1. An in-flight risk management system comprising:
a microphone installed in a cockpit of an aircraft;
one or more in-flight risk management (IRM) computers in communication with the microphone; and
one or more data stores in communication with the one or more IRM computers and storing instructions that, when executed, cause the one or more IRM computers to perform operations comprising:
continuously monitoring audio data comprising cockpit conversations received from the microphone;
detecting, from the audio data, that a particular command litany has been initiated by processing, in real-time using a trained machine learning module, the audio data;
in response to detecting that the particular command litany has been initiated, determining, from the audio data and within the command litany, a command-response timing and a command-response accuracy, the command-response timing comprising a timing between responses and commands spoken during the particular command litany, and the command-response accuracy comprising an accuracy of the responses and commands spoken during the particular command litany; and
generating, based on the command-response timing and the command-response accuracy, one or more fatigue indicator values for each flight crew member involved in the particular command litany.
