Installation Planning
Plan the location of the GEM display such that it is not positioned near any source of high
electrical current and is easily visible by the pilot. If the GEM is to be used as a primary engine
instrument it is essential to locate it high in the instrument panel and within the pilot's normal
instrument scan.
The GEM's wiring harnesses should be positioned away from sources of high energy, such as
ignition harnesses, P-leads, alternator wiring and high frequency radio wiring and antennas.
Some thought about the steps needed may save hours of installation time and trouble-shooting.
Steps to a successful installation
1. Check the GEM's STC Approved Model List for aircraft model eligibility.
2. Check the engines temperature limits (CHT/TIT) as specified in the engine Type Certificate,
aircraft Type Certificate or Flight Manual. GEM's are normally supplied with 460 degrees
(CHT) and 1650 degrees (TIT) Fahrenheit redlines but others are available. GEM instruments
with other redlines are indicated by a suffix in brackets after the instrument Part Number.
Eg. P/N 610C-001 - indicates normal Redlines
P/N 610C-001(X) - indicates other Redlines
Consult with Insight for available temperature limits.
3. Select which new G-series GEM model is to be installed. High-performance aircraft
strongly benefit from the advanced features of the G3 or G4 models. The G1 model is
designed for small aircraft with low-horsepower engines, it is NOT recommended for complex
or high-performance aircraft
a) Single engine aircraft may have any one of G1, G2, G3 or G4 models installed.
b) Twin engine aircraft normally have a pair of G3 or G4-001 models installed where
sufficient instrument panel space is available, or a G4-002 (Twin) instrument may be
installed otherwise.
4. Review the features and requirements of the selected GEM model to ensure compatibility
with existing and planned aircraft equipment.
5. Identify whether or not the installation is an upgrade from a legacy GEM system or a first-
time GEM installation. In the case of an upgrade, see the "Upgrade Installation" section.
6. GEM installation kits contain much of what is required for installation except for the
materials listed in the "Tools and Materials Required" section. The installer must supply all the
materials listed in the "Tools and Materials Required" section.
