Current American and European projects aim at transiting from ground-based systems to satellite-based systems. New technologies will allow to reduce significantly the present aircraft separation standards. As a consequence, the aircraft crossing the North Atlantic will be able to follow better routes, which will improve the air traffic situation by decreasing of flight durations and congestion in pre-oceanic continental airspace. In this paper an optimization model is introduced and a simple methodology to solve this problem is proposed that yields encouraging preliminary results. %G English %2 https://enac.hal.science/hal-00938895/document %2 https://enac.hal.science/hal-00938895/file/591.pdf %L hal-00938895 %U https://enac.hal.science/hal-00938895 %~ ENAC %~ INSMI %~ MAIAA %~ MAIAA-OPTIM %~ TDS-MACS %~ OPTIM
