Engine Temperature Group - Garmin G1000:Piper Pilot's Manual

ENGINE INDICATION SYSTEM

ENGINE TEMPERATURE GROUP

Follow the engine manufacturer's recommended leaning procedures in the AFM.
NOTE:
Turbocharged Piper models are not equipped with the Lean Assist function.
NOTE:
The Temperature Group displays the head (CHT) and exhaust gas (EGT; displayed for normally-aspirated
aircraft only) temperatures in degrees Fahrenheit for each cylinder using bar graphs and digital readouts. For
turbocharged aircraft, Turbine Inlet Temperature (TIT) is shown on a sliding bar scale.
Cylinder Head Temperature
Normally-aspirated aircraft have an ASSIST Softkey for access of the Engine Leaning Assist Function.
When the ASSIST Softkey is pressed, the system automatically switches to the first peak obtained and
displays the temperature deviation from peak (∆PEAK) in degrees Fahrenheit beside the EGT readout for the
peaked cylinder. When a cylinder peaks, its number and readout are indicated in light blue and its peak is
represented by a light blue bar on the EGT bar graph.
Lean Assist continues to monitor this cylinder unless the temperature for the cylinder exceeds peak. If peak
is exceeded, Lean Assist is reset.
Selecting the Engine Leaning Assist Function (normally-aspirated aircraft):
From the Lean Display, press the ASSIST Softkey to identify the peak. The number and EGT readout for the
peaked cylinder are indicated in light blue and its deviation from peak temperature is displayed beside the EGT
Bar Graph.
