• Airspace design
• CNS technologies
• Traffic Flow Management
Why PBN? - Benefits
• Facilitates more efficient design of airspace and
procedures
• Improves safety, access, capacity, predictability,
and operational efficiency.
• Minimizes reliance on ground based navigation
routing and infrastructure
• Reduces aviation impact on the environment
– Less fuel burn and GHG emissions
– Less noise pollution

PBN in Canada

PBN in Canada
• May 2010 – PBN Framework document developed. Linked
to a Concept of Operations
• Sept 2010 – NAV CANADA received implementation
feedback from the ATOCC PBN Coordination Group
• October 2010 – Transport Canada committed to the
creation of a CARAC Working Group to review the intent
of PBN changes and the requirement for regulatory
structure
• October 2010 – NAV CANADA short term implementation
strategies provided to the aviation community through the
ATOCC / ANSNAC meetings
ATOCC PBN Coordination Group
•
A combined NAV CANADA and customer group plus
ADHOC industry experts coordinating activities and
milestones
– Scope of related issues is expanding
– NAV CANADA PBN Coordination Manager : Jeff Cochrane
• Goal is efficient and effective extraction of benefits from
latest technology and coordinated implementation of PBN

PBN Framework - Purpose
• To align NAV CANADA and our customer
expectations, priorities and objectives for the
implementation of PBN concepts in Canada over
the next 10 - 15 years
• To implement where feasible
– Coordinated with customer equipage plans

Implementation Strategy
Short Term (2010-15)
•
•
•
•
Continue with the Windsor/Toronto/Montreal Airspace Review
Implement RNP 10 in Edmonton FIR
Convert remaining CMNPS and RNPC airspace to PBN
Develop prioritized list of airports for PBN and commence terminal
redesigns based on PBN concepts
• Address AIS targets of opportunity
• Cyclic reviews
• Continue to implement 3rd party RNP designs
• Develop internal capability for RNP design
• Decommission non-essential ground based nav aids
• Educating NAV CANADA and the aviation community on PBN
• Explore viability of a Canadian or US test site for GBAS evaluation
12
Implementation Strategy
Medium Term (2015-20)
• Continue Terminal airspace reviews in accordance
with a prioritized list
• Re-assess and re-define the low level airspace
structure in concert with the surveillance strategy,
to incorporate PBN concepts
• Continue to expand the implementation of GNSS
procedures as customer equipage expands
12
Implementation Strategy
Long Term (2020 and beyond)
• Transition to a full PBN capability
• 4D RNP operations and a gate to gate flight
management environment
• Ground based navigation aid infrastructure is
reduced to the lowest possible
• Back up capability based on risk
assessment/vulnerability study
• Regulatory change is required

What is PBN?
• Transition from ground based sensor navigation to
area navigation (RNAV)
• Framework for defining navigation performance
requirements/ specifications in terms of:
– Accuracy, Integrity, Availability, Continuity, Functionality
• A toolbox of navigation specifications that can be
applied to a specific type of airspace to improve and
standardize operations
• Includes both RNAV and RNP as types of
specifications
14
RNAV and RNP
• Area Navigation or RNAV
– Enables aircraft to navigate point to point by using
onboard navigation equipment and updates from ground
based ( DME) , aircraft based (inertial units) or space
based ( GNSS satellite) navigation systems.
• Required Navigation Performance or RNP
– Same as RNAV except RNP aircraft have onboard
performance monitoring and alerting capability

Performance Based Navigation
RNAV Routes
RNAV SIDs
RNAV STARs
RNP Restricted approaches
RNAV approaches
Reduced reliance on ground based navigation aids

Customer Perspective
• Departure Phase
– Standard Instrument Departures for every departure runway that
quickly allows aircraft to join their route to destination
• En-route Phase
– Routes that are flexible based on that day’s operating conditions and
upper winds.
– If flexible routes are not possible then a network of RNAV and RNP
direct routes is preferred
• Arrival Phase
– Standard Arrivals that provide least track miles to the initial approach
fix, preferably with a CDA profile from top of descent
• Approach Phase
– A runway aligned with lateral and vertical guidance for every runway
end that terrain allows
