In 2011, on stakeholder request a Network Severe Weather procedure project was established by the Network Manager in EUROCONTROL in order to improve the support provided to ATC centres in managing the risk to aircraft operations caused by severe convective weather. The development of an effective severe weather risk management and coordination procedure should take due account of local ATC centresâ capabilities, infrastructure, procedures and practices for severe weather impact management and how these elements could support the network severe weather procedure. Therefore a dedicated severe weather risk management survey was carried out in 2012. The survey scope covered the entire chain of severe weather impact and risk management starting with weather forecasting by meteorological offices, addressing pre-tactical management by FMPs and the Network Manager and concluding with the deployment of tactical measures by ATC and pilots.
