Warnings, Cautions, & Notes

WARNING: The altitude calculated by 4XX/5XX GPS receivers is geometric
height above Mean Sea Level and could vary significantly from the altitude
displayed by pressure altimeters in aircraft. GPS altitude should never be used
for vertical navigation. Always use pressure altitude displayed by pressure
altimeters in the aircraft.

WARNING: The Jeppesen database used in the 4XX/5XX system must be
updated regularly in order to ensure that its information remains current.
Updates are released every 28 days. A database information packet is included
in the 4XX/5XX package. Pilots using an outdated database do so entirely
at their own risk.

WARNING: The basemap (land and water data) must not be used for
navigation, but rather only for non-navigational situational awareness. Any
basemap indication should be compared with other navigation sources.

WARNING: For safety reasons, 4XX/5XX operational procedures must be
learned on the ground.

WARNING: The United States government operates the Global Positioning
System and is solely responsible for its accuracy and maintenance. The GPS
system is subject to changes which could affect the accuracy and performance
of all GPS equipment. Portions of the Garmin 4XX/5XX units utilize GPS as a
precision electronic NAVigation AID (NAVAID). Therefore, as with all NAVAIDs,
information presented by the 4XX/5XX units can be misused or misinterpreted

and, therefore, become unsafe.

WARNING: The GTS 8XX interface is intended for advisory use only to aid
the pilot in visually acquiring traffic. No avoidance maneuvers should be
based solely upon TAS or TCAS traffic information. It is the responsibility of
the pilot in command to see and manuever to avoid traffic.

GTS 8XX Interface

GTS 8XX INTERFACE OVERVIEW

All information in this addendum pertains to the display and control of the Garmin
4XX/5XX Series units using a GTS 8XX interface. This addendum does not replace or
supercede the 4XX/5XX Pilot’s Guides. Refer to the 400/500 Series Display Interfaces
Pilot’s Guide Addendum (190-00140-10) when interfacing with non-Garmin
products

1.0 SYSTEM DESCRIPTION

The 4XX/5XX provides an optional display interface for the GTS 8XX Traffic
Advisory (TAS) and Traffic Collision Avoidance (TCAS I) Systems. The GTS 800
and GTS 820 are TAS systems, the GTS 850 is a TSO-Certified TCAS I system. The
GTS 8XX uses active interrogations of Mode A/C/S (GTS 820 and GTS 850 only) and
Mode A/C transponders to provide Traffic Advisories to the 4XX/5XX.

The GTS 8XX is an active traffic advisory system that operates as an aircraft-to­aircraft interrogation device. The GTS 8XX monitors the airspace surrounding an
aircraft, and advises the flight crew where to look for transponder-equipped aircraft that
may pose a collision threat. When the GTS 8XX receives replies to its interrrogations,
it computes the responding aircraft’s range, bearing, relative altitude, and closure rate.
The GTS 8XX then determines the advisory status of the target and sends the location
information and alert status to the 4XX/5XX for display.

The GTS 800 is capable of tracking up to 45 Mode A/C/S intruders. The
GTS 820/850 is capable of tracking up to 45 Mode A/C plus 30 Mode S intruders. Up
to 30 of the most threatening targets are displayed.

Pilots should be aware of TAS/TCAS system limitations. If an intruder transponder
does not respond to interrogations due to antenna shading or marginal transponder
performance, it will not be displayed, or display may be intermittent. Pilots should
remain vigilant for traffic at all times when using TAS/TCAS systems for non­transponder equipped airplanes or unresponsive airplanes.

1.1 TCAS I SURVEILLANCE VOLUME

Top and bottom mounted antennas allow an active surveillance range of up to
12 nm (GTS 800) or 40 nm (GTS 820/850) in the forward direction, and somewhat
reduced ranges to the sides and aft of own aircraft due to the directional interrogation
patterns. Interference limiting in GTS 820/850 units may automatically reduce range
in high density traffic areas.
