Key messages

  • Digitalisation can play an active role in optimising ATM, increasing fuel efficiency and limiting non-CO2 effects such as stable contrails in ice-supersaturated regions.
  • The aviation sector is very complex, with many stakeholders involved (e.g. airlines, network managers) who often have conflicting needs and requirements. This will mean that the various trade-offs should be optimised (e.g. noise vs. emissions, capacity vs. emissions) and that the need to identify priorities is particularly important.
  • The indicators used to assess the operational performance of ATM are not always comprehensive in assessing the environmental impacts of inefficiencies in flight planning and selected trajectories. There is room for further improvement.
  • Policy will play a key role in reaping the benefits of optimising ATM through digital technology.
