WEATHER
This document describes the Hazard Avoidance features
of the G1000 system. The main hazards to flight safety are
flying in or near weather, flying in close proximity to the
terrain and other flight traffic in close proximity.
The information contained in this section assumes un-
derstanding of the G1000 Multi Function Display.
This section is divided into groups as follows:
Weather
• GDL 69A (XM Weather)
• GWX 68
• WX 500 Stormscope
TAWS/Terrain
• Terrain Proximity
• TAWS (Terrain Awareness Warning System)
Traffic
• TIS (Traffic Information System)
• TAS (Traffic Advisory System)
7.1 WEATHER
CAUTION: GDL 69A NEXRAD weather data is to
be used for long-range planning purposes only.
Due to inherent delays and relative age of the
data that can be received, NEXRAD weather data
should not be used for short-range avoidance of
weather.
WARNING: Use of any GDL 69A Weather Product
for thunderstorm penetration is prohibited.
Weather information provided by the GDL 69
is approved only for weather avoidance, not

WEATHER
Weather Data Link Page Softkeys
The following softkeys perform the GDL 69A weather
functions on the Weather Data Link Page:
NEXRAD – press the NEXRAD softkey to show
NEXRAD weather and radar coverage information
(both are activated at the same time). Composite
data from all of the NEXRAD radar sites in the
United States is shown. This data is composed
of the maximum reflectivity from the individual
radar sweeps. The display of the information is
color-coded to indicate the weather level severity.
The update rate is every five minutes. Refer to the
legend for a description of the color code.
NOTE: WSR-88D weather surveillance radar
or NEXRAD (NEXt generation RADar) is a Dop-
pler radar system that has greatly improved
the detection of meteorological events such as
thunderstorms, tornadoes and hurricanes. An
extensive network of NEXRAD stations provides
almost complete radar coverage of the conti-
nental United States, Alaska and Hawaii. The
unobstructed range of each NEXRAD is 124
nautical miles.
NEXRAD Abnormalities
There are possible abnormalities regarding displayed
NEXRAD images. Some, but not all, of those include:
• Ground Clutter
• Strobes and spurious radar data
• Sun strobes, when the radar antenna points directly
at the sun
• Interference from buildings or mountains, which
may cause shadows
• Military aircraft deploy metallic dust which can
cause alterations in radar scans
NEXRAD Limitations
Certain limitations exist regarding the NEXRAD radar
displays. Some, but not all, are listed here for the crew’s
awareness:
• NEXRAD base reflectivity does not provide sufficient
information to determine cloud layers or precipita-
tion characteristics (hail vs. rain, etc).
• NEXRAD base reflectivity is sampled at the minimum
antenna elevation angle. An individual NEXRAD site
cannot depict high altitude storms at close ranges,
and has no information about storms directly over
the site.
• The resolution of displayed NEXRAD data is 2 kilo-
meters. Therefore, when zoomed in on the display,
each square block is 2 kilometers. The intensity
level reflected by the square will be the highest level
sampled within the 2 kilometer square area.
NEXRAD Intensity
Colors are used to identify the different NEXRAD echo
intensities (reflectivity) measured in dBZ (decibels of Z).
“Reflectivity” is the amount of transmitted power returned
to the radar receiver. Reflectivity (designated by the letter
Z) covers a wide range of signals (from very weak to very
strong). So, a more convenient number for calculations
and comparison, a decibel (or logarithmic) scale (dBZ), is
used. The dBZ values increase as the strength of the signal
returned to the radar increases.

