Aircraft engine health monitoring system and method

A system and method are provided that monitors ground level ambient air in an airport ground environment while aircraft equipped with electric taxi drive systems and ground level visual monitoring assemblies are driven with the electric taxi drive systems during ground travel. Monitoring assemblies with detection elements having configurations similar to pitot tubes modified with a sensor array are provided to generate data about components in the ground level ambient air identified to adversely affect aircraft engine health. The detection elements may be cooperatively mounted with the ground level visual monitoring assemblies. Ambient air flow is directed into the detection elements to contact the sensor array during electric taxi drive system-powered ground travel. Real time data related to the identified components generated by the sensor array is processed and analyzed, engine health is monitored, and a predictive scheduled of engine maintenance may be developed from the analyzed real time data.
