Synthesis Applicability
Applicable in various environments
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 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
CDTI use may lead to greater spacing
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
Impact on pilots workload depends on level of
automation Possible controllers
de-skilling Improper use can lead to degraded
situations
4
Synthesis Expected benefits
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
Safety expected mostly in remote
areas Significant safety improvements expected
for VFR flights Shared views between pilots and
controllers a challenge to quantify

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-SM 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
