Abstract

A computerised method is provided for monitoring the status of an aircraft. The method comprises sending, from an output module of an aircraft monitoring system, a reporting more report data signal response and monitoring, at an input module of the aircraft monitoring system, for received data signal to the aircraft monitoring system. This sets a contract with the aircraft that may be used to monitor for unexpected behaviour or non-compliance with the contract terms. The method further comprises determining, at a processor of the aircraft monitoring system, if one or more alert criteria have been satisfied by the received data signal responses and generating, at an alerting module of the aircraft monitoring system, an alert based on the determination.