ECHO TOP – press the ECHO TOP softkey to show
the location, elevation and direction the highest
radar echo. This may not indicate the top of a
storm or clouds, only the highest radar return
echo. The information is derived from NEXRAD
information and indicates the highest altitude at
which precipitation is falling. ECHO TOPS and
Radar coverage are activated at the same time.
ECHO TOPS are mutually exclusive from both
NEXRAD and CLOUD TOPS, that is, when ECHO
TOPS is activated, NEXRAD and CLOUD TOPS
are removed. Refer to the Legend for a descrip-
tion of the ECHO TOPS coding. The update rate
is every 7.5 minutes.
NOTE: Cloud Tops and Echo Tops use the same
color scaling to represent altitude. Turning on
both products at the same time is not allowed.
RADAR COVERAGE – The display of Radar Cover-
age is always active when NEXRAD and ECHO
TOPS are selected and indicates the currently
available NEXRAD Radar coverage and ECHO
TOPS areas by showing the area in a grayish-
purple color where information is not being
collected. Areas where radar capability exists, but
is not active or is off-line, will not be shown as
available. Areas where radar coverage is not avail-
able will be shown in grayish-purple. The update
rate is every five minutes.
CLD TOP – press the CLD TOP softkey to show
the cloud top altitude determined from satellite
imagery. Refer to the legend for a description of
the CLOUD TOPS color coding. The update rate
is every 15 minutes.
LTNG – pressing the LTNG softkey shows the loca-
tion of cloud-to-ground lightning strikes. The
update rate is every five minutes.
NOTE: Strike location falls within a 2 km region.
Therefore, the exact location of the strike is not
displayed.

CELL MOV – pressing the CELL MOV softkey
shows the storm cells identified by the ground-
based system. The movement is depicted by an
arrow. The update rate is every 12 minutes.
SIG/AIR – pressing the SIG/AIR softkey shows
SIGMET and AIRMET information to advise
the crew of potentially hazardous weather. The
advisory covers an area of at least 3,000 square
miles at any one time. The update rate is every 12
minutes.
NOTE: SIGMETs are broadcasted for hazardous
weather that is considered of extreme importance
to all aircraft. SIGMETs (acronym for “SIGnifi-
cant METeorological information”) warn of the
following weather hazards: severe icing, severe
and extreme turbulence, dust storms, sandstorms
or volcanic ash lowering visibility to less than 3
miles. A Convective SIGMET (WST) is issued for
hazardous convective weather (such as torna-
does, thunderstorms, hail) and covers severe or
greater turbulence, severe icing and low-level
wind shear. A localized SIGMET is a significant
weather condition occurring at a localized geo-
graphical position.
NOTE: AIRMETs are broadcast for weather
phenomena that potentially affect all aircraft.
AIRMET (acronym for “AIRman’s METeorological
information) gives valuable information about
the following conditions: moderate icing, mod-
erate turbulence, sustained winds 30 knots or
greater at the surface, widespread area with a
ceiling of less than 1,000 feet and/or visibility
less than 3 miles and extensive obscurement of
mountains. These are important to light aircraft,
that have limited flight capabilities due to lack
of equipment and/or instrumentation.

GDL 69 Troubleshooting
Although it is the responsibility of the facility that in-
stalled the GDL 69A to correct any hardware problems,
the crew can perform some quick troubleshooting steps
to find the possible cause of a failure.
First, ensure that the owner/operator of the aircraft in
which the GDL 69A is installed has subscribed to XM Ra-
dio and that it has been activated. Perform a quick check
of the circuit breakers to ensure the GDL 69A has power
applied. If a failure still exists, review the messages listed
in the table at the end of this section. The advisory mes-
sages may provide insight to a possible failure.
For troubleshooting purposes, the Status, Serial Num-
ber and Software Version numbers for the GDL 69A are
displayed in the LRU Information Window on the System
Status Page.
To select the System Status Page:
1. Turn the large FMS knob to select the AUX
Page Group.
2. Turn the small FMS knob to select the System
Status Page.

GWX 68 AIRBORNE WEATHER
RADAR
The GWX 68 Airborne Weather Radar System provides
weather detection and ground mapping capability. The
primary function of the weather radar system is to find
storms along the flight path. Weather detection gives the
crew the ability to recognize potentially dangerous thun-
derstorm cells.
The GWX 68 weather radar system also provides
ground mapping, giving the ability to distinguish land-
scape features and bodies of water.
Weather radar return strength is shown in six different
colors to show intensities of rainfall (black, green, yellow,
red, magenta, and white).
Table 7.1.2 shows six different colors associated with
the levels of rainfall or storm intensity.

