Initial STC Covers Some 580 Different Aircraft Makes And
Models
Garmin International announced Wednesday that the FAA has
granted an approved model list supplemental type certificate
(AML-STC) for the Garmin’s TAS and TCAS I traffic systems,
the GTS 800, GTS 820 and GTS 850. The initial AML-STC includes
approximately 580 different aircraft makes and models and Garmin
expects to add additional aircraft to the AML-STC in 2010. This
announcement follows the technical standards order (TSO)
authorization that Garmin received in November.
The GTS 800 traffic series combines active and passive
surveillance data to pinpoint specific traffic threats. The systems
use Garmin’s patent-pending CLEAR CAS technology and
correlates automatic dependent surveillance broadcast (ADS-B) with
radar targets to provide pilots with the most accurate picture of
the sky.
“The GTS traffic series is one of several aviation
products designed to be compatible with the NextGen system. It can
track up to 60 targets at a time, identify the flight path of
specific aircraft, and give spoken audio alerts in an ATC-like
format so that pilots are able to react immediately to their
surrounding traffic situation,” said Gary Kelley,
Garmin’s vice president of marketing.
There are three distinct system configurations for the GTS
series, and each model creates a 360-degree zone of detection
around the aircraft so that pilots can see and identify targets in
their airspace that may pose a collision hazard. The GTS 800 TAS is
a lower-cost system offering 40 watts of transmit power and a range
of up to 12 nautical miles. The GTS 820 TAS delivers 250 watts of
transmit power and up to 40 nautical miles of interrogation range.
The GTS 850 TCAS I satisfies all TCAS I collision avoidance
criteria for higher-capability turboprops and jets. It features the
same 250 watt performance as the GTS 820, and also meets the
FAA’s TCAS I certification criteria. The GTS 820 and GTS 850
are installed in conjunction with a Garmin Mode S transponder.
All GTS series products include
Garmin’s new CLEAR CAS (Correlated Location Enhanced ADS-B
Receiver Collision Avoidance System) technology, a hybrid system
that provides real-time information totally independent of
radar-based air traffic control. CLEAR CAS combines active and
passive surveillance data, including 1090 MHz Extended Squitter
ADS-B data (ADS-B Out required). The system provides enhanced
information that allows select displays to be updated to show
flight ID, altitude, velocity, and direction of target
aircraft.
Traffic information from the GTS series is displayed on the map
page or traffic page of Garmin’s panel mount aviation
products and integrated display systems using TAS/TCAS symbology.
Additional traffic symbology can be displayed on Garmin’s
synthetic vision technology (SVT) equipped PFDs. When the GTS
product receives replies to its interrogations, it computes the
responding aircraft’s range, bearing, relative altitude, and
closure rate. Then, it enhances location data with data received
from ADS-B Out equipped targets, plots the traffic location,
predicts collision threats, and depicts the information on the
traffic display. The system also includes expanded audio traffic
alerts in an ATC-like format. For example, “Traffic; Eleven
o’clock; High; Less than one mile.”
The GTS series also offers flexible antenna configurations that
ensure optimum system performance for specific types of aircraft.
Customers with fixed gear airplanes and rotorcraft may choose a
single directional quadrapole antenna on top of the aircraft, with
or without a bottom mounted omnidirectional antenna. For optimal
performance on retractable gear aircraft, customers may select a
top-and-bottom dual directional antenna configuration.
The GTS 800, 820 and 850 are available immediately for an
expected list price starting at $9,995, $19,995, and $24,995,
respectively.
