Collecting engine performance data and analyzing the data for condition monitoring of the aircraft health status has been a challenging and most sought after task for the airline operators. If the health status of the engine is in a good level, then the time before overhaul (TBO) can be lengthened. The present excel system is old and aged and takes lot of time to record the data and analyze. There was a need for simpler and more accurate way to analyze and manage the data. As part of the project course study, the authors have tried to develop a system for plotting engine data, which are collected during the flight. The data were limited to torque, exhaust temperature, compressor and turbine speed, and fuel flow only for Pratt and Whitney engine PT6A-41.
