Abstract
Various embodiments of the invention provide a function centric data system that reduces avionics system weight and power requirements. In some embodiments, the function centric data system is housed in a vibration resistant package. A variety of functions typically performed by other avionics systems are incorporated into the system, allowing centralize power and processing management, reducing weight and improving system reliability. In some embodiments, the function centric data system is configured to provide high rate data sampling, allowing ground stations to apply sophisticated failure prediction algorithms, reducing maintenance costs and mean time between flights. Embodiments include methods of wireless networking with automatic hand offs and adaptive multi-hop topologies to allow this data to be promptly transferred when the aircraft lands. Embodiments also include methods for data processing to predict imminent failures using Bayesian statistics and catastrophe prediction methods.
