Improved thunderstorm weather information for pilots through ground and satellite based observing systems

Abstract

Within FLYSAFE, a European Commission funded project running from 2005 to 2009, a ground based thunderstorm weather information and management system has been developed which uses remote sensing information from radar, satellite and lightning detection systems. It has successfully been employed and demonstrated during flight trials carried out in summer 2009 over Central Europe. The aim of the paper is to demonstrate that the information provided by such a system could help pilots in gaining a better overview of the weather situation as compared to what can be provided by nowadays onboard systems. This in turn could help pilots in decision making, e.g. which route to take when passing through a thunderstorm line. For the study a number of aircraft accidents and incidents related to thunderstorm activity has been selected for demonstrating the usefulness of such a ground based weather information system. In each case, thunderstorm positions as detected by the ground based system are compared with actual aircraft positions and tracks where known. Finally, the possible up-link of the ground-based weather information to the cockpit is addressed by referring to ongoing and future activities in this direction
