The most recent incident, now in "Spotters Corner" wasn't my concern.
All I was trying to say was, that on a 3 or 4, with all engines set up to do the same thing, it is most likely that the EEC data from each will respond with similar trends. So as well as the EEC monitoring each engine, a comparison of trends will provide the first indication that any one data point is moving at a faster rate than the average of the same data points from the remaining engines.
Its not the absolute values we should be interested in, but the rate of change and direction of deviation from the mean - that's the first indication of "trouble up at mill".
