G4 Twin Engine

The Insight GEM G4-Twin instrument is shown below. The GEM G4-Twin displays a twin-engine airplane's Exhaust Gas
Temperature (EGT), Cylinder Head Temperature (CHT) and Turbine Inlet Temperature (TIT), Carburetor Temperature
(CARB), Manifold Pressure (MAP), Tachometer (RPM), Oil Pressure (OIL), Fuel Flow (GPH), Bus Voltage (VDC) and
Outside Air Temperature (OAT) on a Liquid Crystal Display (LCD).
Each engine may be temporarily displayed similar to the G4-Single display by turning the page knob (PG) to the left or
right accordingly for leaning or engine diagnostic purposes.
The Insight Graphic Engine Monitor GEM 1200C (G4) Twin is capable of displaying the airplane's engine Exhaust Gas
Temperature (EGT), Cylinder Head Temperature (CHT) and Turbine Inlet Temperature (TIT), Carburetor Temperature
(CARB), Manifold Pressure (MAP), Tachometer (RPM), Oil Pressure (OIL), Fuel Flow (GPH), Bus Voltage (VDC) and
Outside Air Temperature (OAT) on a Liquid Crystal Display (LCD).
The G4 unit can be configured and installed as a single-engine (G4-001.) or twin-engine (G4-002) instrument.
The GEM G4-Single and GEM G4-Twin indicate temperatures that are displayed to one degree resolution in Fahrenheit
or Celsius degrees. The temperature unit is displayed in the lower portion of the display. The LCD dims automatically with
the intensity of ambient light.
The white, green and red colour-coded bar graph and digital values in the central and lower part of the display may be
used as primary indicators for EGT, CHT, and TIT. The cyan colour-coded values at the top of the display are supplemen-
tary, for reference only.