TAWS/TERRAIN
TAWS
Garmin’s Terrain Awareness Warning System (TAWS)
satisfies TSO-C151b Class B requirements for certifica-
tion. Class B TAWS is required for all Part 91 aircraft
operations with 6 or more seats and for Part 135 turbine
aircraft operations with 6 to 9 passenger seats (FAR Parts
91.223, 135.154). Garmin TAWS greatly increases situ-
ational awareness and aids in reducing accidental Con-
trolled Flight Into Terrain (CFIT).
Figure 7.2.3 shows the Navigation Map Page with ter-
rain features.
In order to operate properly, the Garmin TAWS/Terrain
system requires a valid 3D GPS position solution and a
valid terrain/airport terrain/obstacle database.
CAUTION: It is always the ultimate responsibility
of the crew to navigate safely throughout the
course of flight. Garmin TAWS is designed to be
an aid to situational awareness, not to be relied
on as a primary source of terrain and obstacle
avoidance.

TAWS/TERRAIN
Forward Looking Terrain Avoidance
The Forward Looking Terrain Avoidance alert (FLTA)
is used by TAWS and is composed of two sub-functions:
Reduced Required Terrain Clearance (RTC) Avoidance
— Provides alerts when the aircraft flight path is above
terrain, yet is projected to come within minimum clear-
ance values shown in Table 7.2.2. When an RTC alert is
issued, a potential impact point is displayed on the TAWS/
TERRAIN Proximity Page.
Imminent Terrain Impact (ITI) Avoidance — Provides
alerts when the aircraft is below the elevation of a terrain
cell in the aircraft’s projected path. ITI alerts are accompa-
nied by a potential impact point displayed on the TAWS/
TERRAIN Proximity Page. The alert is given when the
projected vertical flight path is calculated to come within
minimum clearance altitudes in Table 7.2.2.
During the final approach phase of flight, RTC/ITI alerts
are automatically inhibited when the aircraft is below 200’
AGL while within 0.5 nm of the approach runway or is
below 125’ AGL while within 1 nm of the runway.

CAUTION: Estimated potential impact in
approximately 60 seconds after pop-up alert and
annunciation. For TAWS, RTC/ITI caution alerts
are accompanied by the aural message “Cau-
tion Terrain; Caution Terrain” OR “Terrain
Ahead; Terrain Ahead”.
WARNING: Estimated potential impact in
approximately 30 seconds after pop-up alert and
annunciation. For TAWS, RTC/ITI warning alerts
are accompanied by the aural message “Terrain,
Terrain; Pull Up, Pull Up” OR “Terrain Ahead,
Pull Up; Terrain Ahead, Pull Up”.

TAWS/TERRAIN
CAUTION: The above annunciation and pop-up
terrain alert are displayed during a PDA alert.
For TAWS, the PDA alert is accompanied by the
aural message “Too Low, Terrain”.
Premature Descent Alerting (PDA)
Garmin TAWS/TERRAIN issues a Premature Descent
alert when the system detects that the aircraft is signifi-
cantly below the normal approach path to a runway. The
PDA alert mode is functional only during descent to land.
There are three different scenarios to consider with PDA:
• No Approach Loaded — PDA alerting begins
when the aircraft is within 15 nm of the destina-
tion airport and ends when the aircraft is either
0.5 nm from the runway threshold OR is at an
altitude of 125’ AGL while within 1 nm of the
threshold. During the final descent, algorithms
will set a threshold for alerting based on speed,
distance and other parameters.
• Non-Precision Approach Loaded — PDA alert-
ing begins when FAF is the active waypoint AND
the aircraft is within 15 nm of the destination air-
port. Again, algorithms are used to set a threshold
for alerting based upon various parameters. PDA
alerting ends at 0.5 nm from the runway thresh-
old OR at an altitude of 125’ AGL while within 1
nm of the threshold.
• ILS Approach Loaded — PDA alerting begins
when FAF is the active waypoint AND the aircraft
is within 15 nm of the destination airport. Once
the aircraft intercepts the glideslope, PDA will
alert the crew if the aircraft descends 0.7 degrees
below the glideslope. PDA alerting ends 0.5 nm
from the runway threshold OR at an altitude of
125’ AGL while within 1 nm of the threshold.

