GENERAL DESCRIPTION

1.1 Introduction

The G5 is an electronic instrument display capable of operating as a primary attitude indicator,
backup attitude indicator with primary rate-of-turn indicator, DG or HSI. This STC approves
the installation of the G5(s) in the existing instrument panel.
In the attitude application, the Garmin G5 indicator can replace an existing vacuum attitude
indicator or rate-of-turn indicator. The G5 can also replace existing vacuum driven DGs or
existing HSI's, either standalone or in combination with a G5 attitude display.
When installed as a DG/HSI, the G5 can interface with third party autopilots using the GAD
29B.
The G5 is designed to be installed into a standard 3 1/8" instrument hole in place of the
existing indicators mentioned previously. 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. The G5 can only 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.
