I was reviewing the EDM data from some of my recent flights today and
spotted a strange anomaly in the EGT traces on one flight. I have
attached an MS Excel file with the raw data and two graphs of the data.
In chart 1 I circled the anomaly. In chart 2 I zoomed in on the
anomaly. This occurred about an hour into a 2.4 hr. cross-country in
dead smooth air on a CAVU day. I'm quite sure I did not do anything
with the engine controls or fuel system at this point in the flight. I
was cruising on autopilot enjoying the view. I don't remember noticing
anything unusual about the engine sounds or performance at any time
during the cruise.
Anybody have any idea what we're looking at here?
