The Research of a Model-Based Derivative Alarm Identification Method for Civil Aircraft

With the widely application of new product and new technology, the cross-linking relationship between civil aircraft systems are becoming more and more complex. When one system fails internally, other systems may also come to failures due to the cross-linking relationship between the systems, eventually triggering multiple crew alarms in the cockpit and causing trouble to the crew. Therefore, how to accurately identify the triggered alarm in the cockpit has become a difficulty in the alarm design of civil aircraft crews. This article proposes a model-based derived alarm identification method for civil aircraft, which can accurately identify alarms in the triggering state in the cockpit, help designers quickly analyze and design cross-system derived alarms, and avoid multiple alarms being triggered at the same time, which may cause consequences to the crew.
