How it Works





A successful engine trend monitoring program is composed of three fundamental functions; Data Collection, Performance Plotting, and the Analysis.

Data Collection - Data must be accurately and regularly recorded during flight. This can be accomplished manually or by utilizing one of a variety of automatic data recorders.

Performance Plotting - Changes in Altitude, Outside Air Temperature, Indicated Airspeed, and different power settings are a few of the factors that can affect the engine's performance from day to day. To minimize the effects of these factors collected data needs to be processed through analytical software. The specialized analytical data processing software compares the captured data to a mathematical model and the results are plotted for analysis.

Analysis - An accurate and timely interpretation of the trend monitoring graphs is essential to the success of a trend monitoring program. Upon completion of the analysis, adverse results should be addressed and acted upon appropriately.
