First Claim
1. A method of monitoring engine starting system performance in a gas turbine engine, said method comprising:
- sensing data related to the operation and performance of said gas turbine engine;
continuously sampling selected data parameters from said sensed data during an engine start sequence;
evaluating said data parameters to determine whether specific criteria have been met; and
capturing selected engine starting system performance data when said specific criteria are met.

Abstract
A method and system for monitoring engine starting system performance in a gas turbine engine using a plurality of sensors to sense data related to the operation and performance of the gas turbine engine. Selected data parameters from the sensed data are continuously sampled during an engine start sequence. The data parameters are then evaluated to determine whether predetermined sets of criteria have been met. Selected engine starting system performance data and data sampling times are captured when each of the sets of criteria are met. The captured engine starting system performance data are normalized and then compared to a parametric baseline for the gas turbine engine.
