Lean Assist
The ASSIST softkey activates Lean Assist Mode. This
pilot aid identifies for each engine the peak EGT of the
first cylinder whose temperature falls.
The peaked cylinder is selected and a cyan line appears
above the cylinder' s bar to indicate the reference EGT
peak. A readout showing the temperature deviation from
peak (∆PEAK °C) is displayed above the EGT Bar Graph.
If the temperature of the peaked cylinder exceeds the peak
value, the peak value is not updated while in Lean Assist
Mode.
Monitoring of a cylinder continues until the ASSIST
softkey is pressed again, which disables Lean Assist Mode
and remove the cyan peak line from the bar graph and the
∆PEAK Readout.
