Global Readiness Checklist

• Each Module is evaluated for its readiness• If any component is not found to be ready it moves to a future

Block for implementation• Those Modules that are not specifically ready at a Block

release are noted as “dates of readiness”

B0-80Improved Airport Operations through Airport CDMAirport operational improvements through the way operational partners at airports work together

B0-15Improved Traffic Flow through Runway Sequencing (AMAN/DMAN)MeteringTime-based metering to sequence departing and arriving flights

The combined Block 0 Modules reduce fuel consumption and

noise by improving arrival efficiencies and improving

information sharing

Preparatory Workshop for AN-Conf/12 9

Globally Interoperable Systems and DataB0-25Increased Interoperability, Efficiency andCapacity through Ground-GroundIntegrationSupports the coordination of ground-grounddata communication between ATSU based on ATS Inter-facility Data Communication (AIDC) defined by ICO Document 9694

B0-30Service Improvement through DigitalAeronautical Information ManagementInitial introduction of digital processing andmanagement of information, by theimplementation of AIS/AIM making use ofAIXM, moving to electronic AIP and betterquality and availability of data

In Block 0 we improve overall operations and continue to

enable Collaborative Decision Making through improved

interfacilities communications using standard information

formats

B0-105 Meteorological Information Supporting Enhanced Operational Efficiency & SafetyThe dynamic integration of ATM and MET information is expected to provide timely meteorological information to enable real-time identification, increased predictability and deployment of operationally effective ATM solutions to accommodate changing conditions, as well as facilitate tactical avoidance of hazardous meteorological conditions.

Optimum Capacity and Flexible Flights

Using procedural concepts (e.g. RNP, FUA, etc.) and Air Traffic Situational

Awareness - combined with enhanced planning tools and information

sharing, the enroute phase of flight supports additional capacity and

flexibility using the Modules of Block 0

B0-10Improved Operations through Enhanced En-Route TrajectoriesImplementation of performance-basednavigation (PBN concept) and flex tracking to avoid significant weather and to offer greater fuel efficiency, flexible use of airspace (FUA) through special activity airspace allocation, airspace planning and time-based metering, and collaborative decision-making (CDM) for en-route airspace with increased information exchange among ATM stakeholders

B0-35Improved Flow Performance throughPlanning based on a Network-Wide viewCollaborative ATFM measure to regulate peak flows involving departure slots, managed rate of entry into a given piece of airspace for traffic along a certain axis, requested time at a waypoint or an FIR/sector boundary along the flight, use of miles-in-trail to smooth flows along a certain traffic axis and re-routing of traffic toavoid saturated areas

B0-85Air Traffic Situational Awareness (ATSA)This module comprises two ATSA (Air Traffic Situational Awareness) applications which will enhance safety and efficiency by providing pilots with the means to achieve quicker visual acquisition of targets: AIRB (Enhanced Traffic Situational Awareness

during Flight Operations) VSA (Enhanced Visual Separation on

Approach).

Using procedural concepts (e.g. RNP, FUA, etc.) and Air Traffic Situational Awareness -

combined with enhanced planning tools and information sharing, the enroute phase

of flight supports additional capacity and flexibility using the Modules of Block 0

B0-86Improved access to Optimum Flight Levels through Climb/Descent Procedures using ADS-BThe aim of this module is to prevent flights to be trapped at an unsatisfactory altitude for a prolonged period of time. The In Trail Procedure (ITP) uses ADS-B based separation minima to enable an aircraft to climb or descend through the altitude of other aircraft when the requirements of procedural separation cannot be met.

B0-101ACAS ImprovementsImplementation of ACAS with enhanced optional features such as altitude capture laws reducing nuisance alerts, linking to the autopilot for automatic following of resolution advisories

B0-102Increased Effectiveness of Ground Based Safety NetsGround monitoring of the operational environment during flight to provide timely alerts of risks to flight safety. In this case, short-term conflict alert, area proximity warnings and minimum safe altitude warnings are proposed.

B0-84Initial Capability for Ground SurveillanceTo provide an initial capability for lower cost ground surveillance through new technologies such as ADS-B OUT and wide area multilateration (MLAT) systems. This capability can support various ATM services, e.g. traffic information, search and rescue and separation provision.

Challenges - How to Get There?

• It is all about managing risk

• Block 0 risks are minimum– Global Readiness Checklist is complete– The Modules are well understood and supported

• But risks do exist– States may not be capable of ensuring successful deployment of Block 0– If Block 0 is not implemented as a foundation, certain functionalities may

not be available as enablers for future blocks– We must Identify and resolve policies necessary to enable the future

blocks now

Preparatory Workshop for AN-Conf/12

14

Implementation – The Time is Now

• The Modules of Block 0 are ready for implementation today– Standards are ready – The Infrastructure is available– Avionics are ready – Ground Automation is ready– Procedures and Operational Approvals are in place

• Establishing the foundation for the future is now• Care was taken to ensure that regional

implementation of the Blocks or the Modules are well described and ready for implementation

Summary and Conclusions

• The “Aviation System Block Upgrades” initiative is the best approach to reach our goals: – Enables global interoperability (which is our goal)– Develops clear solutions (block upgrades)– Establishes a transition plan (it’s a well thought out way for

going forward)– Support the development of a Global CNS/AIM and

avionics roadmaps

• Block 0 is ready for deployment

Points to Remember

• Block 0 leverages on capabilities within our grasp today– Takes advantage of existing avionics– Ready for implementation

• Priorities in Block 0: PBN, CCO & CDO– ICAO held PBN Symposium in October 2012:– Download documentation at:

www.icao.int/Meetings/PBN-Symposium

• All WPs for Block 0 Modules available on Conference Website– www.icao.int/anconf12
