For aircraft operators
looking to satisfy the ADS-B “Out” equipage rules as quickly and
cost-effectively as possible, the Garmin GTX 335 ES transponder offers the
ideal one-box, one-swap solution. It’s optionally available with a built-in
WAAS GPS position source – so everything needed to meet compliance standards
for a certified ADS-B “Out” solution can be provided with this simple
all-in-one package installation.
The Inside Track to ADS-B “Out”
With more fielded
ADS-B solutions than any other brand in the industry, Garmin is committed to
making the transition to NextGen airspace as simple and straightforward as
possible. The IFR-certified GTX 335 is a prime example. It looks and operates
like a standard Mode S transponder. It fits in the same 1.65-inch high slot in
your avionics stack. It boasts a digital display, a pressure altitude readout,
and dedicated pushbuttons numbered 0-9 for quick and easy squawk code entry.
Plus, it’s an all solid-state design, which makes for lower power consumption
and enhanced reliability, compared to earlier-generation transponder
technology. What’s more, the addition of 1090 MHz ADS-B “Out” transmission
capability (using precise GPS-referenced positioning information) enables the
GTX 335 to automatically output more accurate, and more useful, traffic
surveillance data to ATC – including aircraft flight ID, position, altitude,
velocity, climb/descent, and heading information. Conventional Mode S and Mode
C transponders can only broadcast altitude and squawk code – which means they
require ground-based radar to correlate and identify the aircraft’s position on
the controller’s radar screen.
Enhanced Traffic Surveillance
Using1090 MHz extended
squitter ADS-B “Out” transmission, the Garmin GTX 335 improves upon the
existing transponder query system while working seamlessly with existing ATC
protocols. The ADS-B reports provide ground controllers with considerably
faster updates than traditional radar. And by simultaneously broadcasting this
information to ADS-B “In” display-equipped pilots, it enables them to
essentially see the same traffic picture for their location that ATC is
watching on the ground.
Leverage Your Existing Avionics
Designed to interface
with a wide range of avionics, the GTX 335 enables operators to leverage their
existing cockpit equipment to meet ADS-B “Out” requirements with a minimum of cost,
downtime and disruption to their panels. The ES transponder’s 1090 MHz ADS-B
“Out” signal meets worldwide requirements for flight at any altitude. And, as a
size-conforming replacement for many existing Mode S or Mode C transponders,
the GTX 335 makes it easy to plug in the NextGen capability you need to the
avionics layout you already have. For even more flexibility, optional remote
mount GTX versions are available for compatibility with the GTN™ 750/650
series of touchscreen GPS/Comm/Nav systems, as well as select Garmin G1000® integrated
flight deck systems – all of which provide
built-in remote transponder code selection and control.
Altitude Encoding Made Simple
In addition to its
WAAS-enabled position reporting capabilities, the GTX 335R can also be paired
with an optional Garmin altitude encoder to satisfy data transmission
requirements for IFR. As opposed to other transponders with altitude encoding
built in, the Garmin altitude encoder mounts separately on the install rack.
So, should the transponder ever require removal, there’s no need for the static
line to be disconnected. Which, in turn, eliminates the need for a follow-on
leak check, and thus helps minimize ongoing service costs.
An Easier Path to NextGen
For decades Garmin has
led in the development and deployment of ADS-B technology. Today, the Garmin
GTX 335 series is being FAA approved for installation on hundreds of today’s
most popular aircraft makes and models. It’s clear that with the all-in-one GTX
335 solution, Garmin is working to make your transition to ADS-B operations a
simple matter of swapping out your transponder.
