  1. Project conclusions and recommendationsThierry Arino (Sofréavia) CARE/ASAS Action FALBALA Project Dissemination Forum – 8th July 2004

  2. Synthesis – Applicability Compatible with Paris (in particular CDG) and London Gatwick current characteristics Possibly compatible with Frankfurt current characteristics Hardly compatible with London Heathrow current characteristics Applicable in various environments Applicable in Frankfurt Unlikely to be applicable in Paris and London (where there is no use of visual separation on approach) Possibly applicable in other airports (e.g. Nice)

  3. Synthesis – Limitations Partial ADS-B out equipage Impact on pilots’ workload depends on design options Possible increase in controllers’ workload due to pilots’ queries CDTI requirements are ASAS applications dependent CDTI use may lead to greater spacing Impact on pilots’ workload depends on level of automation Possible controllers’ de-skilling Improper use can lead to degraded situations

  4. Synthesis – Expected benefits Increased controllers’ availability and more anticipation in sequence building Better stability of flows with more a/c getting optimal spacing values Better understanding of the situation and gain in anticipation by pilots Gain in capacity with staggered approaches to dependent parallel runways, but unclear benefits for single runways Additional safety from CDTI use (aid to visual acquisition and better ability to maintain own spacing) Possible reduction of pilots’ and controllers’ workload Safety expected mostly in remote areas Significant safety improvements expected for VFR flights Shared views between pilots and controllers: a challenge to quantify

  5. FALBALA results • Better understanding of the current situation for 3 major TMAs • Initial assessment of CDTI to support traffic situational awareness in core Europe • Objective radar data analysis complemented by operational feedback & experiment result analysis

  6. FALBALA conclusions • Airspace / airport characteristics and traffic demand must be considered when assessing applicability and benefits • Radar data analysis is of particular interest for such objectives • Operational benefits depend on the Airborne Surveillance application and the operational environment

  7. Recommendations for future work • Further benefit analysis should be performed • Enhancement of benefit evaluation process based on radar data extrapolation • ATSA-AIRB: Design studies for determining the appropriate traffic filtering • ATSA-VSA: Investigation of the US & Europe difference in operations • ASPA-S&M: Development of experiments for specific operational environments & design studies for determining the appropriate level of automation • Assessment of the required level of a/c equipage and cost analysis of avionics retrofit • Compared assessment of the most promising ASAS applications and alternative operational improvements
