Strategic Context Objectives Scope Approach ACARS 2000>2005 >2010 > P+S RADAR Departure Clearance Digital-ATIS Oceanic Clearance Classical Radar Mode S VDL2 Transfer of Control Clearances Microphone Check Downlink of Heading, Speed, Selected flight level Mode S VDL2 ADS-B Receiver Initial ADS-B services More CPDLC services More D-FIS services Airborne Separation Trajectory negotiation Autonomous Separation LINK 2000+ Mode S EHS CASCADE
4
CASCADE Objective Co-ordinate the implementation of the first ADS-B applications, more CPDLC services, D-FIS and other services; Making use of existing Mode S (1090 ES) and VDL2/ATN infrastructures where possible; To improve ATC sector productivity.

Scope - Stream 1 - 2008 Ground Surveillance Applications (ADS-B-out) In a radar environment In a non-radar environment On the airport surface ? Airborne derived data ? CPDLC, D-FIS and other Services Automatic-CPDLC Data link taxi Data link operational terminal information Pilot preferences downlink ? Marginal Investment
6
Scope - Stream 2 – 2011 Airborne Surveillance Applications (ADS-B-in) Situational awareness on the surface Airborne situational awareness Visual separation on approach Sequencing & Merging Major Investment CPDLC, D-FIS and other Services Graphical Trajectory Co-ordination ? Down stream clearance Flight Plan Consistency

ADS-B Scope “CASCADE is package 0.5 really”? Package 1: 12 applications, now 10 applications (merger) CASCADE: 8 applications, so Package 0.8 Real implementation: 1 application or Package 0.1 CASCADE is well and truly based on Package 1 for ADS-B.
10
Benefits ADS-B provides quality surveillance in a cost effective way; provides improved situational awareness in the cockpit; creates opportunities to delegate some ATC tasks to pilots; can provide situational awareness to airline operations centres. CPDLC reduces voice communication workload; limits the probability of misunderstandings; provides clear readable messages in a timely and unintrusive manner to pilots and controller; provides infrastructure of airline operations communications.

Economic Viability Initial Approach Operational Scope Simulations & Trials Requirements & Standards ECIP& Commitment Implementation Technical Feasibility Operational Need
12
Validation Approach Trials Characteristics: In an environment where the need exists Integrated in operational systems (air and ground)
13
Conclusion CASCADE Continues to exploit the potential of air ground data links; Re-uses the infrastructures put in place by other programmes; Keeps global implementation in mind. www.eurocontrol.int/cascade
