AIXM, moving to electronic AIP and better
quality and availability of data
B0-105 Meteorological Information Supporting

The 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.
In Block 0 we improve overall
operations and continue to
enable Collaborative Decision
Making through improved
interfacilities communications
using standard information
formats

Optimum Capacity and Flexible Flights
B0-10
Improved Operations through Enhanced En-Route
Trajectories
Implementation of performance-based
navigation (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
B0-35
Improved Flow Performance through
Planning based on a Network-Wide view
Collaborative 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 to
avoid saturated areas
B0-85
Air 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
Preparatory Workshop for AN-Conf/12

Optimum Capacity and Flexible Flights
(cont’d)
B0-86
Improved access to Optimum Flight Levels
through Climb/Descent Procedures using ADSB
The 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.
B0-84
Initial Capability for Ground Surveillance
To provide an initial capability for lower cost ground
surveillance through new technologies such as ADSB OUT and wide area multilateration (MLAT)
systems. This capability can support various ATM
services, e.g. traffic information, search and rescue
and separation provision.
B0-101
ACAS Improvements
Implementation of ACAS with enhanced optional
features such as altitude capture laws reducing
nuisance alerts, linking to the autopilot for automatic
following of resolution advisories
B0-102
Increased Effectiveness of Ground Based Safety
Nets
Ground 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.
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

B0-05
Improved Flexibility and Efficiency in
Descent Profiles (CDOs)
Deployment of performance-based airspace
and arrival procedures that allow the
aircraft to fly their optimum aircraft profile
taking account of airspace and traffic
complexity with continuous descent
operations (CDOs)
B0-20
Improved Flexibility and Efficiency in
Departure Profiles (CCOs)
Deployment of departure procedures that
allow the aircraft to fly their optimum
aircraft profile taking account of airspace
and traffic complexity with continuous
climb operations (CCOs)
B0-40
Improved Safety and Efficiency through the
initial application of Data Link En-Route
Implementation of an initial set of data link
applications for surveillance and
communications in ATC
The use of procedurally based
Optimized Profile Climbs and
Descents as well as an initial
Data Link Capability helps to
establish a Block 0 capability for
improved operational
efficiencies

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
13
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
