An on-aircraft recording device includes an interface that receives APU usage data from an aircraft auxiliary power unit (APU) independently of a flight data recorder and data acquisition unit. The on-aircraft recording device can be communicatively coupled (e.g., wirelessly) to a data acquisition service (DAS) system that communicates APU ground-run usage data received from a plurality of on-ground aircraft to a data management center (DMC) utilizing a plurality of unique callback identifiers. The DMC can include a DMC APU ground-run data structure for storing APU ground-run usage data and a processor configured to receive APU ground-run usage data for a plurality of on-ground aircraft, record, in the DMC APU ground-run data structure, the APU ground-run usage data for the plurality of on-ground aircraft, detect if the APU ground-run usage data satisfies an APU usage threshold, and electronically communicate, via a communication network, an alert indicating potentially excessive APU use.