TAWS Alerts
The following features are required to meet Class B re-
quirements for a TAWS system per TSO-C151b. TAWS
provides aural voice alerts along with regular display an-
nunciation. With each alert type shown is an accompany-
ing aural alert as well.
Excessive Descent Rate Alert (EDR)
The purpose of the Excessive Descent Rate alert is
to provide suitable alerts when the aircraft is deter-
mined to be closing (descending) upon terrain at an
excessive speed. Figure 7.2.7 shows the parameters
for the alert as defined by TSO-C151b.

TAWS/TERRAIN
Negative Climb Rate After Takeoff Alert
(NCR)
The purpose of the Negative Climb Rate After Takeoff
alert is to provide suitable alerts to the crew when the
system determines that the aircraft is losing altitude (clos-
ing upon terrain) after takeoff. The aural message “Don’t
Sink” is given for NCR alerts, accompanied by an annun-
ciation and a pop-up terrain alert on the display.
“Five-Hundred” Aural Alert
The purpose of the aural alert message “Five-hundred”
is to provide an advisory alert to the crew that the aircraft
is five-hundred feet above terrain. When the aircraft de-
scends within 500 feet of terrain, the aural message “Five-
hundred” is heard. There are no display annunciations or
pop-up alerts that accompany the aural message.
Alert Priority and Aural Alert Message
Summary
TSO-C151b requires the establishment of an internal
priority scheme for alerts. In this way, the more important
alerts will override lesser alerts. Table 7.2.3 shows the
alert priority level in the Garmin TAWS system and gives
a summary of the aural messages.
The aural alert is configurable for either male or female
voice. Different alert text phrases are available for several
alerts. Contact a Garmin authorized service center for fur-
ther information on configuring the alert system.
TAWS System Test
Garmin TAWS provides a manual test for the flight
crew. With this feature, the crew can verify proper opera-
tion of the aural and visual system annunciation.
To manually test the TAWS system:
1. At the TAWS Page, press MENU.
2. Select the “Test Terrain?” option.
3. Press ENT to confirm the selection.
An aural message is played giving the test results:
• “TAWS System Test, OK”, if the system passes the

TRAFFIC
7.3 TRAFFIC
TIS (TRAFFIC INFORMATION SYSTEM)
TIS is a system used for detecting and tracking
aircraft in the vicinity of your own aircraft. When ATC
radar interrogates aircraft transponders, the replies are
analyzed to determine range, bearing and the relative
altitude of the intruder. The traffic is then displayed to
the flight crew on the MFD.
CAUTION: TIS is unable to detect any intruding
aircraft without an operating transponder.
NOTE: Traffic Information Service (TIS) is not
available in all areas.
TRANSPONDER STATUS BAR
TIS surveillance data is up-linked by Air Traffic Con-
trol (ATC) radar through the GTX 33 Mode S Transpon-
der. The Transponder Status Bar displays the transponder
code, reply symbol and mode of operation on the Inset
Map (PFD) and the Navigation and Traffic Map Pages on
the MFD (refer to the MFD Pilot’s Guide).
In order to receive and display TIS traffic information,
the GTX 33 must not be in GND mode or STBY mode.
Figure 7.3.1 Transponder Status Bar
When traffic is displayed within the TIS volume, the
word TRAFFIC appears on the PFD. Figure 7.3.2 shows
the Traffic Annunciation on the PFD.
TRAFFIC MAP PAGES
The Traffic Map Page displays the following informa-
tion:
• Current aircraft location, surrounding TIS traffic,
and range marking rings.
• The current traffic mode (OPERATE, STANDBY).
• A traffic alert message (FAILED, DATA FAILED,
NO DATA, UNAVAILABLE).
• Traffic display banner (AGE 00:, TRFC COAST,
TA OFF SCALE, TRFC RMVD, TRFC FAIL, NO
TRFC DATA, TRFC UNAVAIL, TRAFFIC).
To select the Traffic Map Page:
1. Select the MAP group of pages. Turn the
small
FMS
knob to select the Traffic Map Page.
To display traffic on the Navigation Map
Page:
1. Press the
MAP
softkey.
2. Press the
TRAFFIC
softkey. Press the
TRAFFIC
softkey again to remove traffic.
NOTE: Traffic and terrain data can also be
displayed by using the ‘On/Off’ Navigation Map
Page option. See the Navigation Map Page setup
section for details.

