Abstract

An aircraft data management system which uses a reconfigurable algorithmic network to defines operations on a set of flight data along with interpreters to interpret the flight data in accordance with the reconfigurable algorithmic network. The reconfigurable algorithmic network accepts flight data from a variety of sources. The reconfigurable network defines functional relationships between and performs operations on the various flight data. The flight data sources and the relationships therebetween can be configured by the user. The aircraft data management system can be used with a variety of computers and operating systems without reprogramming while minimizing certification requirements.
