The Netherlands Armed Forces operate several types of helicopters, such as Chinook, Apache, Cougar, Lynx, and in the future NH90 helicopters. To gain insight on the impact of helicopter missions on the life of the helicopter's airframe, helicopter's engine, and other vehicle systems, large amounts of flight data, health data and usage data of the helicopters have to be collected, stored and analyzed. This paper presents the advantages of using an XML Database for storing and querying the collected heterogeneous helicopter signal data.

The Royal Netherlands Air Force (RNLAF) operates several weapon systems, such as Chinook and Apache helicopters, F-16 fighters and C-130 Hercules transport aircrafts. For these weapon systems the Dutch National Aerospace Laboratory NLR performs several loads and usage monitoring programs. For these programs masses of flight and administrative data are collected and stored in multiple, heterogeneous weapon system specific databases. This paper presents the design, usage and benefits of a data integration layer that provides a uniform view on all weapon system databases.
