A simple add-on to existing radio
telephony systems would allow controllers to see which aircraft is talking to
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
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
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...
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)
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...
Data Link Operational Validation Simulation Completed
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
the new Vienna centre have sufficient capacity when it opens?
would be an appropriate transition strategy? These and other questions have
been tackled by the Future ATM Profile (FAP) team. More...
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.
Assigning a monetary value to aircraft noise
study made use of stated preference (SP) methodology and has allowed
monetary values to be assigned to aircraft noise annoyance.
Wake Vortex : Are Current Separation
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.
