Reducing vertical rate before levelling off should remove many unnecessary collision avoidance advisories

ICAO is developing a recommendation to pilots that when they are aware of another aircraft nearby, just prior to levelling off, that they reduce their vertical speed to 1500 feet per minute or less in the last 1000 feet before the level off. Recent Experimental Centre research has shown that this recommendation can reduce nuisance resolution advisories when approaching level off by at least 43%. A paper will be presented to the next meeting of the ICAO Airborne Surveillance Panel Working Group.

Increased use of conditional routes could help keep down delay in 2009

As part of the Dynamic Management of European Airspace Network (DMEAN) concept phase 2 validation, the Experimental Centre ran two sets of simulations late in 2005 and early in 2006:
  • Fast time traffic flow simulations concluded that increasing the use of conditional routes in Europe by a factor of 4 could keep the average delay per flight anticipated in 2009 down to about 1 minute
  • Real time demonstrations have shown how collaborative decision making processes applied between 3 hours and 1 hour before the real-time horizon could benefit overall airspace management.

Maturity of airborne surveillance applications assessed

The global maturity of seventeen applications based on Automatic Dependent Surveillance Broadcast (ADS-B), has been assessed by the ASAS Thematic Network 2 project. Relatively mature applications include ‘ATC surveillance in non-radar areas’, ‘In-trail procedure in non-radar oceanic airspace’, ‘Enhanced visual separation on approach’ and ‘Enhanced sequencing and merging’.

ACE platform enables multi-site Gate-to-Gate validation

Several real-time simulations, organised by AENA (Spain), ENAV (Italy), LFV (Sweden) and the EEC as part of the European Commission 5th FP GATE TO GATE Programme, were performed using an ACE (Avenue Compliant ESCAPE) platform provided by the Experimental Centre. These simulations concerned the evaluation, in different flight phases, of ATM solutions to the predicted increase of air traffic in Europe in the medium term.

Handling non-nominal situations with airborne spacing: similar to current operations

A series of small-scale controller experiments investigated non-nominal situations when using airborne spacing in the terminal area: mixed equipage, holding patterns and typical unexpected events (go-around, emergency, radio failure, spacing instructions not correctly executed). Handling mixed equipage and holding patterns was found to be feasible. Recovering from these unexpected events was found less difficult than anticipated and was evaluated as being similar to recovery in today’s operations.
