1 GENERAL DESCRIPTION
1.1 Introduction
The G5 is an electronic instrument display capable of operating as a primary attitude indicator or rate-of-
turn indicator. This STC will approve the installation of the G5 as an attitude indicator or rate-of-turn
indicator in the existing instrument panel.
The Garmin G5 indicator can replace an existing vacuum attitude indicator. The G5 is designed to be
installed into a standard 3 1/8” instrument hole in place of the existing attitude indicator. The other
primary flight instruments remain in the current approved locations. The G5 cannot replace an existing
primary attitude indicator that has a Flight Director; however, if the existing attitude indicator is
interfaced to the autopilot and it does not include a Flight Director, that existing attitude indicator can be
moved to the rate-of-turn indicator location and the G5 installed as the primary attitude indicator.
Alternatively, for installations that do not install the G5 as a replacement primary attitude indicator, the
G5 can be installed as a second attitude indicator in place of the existing rate-of-turn indicator. If the
existing rate-of-turn indicator is interfaced with the autopilot, it cannot be replaced by a G5. Only one
G5 per airframe can be installed in the locations specified in this STC. It is the installer’s responsibility
to ensure the installation limitations are considered prior to modifying the aircraft..
NOTE
Throughout this document the term “rate-of-turn indicator” will be used and could be speaking to either a
turn coordinator or turn and bank indicator. Typically these instruments are used to cross-check the
attitude indicator and directional gyro for bank information. However, these instruments only provide
information that the aircraft is in a turn and whether the turn is at the standard rate (a standard rate turn is
3 degrees per second, or 2 minutes for a full 360-degree circle). They do not provide information on the
bank angle. Regardless of the specific instrument installed the G5 is capable of replacing either
configuration of a turn coordinator or turn and bank indicator.
The software versions and information in this document are subject to change without notice. Visit
www.Garmin.com and navigate to the Aviation Product/General Aviation/Indicators/G5 page for current
updates and supplemental information concerning operation of the G5 attitude indicator.

1.6 System Overview
1.6.1 Equipment Description
The G5 Electronic Flight Instrument is shown in Figure 1-1. The G5 is an electronic instrument display
operating as a standalone flight display. It features a bright, sunlight readable, 3.5-inch color display
which is sized to fit in a standard 3-1/8-inch instrument cutout. The G5 contains integrated attitude/air
data sensors that provide display of attitude and secondary display of air data information. The G5 has
battery backup and in the case of aircraft power loss will sustain G5 operation with up to 4 hours of
emergency power.
Figure 1-1 G5 Electronic Flight Instrument
1.6.1.1 Attitude
The G5 calculates aircraft attitude using information from its built-in inertial sensors. If the G5 senses that
the attitude solution is valid, but not yet within the internal accuracy limits, "ALIGNING" is displayed.
The G5 can align itself both while taxiing and during level flight.
The G5 will also use GPS and airspeed data to provide the most accurate attitude information. If none of
these additional sources of information are available, attitude calculations will still be valid but accuracy
may be slightly affected.
The G5 attitude functions are shown below:
•Pitch
•Roll
1.6.1.2 Turn Rate
The Turn Rate Indicator is located at the bottom of the display. A magenta Turn Rate Trend Vector shows
the current turn rate. A standard-rate turn (3 deg/sec) is shown on the indicator by the trend vector
stopping at the standard turn rate tick mark.

Page 10 of 53
1.6.1.3 Slip/skid
The Attitude Indicator displays slip/skid information as indicated by the location of the ball at the lower
center portion of the indicator.
1.6.1.4 GPS
The G5 requires GPS for attitude aiding. It contains an internal GPS receiver that can be connected to an
external antenna or optionally can use external GPS input if available.
As installed in this STC, the G5 receives the GPS via the following methods:
•Previously installed and approved GPS antenna (See Section 3.4.1)
•GTN 6XX/7XX series navigators (See section 1.6.2.1)
•GNS 4XXW/5XXW series navigators (See section 1.6.2.2)
Additionally, the G5 functions provided by the GPS are shown below:
•Ground Track
•Ground Speed (GS)
1.6.1.5 Air Data
The G5 unit is connected to the aircraft Pitot / Static system. See section 4.3.2 for details.
The G5 functions provided by the air data are shown below:
•Secondary Airspeed indicator
•Secondary Barometric altimeter
•Secondary Vertical speed
•Secondary Altimeter Barometric Setting
•Secondary Altimeter
•Secondary Altitude Display
•Selected altitude setting, bug and visual altitude alerting
•Secondary Vertical Speed Indicator
•Vspeed references
1.6.1.6 Standby Battery
The standby battery is required. The G5 has an externally mounted lithium – ion battery that sustains the
G5 flight display with up to 4 hours of emergency power.

1.6.2 G5 Interface Summary
The G5 Electronic Flight Instrument in this STC installation uses 14VDC or 28 VDC power, ground, RS-
232(2), and coax(1) connection for external mounted GPS antennas. The following list is a summary of
interfaces used by the G5.
•Aircraft Power and Ground
•Aircraft Pitot/Static
•GPS Coax connection (1)
•One RS-232 Input (2)
•Standby battery
(1) Used only in installations utilizing an external GPS antenna for GPS input to G5
(2) Used only in installations utilizing a GTN 6XX/7XX or GNS 4XXW/5XXW for GPS input to
G5
1.6.2.1 GTN 6XX/7XX Interface Summary
The G5 can utilize a RS-232 connection to an existing GTN 6XX/7XX when available to receive GPS
data. The RS-232 port used on the GTN 6XX/7XX needs to be configured to MAPMX Format 1. If an
existing connection is made to the required GTN RS-232 port, the G5 connection can be spliced into the
existing wiring at the GTN connector. Refer to Section 1.7.1.2.
1.6.2.2 GNS 4XXW/5XXW Interface Summary
The G5 can utilize a RS-232 connection to an existing GNS 4XXW/5XXW when available to receive
GPS data. The RS-232 port used on the GNS 4XXW/5XXW needs to be configured to MAPMX. If an
existing connection is made to the required GNS RS-232 port, the G5 connection can be spliced into the
existing wiring at the GNS connector. Refer to section 1.7.1.2.

1.7.1.1 Aircraft Power
The G5 operates using power from one 14 / 28 VDC input. Pin 8 (AIRCRAFT POWER 2) is not used as
a part of this STC.
NOTE
AIRCRAFT POWER 2 is for connecting to an alternate power source, such as on aircraft with
two electrical buses.
1.7.1.2 RS-232
The G5 has one RS-232 channel that may be used to output and/or receive GPS data from an
existing GTN 6XX/7XX or GNS 4XXW/5XXW. The G5 can utilize a RS-232 connection to an
existing GTN or GNS when available to receive GPS data instead of an external GPS antenna. The
RS-232 port used on the GTN or GNS needs to be configured to MAPMX Format 1. If an existing
connection is made to the required GTN RS-232 port, the G5 connection may be spliced into the
existing wiring at the GTN connector.
