages
ideally suited to complement a 1090 ES-based ADS-B
Out solution or as a companion to a 978 ADS-B Outonly system.
The FDL-978-RX provides all the benefits of the FAA's
ADS-B In services, FIS-B and TIS-B, but no WAAS GPS.
This model can feed graphics to a panel-mounted display
and a tablet computer via its integral Wi-Fi.
The FDL-978-RX/G mirrors the FDL-978-XVR while
providing position data from its integral GPS engine. As
with the other 978 MHz devices, these are TSO certified
and STC-approved.
Garmin
Garmin's GDL 82 represents the company's
lowest-cost and simplest ADS-B Out solution: A small,
lightweight UAT datalink with an integral GPS receiver
and an installation process at a price of about $1,800.
Garmin engineers made installation simple and quick
by incorporating a patent-pending design with the GDL
82 installed in-line with the aircraft's existing transponder
antenna wiring to transmit the necessary ADS-B Out data.
Along with the integral WAAS GPS receiver required for
ADS-B compliance, Garmin includes the necessary GPS

antenna, providing further cost-savings for aircraft owners
without an existing WAAS GPS in their aircraft.
The GDL 82 employs Garmin's AutoSquawk
interrogation technology, which interfaces with most Mode
C general aviation transponders to synchronize the squawk
code and pressure altitude data from the transponder. This
allows the GDL 82 to work without installing a separate
dedicated UAT control panel and altitude encoder.
Garmin's GDL 88 and GDL 84 are the first dual-link UAT
solution for certified aircraft, including many popular makes
and models of helicopters, providing both a path to ADS-B
Out as well as the subscription-free weather and advanced
traffic display to the cockpit available from ADS-B In.
The biggest difference between these two GDL
models is the GDL 88 requires position data from an
approved source, such as one of Garmin's GTN allin-one nav/comm/GPS units; the GDL 84, conversely,
employs an integral WAAS GPS position source.
The company's patented AutoSquawk technology
synchronizes the transponder's squawk code and Ident
function with the GDL 88 or GDL 84, eliminating the need
for a dedicated UAT control head. Either of these units may
also be paired with Garmin's 1090 ES ADS-B Out solutions
to provide the operator with a complete ADS-B solution.
And with a Garmin Flight Stream wireless gateway
device installed, the operator can display subscriptionfree U.S. ADS-B weather and traffic on a tablet using the
Garmin Pilot, ForeFlight Mobile or FltPlan Go apps and
on Garmin aera 660/795/796 portables.
With its introduction of the GTX 345 series of Mode
S Extended Squitter transponders, Garmin delivered to
operators a one-box, one-swap solution that enables
owners and operators to meet both ADS-B Out
requirements with minimal expense, downtime and
disruption to their panels and at the same time provide
pilots with the full spectrum of weather and traffic
benefits from ADS-B In.
Designed to slide into the same 1.65-inch tall slot
as today's most-used transponders, the GTX 345 is
available with or without an integral WAAS GPS engine.
Without a GPS engine, the GTX 345 requires a
connection to an approved WAAS GPS navigator. But
Garmin also offers the option of equipping the GTX 345
with an integral WAAS GPS engine for a true one-box
solution. Garmin offers the GTX 345 in a remotemounted version compatible with the company's GTN
line of GPS/comm/nav systems and to work with the
G1000 integrated avionics system.
Garmin's GTX 3000 1090 ES transponder can be
coupled with the company's GDL 88 ADS-B datalink
receiver to fulfill global ADS-B requirements while
