Abstract: A flight management system is modified so that it can deal with an unpredicted current event happening to an airplane based on non-standard maneuvers that have been carried out previously by other airplanes in similar circumstances. This allows the flight management system to adaptively or dynamically respond to a variety of flight path changes rather than rely solely on a set of fixed responses to predictable events during a flight. Specifically, the flight management system is configured to provide procedural recommendations to a flight crew in real time based on collaboratively filtered historical data such that the flight crew can make smarter choices while operating airplanes.