TRAFFIC
TIS Symbology
TIS traffic is displayed on the Traffic Map Page simi-
larly to TCAS symbology. The main difference between
TIS and TCAS is the source of surveillance data. TCAS
uses an airborne interrogator with a half-second update
rate. TIS uses the terminal Mode S ground interrogator
and its Data Link to provide approximately a five-second
update rate. The range accuracy of TIS and TCAS is simi-
lar. Appendix E describes the Traffic Information Service
in detail.
The Traffic Advisory (TA) solid yellow circle indicates
that traffic meets the TA advisory criteria. The presence
of TA traffic beyond the selected display range is indicated
by one half of a yellow circle at the edge of the display.
The position of the half-symbol represents the bearing of
the traffic.
Altitude separation from your aircraft is displayed
above the target symbol if the traffic is above your alti-
tude or below the symbol if they are below. Altitude trend
is displayed as an up arrow (+500 ft/min), down arrow
(-500 ft/min) or no symbol if less than 500 ft/min rate in
either direction.
Traffic Ground Track is indicated on the Traffic Map
Page by a “Track Vector”. The track vector line is pro-
jected from the TA symbol at the angle of the TA relative
track.
Proximate traffic is shown as a white diamond with
a solid box inside. Other traffic is displayed as a hollow
white diamond. Proximate traffic and other traffic sym-
bols indicate that traffic is not yet considered a threat, so
no Traffic Advisory is generated.

Power-Up Test
The TIS interface performs an automatic test during
power-up. If the system passes the power-up test, the
standby screen is displayed on the Traffic Map Page. If
the system passes the power-up test while the aircraft is
airborne, traffic is immediately displayed on the Traffic
Page in the operating mode.
If the system fails the power up test, the ‘NO DATA’,
‘DATA FAILED’ or ‘FAILED’ message is displayed.
• The ‘FAILED’ message indicates the GTX 33 tran-
sponder has failed.
• The ‘DATA FAILED’ message indicates data is
being received from the GTX 33 but a failure was
detected in the data stream.
• The ‘NO DATA’ message indicates that data is not
being received from the GTX 33.
Contact a Garmin authorized service center for repair.

