1. A method for monitoring thermal events in an aircraft engine compartment, the method comprising:

  • obtaining, at a thermal event detection system, first sensor data from a first sensor located within an engine compartment of an aircraft;

    determining a time series moving average based at least in part on a subset of the first sensor data, the time series moving average indicative of an average temperature rate-of-change of the engine compartment;

    determining a standard deviation of the time series moving average;

    detecting a trend of temperature rates-of-change that satisfy a rate-of-change criterion, the rate-of-change criterion based on a multiple of the standard deviation, wherein the temperature rates-of-change are based on temperatures of the engine compartment; and

    generating an alert in response to detecting the trend, the alert indicative of a thermal event associated with the engine compartment.
