WEMSgen: A real-time weather modelling library for on-board trajectory optimisation and planning

• Time and Energy managed operations (TEMO) as a solution for environmentally friendly procedures in high-density TMAs • Importance of wind and real atmosphere accurate modeling to achieve very demanding time accuracies. • Smooth (continuous and twice differentiable) functions required in most numerical methodologies • WEMSgen successfully tested in human-in-the-loop real-time simulations • Flight trials with Cessna C550 scheduled in October 2015.