Changing the Map Range
To change the map range:
1. Turn the joystick clockwise to zoom out or turn
the joystick counter-clockwise to zoom in. Map
ranges are 2 nm, 6 nm and 12 nm.
NOTE: If the intruder aircraft is non-altitude
reporting only the range and bearing will be
displayed.
Operating Mode
Once the aircraft is airborne the system switches from
ground or standby mode to operating mode. The G1000
displays ‘OPERATE’ in the upper left hand corner of the
display and begins to display traffic on the Traffic or Map
Page.
The TIS Traffic Advisory (TA) should alert the crew
to look for intruding aircraft any time a yellow circle
traffic symbol appears and voice warning is announced.
Conduct a visual search for the intruder. Maintain
visual contact to ensure safe separation.
When the aircraft is on the ground the system switches
from operating mode to ground or standby mode. The
Traffic Map Page displays ‘GND’ or ‘STANDBY’.
• STANDBY – when the Traffic Map Page displays
‘STANDBY’ in the status box on the Traffic Map
Page, the TIS system is in standby mode and
cannot display traffic data.
• GND – when the Traffic Map Page displays ‘GND’
in the status box on the Traffic Map Page, the TIS
system does not display traffic data. The GTX 33
does not reply to Mode A or Mode C interroga-
tions but does send Mode S acquisition replies.
The ground mode is entered automatically. It is
not a crew selectable mode.
• OPERATE – when the Traffic Map Page displays
‘OPERATE’ in the status box on the Traffic Map
Page, the TIS system is operational and displays
traffic on the Traffic and Map Pages.
The crew can switch between the standby (STBY) and
operate (ON) modes to manually override automatic op-
eration using the page menu or softkeys.
To switch between operating modes:
1. Press the
MODE
softkey.
2. Press the
STBY
or
ON
softkey to switch between
modes. ‘STANDBY’ or ‘OPERATE’ is displayed
in the status box located in the upper left
corner of the Traffic Map Page, OR:
3. Press the
MENU
key. The page menu is
displayed with ‘Standby Mode’ or ‘Operate
Mode’ highlighted. Press the
ENT
key on the
desired selection.

TRAFFIC
TIS Audio Alert
A TIS audio alert is generated whenever the number of
TAs on the Traffic Map Page display increases. Limiting
audio to TAs only reduces the amount of nuisance alert-
ing due to proximate aircraft. For example, when the first
TA is displayed, the crew is alerted audibly. As long as a
single TA aircraft remains on the TIS display, no further
audio alert is generated. If a second TA aircraft appears on
the display, a new audio alert is sounded. If the number
of TAs on the TIS display decreases and then increases, a
new audio alert is sounded. The TIS audio alert is also
generated whenever TIS service becomes unavailable.
The volume of the audio alerts and the choice between
a male or female voice is configured during installation.
The following TIS audio alerts are available:
• “Traffic” - TIS traffic alert is received.
• “Traffic Not Available” - TIS service is not available
or out of range.
TIS Traffic Status
The MFD indicates the following TIS traffic status to
the flight crew.
Traffic Banner
• AGE - if traffic data is not refreshed within 6
seconds, an age indicator (i.e., ‘AGE 00:06’) is
displayed in the lower left corner of the display,
when displaying traffic. After another 6 seconds,
if data is still not received, the traffic is removed
from the display. The quality of displayed traffic
is reduced as the traffic data becomes stale.
• TRFC COAST - the ‘TRFC COAST’ (traffic coast-
ing) banner located above the AGE timer indicates
that displayed traffic is held even though the
data is stale. The quality of displayed traffic is
reduced.
• TRFC RMVD - the ‘TRFC RMVD’ banner indicates
that traffic has been removed from the display due
to the age of the data. Data is too old to “coast”
when the time period is 12-60 seconds from the
last receipt of a TIS message. The crew should be
aware that traffic may be present but not shown.
• TA OFF - the ‘TA OFF’ scale banner displayed in
the lower left corner of the display indicates that
a traffic advisory is outside the selected display
range. The traffic advisory off-range banner is
removed when the traffic advisory is within the
selected display range.
• TRAFFIC - on the PFD, when the system receives
a traffic advisory a flashing ‘TRAFFIC’ alert is
displayed in the upper left hand portion of the
display. The PFD inset map also automatically
displays traffic data.
CAUTION: TIS warns the crew with voice and
visual traffic advisories whenever it predicts an
intruder to be a threat. The display and advi-
sories are intended only for assistance in visu-
ally locating the traffic and lack the resolution
and coordination ability necessary for evasive
maneuvering. Always attempt to visually clear
the airspace before maneuvering your aircraft in
response to a TA. See Appendix E for detailed
TIS information.
