After 10 Years
• Safety
– IFR to IFR LOS from 1.36 (per 100,000) in 1997 to 0.77 in
2006
• Service
– Increased collaboration, reduced delays and fuel burn
– Customers savings of $100 million annually
• Service Charges
– 6 % increase since 1999, 14 percentage points below inflation
– 4% reduction effective August 1, 2007
• ANS Non-Operational Costs
– Additional $100 million in annual savings
• Technology Innovations
– $1 billion invested in safety, service, efficiency

Enhancing Safety and
Efficiency
• Customers’ Goals
– Safety
– Schedule
– Efficiency
• (fuel savings = reduced emissions)
– Value
5
Enhancing Safety and
Efficiency
• Global focus on industry with concerns
about:
– Rising fuel costs
– Energy supply
– Safety and security
– Greenhouse gas emissions
• Innovation and optimization by all
industry players required to address
these concerns
• NAV CANADA will do its part
6
Enhancing Safety and
Efficiency
• Identify/explore new and viable methods to
reduce greenhouse gas emissions and
improve flight efficiency

–
Optimum route and altitude
Continuous climb to cruise
Continuous idle descent to approach
Lowest possible approach minima
Minimum ground delay
Increased airspace capacity
Increased airport capacity
7
Enhancing Safety and
Efficiency
• Example: Investigate effects of noise
abatement procedures on:
– capacity,
– arrival and departure rates,
– fuel burn and emission production
• Coordinated investigation into ‘potential’
with stakeholders
8
Optimizing ATM
• Improve safety and efficiency by:
– Increased application of RNAV with
performance
– Airspace and airport capacity
enhancements
– Complementary aircraft and ANS
technology
9
Area Navigation (RNAV)
• Initiatives
– RNAV Routes
• Random Route Trials
– RNAV STARS (Standard Instrument
Arrivals)
– RNAV SIDS (Standard Instrument
Departures)
– RNAV Approaches (WAAS and RNP)

Northern Organized Track
Structure (OTS)
• Implemented January
2007
• 2,100 flights per year
• Saves 1-3 min/flight
• Fuel savings of ~315
metric tonnes/year
• CO2 reduction of
approximately 1,000
metric tonnes/year
11
Airspace Optimization
• Expanded Northern
surveillance coverage in
2004
• RVSM implemented
throughout Canada in
2005
• Expanded Northern
Direct Controller – Pilot
Communications
(DCPC) in progress*

Multilateration
• Tracks and identifies all
transponder equipped
targets in all weather
conditions
• Improvements to
capacity, efficiency and
safety
• Initial installation at
Vancouver Harbour; Fort
St. John

Enhancing Capacity
Visual Aircraft Spacing Tool
(VAST)
GHOP

• Fewer delays experienced
by users
• Adaptable as a spacing
tool for:

Converging Runway
Application
Converging Runway Display Aid (CRDA)
Application
– converging runways
– dependent and independent
parallel approaches
– single runway operations
• Increases in capacity
– up to 30% in Calgary
16
Increasing Efficiency
Extended Computer Display
System (EXCDS)
• Advanced tower,
terminal, airport and
en route coordination
system
• Automates flight data
transactions
• Part of suite of ATM
products designed to
improve efficiency
17
Looking Ahead
• Expansion of northern surveillance and
VHF communications
• Expansion of GPS-based (RNAV) en
route and approach procedures
• Increased use of Polar Routes;
Northern OTS
• ADS-B and Multilateration
implementation
