International audience The North Atlantic (NAT) is the busiest oceanic airspace in the world. In its most part, Air Traffic Services (ATS) radar surveillance is unavailable and typical procedures have been established in order to ensure safe navigation. Aircraft wish to follow what is called the minimum-time route that depends on the position of the jet stream. Generally the preferred east-west trajectories lie further north than the west-east ones. So all USA-Europe flights, for instance, want to follow roughly the same route which is not possible. In order to accommodate as many flights as possible on, or close to, their minimum time tracks and to provide the best traffic control service, a system of tracks referred to as the Organized Track System (OTS) is constructed [1]. The OTS is set up on a diurnal basis is built according to the position of the jet stream. The USA-Europe network is located on the jet stream and the Europe-USA network avoid it. Each network consists of a set, typically 4 to 7, of parallel or nearly parallel tracks (see Figure 1).
