The Long Term Planning Phase begins years before the day of operation, terminates six months before day of operation with the first publications of the shared business trajectories and is followed by the Medium Term Planning Phase. The objective of the Long Term Planning Phase is to design the infrastructure both at airspace and airports levels to optimise the use of these resources, taking into account Airspace Users' preferences. The sizing of ATM resources is driven by the Key Performance Areas (KPAs) and the Key Performance Indicators (KPIs) defined by the SESAR performance framework; the reference capacity of ATM resources; traffic forecasts; and airspace requirements expressed by Civil and Military users.
