Monitoring is Showing that ACAS and RVSM are Working Satisfactorily Together
The number and type of resolution advisories (RAs) observed in RVSM is similar to that seen from FL250 to FL290. More...

ACAS Safety Bulletin Number 3: Wrong Reaction to “Adjust Vertical Speed” RAs

Safety Learning at Maastricht
A consistent incident trend at the Maastricht's Upper Area Control Centre (MUAC) was detected and analysed in a collaborative effort between MUAC's Safety and Incident Investigation personnel, and the SAFLEARN project at the EEC. Changes in the new MUAC interface and in controller working practices have been proposed to halt the trend and avoid a possible ATM accident. More...

Collaborative Decision-Making Pilot Study Starts at Heathrow Airport
More accurate estimates of arrival and departure times will improve stand and gate planning which will in turn reduce congestion on taxiways. More...

Conference Papers
Several papers on airborne spacing were presented at Guidance, Navigation and Control, and a wide range of innovative papers were presented at the Digital Avionics Systems Conference. See also the Executive Report on the 5th FAA/Eurocontrol ATM R&D Seminar in Budapest (ATM 2003 website),.

Phase 2 of ADS-B Validation Testbed (AVT) Demonstrated
The development of AVT Phase 2 has been completed and the platform has been successfully demonstrated in Arlanda, Sweden, and at the EEC, Brétigny, with live ADS-B and radar air traffic. The platform will be used from 2004 to validate "Package 1" ground surveillance applications in multiple locations in Europe. More...

Second Data Link Operational Validation Simulation Completed Successfully
The DOVE 2 real time simulation studied the operational impact of advanced data link services such as COTRAC (Common Trajectory Co-ordination) and DYNAV (Dynamic Route Availability). The experiment demonstrated that these data link services could lead to new working methods, improved interfaces, reduced controller workload and better air/ground integration. More...

Will the new Vienna centre have sufficient capacity when it opens?
What would be an appropriate transition strategy? These and other questions have been tackled by the Future ATM Profile (FAP) team. More...

Air Transport and Environmental Economics
With 13% of carbon dioxide emissions in the transport sector, aviation is the transport mode whose share of emissions has grown the fastest over the past decade. After having reached the limits of regulation by standards, what will come next? Emissions trading? Fuel taxes? Environmental charges? We review the stakes, the current situation and some possible options. More…

Assigning a monetary value to aircraft noise annoyance
The 5A pilot study made use of stated preference (SP) methodology and has allowed monetary values to be assigned to aircraft noise annoyance. More...

Wake Vortex : Are Current Separation Standards Appropriate?
An integrated wake vortex safety and capacity system used in combination with modified wake vortex safety regulations is expected to enhance runway capacity, while maintaining safety. More...
