4th FAA - EUROCONTROL AP6Technical Interchange Meeting

(TIM -4)

Ground-based Decision Support for Conflict

Detection and Resolution

2

Intro : TIM Background

• FAA - EUROCONTROL Co-operation on Research & Development

• Action Plan 6 : Decision Support Tools

• Technical Interchange Meetings :– TIM 1 A/G data applications Washington 1998– TIM 2 Surface Management Braunschweig ‘98– TIM 3 Lessons learned HMI Toulouse 1999– TIM 4 Conflict Probe Memphis 1999

ATC - Conflict Probe History general

• Conflict detection and resolution is the essence of Air Traffic Control ICAO : ATC will prevent collisions while expediting

and maintaining an orderly flow of air traffic

• Automation of ATC conflict detection : – the holy grail – the product of alchemists– the philosophers’ stone– reality

4

ATC - Conflict Probe History human based

• Elementary air based conflict detection and resolution: See and be seen

• First step of ground based conflict detection: ATC by Dead Reckoning

• Safety provided by Procedural control conflict detection and resolution

• Capacity provided by Radar control conflict detection and resolution

ATC - Conflict Probe HistoryAutomation (1)

Automation of Conflict detection has been experimented since the introduction of data processing in ATC :– on the basis of flight plan data and procedural

separation criteria

(an application of automated conflict detection based on flight plan data and procedural separation criteria is presented on the next slides)

ATC - Conflict Probe History :Automation (2)

Automation of Conflict detection has been experimented since the introduction of data processing in ATC :– on the basis of flight plan data and procedural

separation criteria

– on the basis of surveillance updates to flight plan data

– on the basis of trajectory prediction with tactical flight plan updates and conformance monitoring

ATC - Conflict Probe Where are we to-day

• US application : Memphis URET• European application : Amsterdam ACOD• European research :

– France : ERATO

– Germany : VAFORIT

– Spain : SACTA/FOCUCS

– UK : FACTS

– EUROCONTROL : • Automated support to ATC programme

• PHARE demonstration

• evolution of controller roles

10

ATC - Conflict Probe Future Perspective (1)

• Conflict Detection and Resolution dependencies :– accuracy of trajectory prediction

– technical performance

– reliability

– tactical data updates

– human factors

• The real thing for perfection :– exchange of air/ground data

ATC - Conflict Probe Future Perspective (2)

The EUROCONTROL organisation is in the process of defining its ATC/DP strategy as an element of the ATM

strategy for 2000+ :

2005 2010 2015
