CARE/ASAS Action
FALBALA Project
Dissemination Forum – 8th July 2004
Project conclusions and recommendations Thierry Arino (Sofréavia)

2. Synthesis – Applicability
ATSA-AIRB
ATSA-VSA
ASPA-S&M
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)
Compatible with Paris (in particular CDG) and London Gatwick current characteristics
Possibly compatible with Frankfurt current characteristics
Hardly compatible with London Heathrow current characteristics

3. Synthesis – Limitations
ATSA-AIRB
ATSA-VSA
ASPA-S&M
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
ATSA-AIRB
ATSA-VSA
ASPA-S&M
Safety expected mostly in remote areas
Significant safety improvements expected for VFR flights
Shared views between pilots and controllers: a challenge to quantify
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
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

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
