Flight plan management in a distributed air traffic control system

The authors explore how large-scale replication can enhance the availability of data in a loosely coupled distributed system. The concern is with air traffic control systems that are geographically distributed and impose strict constraints of availability. In this framework, a replication system providing a weak consistency of data is proposed. The specific properties of flight plan data are studied, and possible replication strategies are discussed. The authors´ approach, which is characterized by a split between the propagation function and the end-user service, is then presented
