G SERIES PILOT'S GUIDE .
The EGT values are displayed as vertical white bar graphs (one per cylinder). Digital EGT values for each cylinder may
be indicated by white four-digit numeric displays below the bar graph. CHT is indicated by a vertical green bar graph (one
per cylinder) while the CHT value is within normal CHT operating range, or by a red vertical bar graph if the CH [value
exceeds the maximum CHT limit. A horizontal red line indicates the maximum allowable CHT. Digital CHT values are
indicated by 3-digit numeric displays below the bar graphs. The digital CHT values are show in green while within normal
operating range or red if the CHT limit is exceeded. Turbine Inlet Temperature (of a turbocharger-equipped engine) is
displayed by a green vertical bar graph and digital value on the right-hand side of the display while the TIT value is within
normal operating range, or by a red bar graph and digital display if the TIT value exceeds the maximum TIT limit. A red
horizontal line displays the maximum allowable TIT.
The GEM G4 instrument senses temperatures through thermocouple-type probes. The instrument is powered typically
from the avionics bus and protected by a dedicated, trip-free, resettabte 1A circuit breaker. GEM instruments automatically
accommodate both 14 and 28 VDC electrical systems.
LIMITATIONS
The Insight Engine Monitor GEM 1200C – G4-Single and G4-Twin instruments may replace any eligible aircraft Cylin-
der Head Temperature (CHT) indicator or Exhaust Gas Temperature (EGT) or Turbine Inlet Temperature (TIT) indicator.
Single-engine airplanes utilize the G4-Single instrument, while twin-engine airplanes utilize the G4-Twin.
The Manifold Pressure (MAP), Carburetor Temperature (CARB), Tachometer (RPM), Oil Pressure(01l), Fuel Flow (GPH),
Bus Voltage (VDC) and Outside Air Temperature (OAT) indications at the top of the display are supplementary information,
for reference only.
