The AIS service (Aeronautical Information Service) is an operational service for Air Traffic Control and the functionality via availability and data integrity is one of the critical factors for the AIS Centre. Particularly the ATC operation is highly depended from IT-Systems, technical infrastructure and there availability. The analysis shows the relevant standard requirements of availability and long-term maintenance to an AIS-System and their statistical analysis. The goal of statistical analysis is to investigate the observed parameter like availability and robustness of functionality and services. In the paper research of maintenance parameter based on the statistical analysis, and results for further operational use are discussed. The statistical analysis was used for planning process of the product management. The analysis of different incident types and their characteristics based on the collected statistical maintenance data over operational period from 2001 to 2006 was performed. The results of statistical investigation will be used for a more stabile forecasting of operational use of the system and get statistical information for the future trend and migration of a new system platform. The statistical analysis is shown the relevant requirements of ATC maintenance for long-term used IT Systems.
