Normalize / Standard View
To toggle between Standard and the Normalize views, hold the LF
button for three seconds until the NRM icon toggles on or off. Note:
Normalize cannot be activated while in Lean Find mode.
• Standard view (when the NRM icon is not lighted): the EGT
represent absolute temperature. The top of the columns indicate
absolute temperature relative to the adjacent range mark temperature
scale. A maximum height column depicts the temperature at the top
of the range mark scale (or more), while no column represents the
temperature at bottom of the range mark scale(or less). The Standard
view permits comparison of EGTs across all cylinders.
• Normalize view (when the NRM icon is lighted): the EGT represent
the difference in temperature from the mid-point of the range mark
scale. When you change to the Normalize view, all EGT columns are
initially normalized to the mid-point for deviation trend analysis.
Any changes are shown as an increase or decrease relative to the
mid-point, thus giving an instantaneous indication that an EGT has
deviated. You normally use normalize in level cruise, but it is also
useful during steady state run-ups. Note: A common misapplication
is to be in the Normalize view and then change power setting. This
causes all columns to go off scale, high or low. Select Standard view
before changing power or altitude.
Temperature Units (°F or °C)
The EDM can display engine temps in either °F or °C (Fahrenheit or
Celsius). In Primary configurations, this is set to the same units as the
configuration the aircraft was originally certified to.
