  1. Managed Airspace or Free Flight by Steve Zerkowitz Assistant Director Infrastructure Europe IATA 1

  2. Results of R&D programmes like PHARE. • PHARE pre-dates the free flight concept • PHARE is firmly ground based • Advanced airborne capabilities are taken into account • Within its confines PHARE is as daring as the free flight concept itself • Proves what can be achieved by novel thinking and trust in computer support

  3. Will it will solve our problems • No single program can solve all problems • OCD recognises need for Managed Airspace • Managed Airspace will require advanced tools • PHARE should be right at home in Managed Airspace • Core area problems need to be addressed early on - PHARE is well positioned to do that

  4. Is it a threat to airlines’ autonomy? • Recognise OCD as necessary step beyond PHARE territory • Put PHARE in the context of Managed Airspace, do not claim that it is an overall solution • Refine PHARE results - CDM, SWIM, early free flight implementations • No threat to autonomy if done right!

  5. The concept of user-preferred trajectories • 3D versus 4D trajectories • The logistics of trajectory selection • User preferred trajectory = resource with dynamic, influences the bottom line • The appeal of users managing their own trajectories • Keep constraints to a minimum - each removed constraint is a step towards free flight!

  6. Separation assurance - ground based or air based? • See and avoid - the “good old” days • Growing speed and aircraft numbers, flight in all kinds of weather - ground surveillance and control becomes essential • Introduces inevitable inefficiencies (e.g. separation, trajectories) • ATC = some strategic and a lot of tactical • Inefficiencies can be reduced by modern ATC tools, but....

  7. Separation assurance ground based or air based? • Could we let the aircraft take care of most of the tactical aspects? • The electronic see and be seen and avoid environment • NASA and EUROCONTROL FREER shows it can be done • Where can decisions best be made?? • Not either or, but when and where one or the other. More R&D is needed.

  8. Practicalities of implementation • Implementation is only partly a technical challenge • Non-technical obstacles must also be addressed: • change of ATC culture • one airspace for ATM • rule making (ENPRM) • training • etc.

  9. Potential for cost saving. • Reduce delays, provide better trajectories • Savings must outweigh the costs of deployment and operation • Deployment decisions must be supported by appropriate cost-benefit analyses (deterministic or probabilistic) • The economic arguments against free flight - based on false premises and disregard time scales.

  10. Conclusions • Our view of the future = the OCD • No need to see PHARE as being in conflict with this, but • put in context (Managed Airspace) • continue R&D to explore the potential of free flight • PHARE has shown what can be achieved with an open minded approach

  11. Questions please!
