The goal of the product is to monitor and collect distress signals sent by aircrafts (in particular squawks 7500, 7600 and 7700). The system will download ADS-B data from FlightAware in a real-time manner and store filtered, normalized and aggregated records in a local data store. An API in a form of RESTful web services will be provided with a feed of current inflight emergencies, including their importance, geographic features and time trends, as well as a query interface for past events. In addition, the system will filter out false positives, either by using a predetermined set of rules supplied by aviation experts, or through a supervised learning model, based on historical data. The alerts related to current emergencies can be also actively fed to interested external parties (such as CAAs and ANSPs).
