NAV CANADA has
initiated a multi-year project to define a reduced network of ground-based
NAVAIDs across the country, supporting the transition to a more efficient and
cost-effective PBN-based air navigation service for our customers.
Using ADS-B, we have extended our air traffic surveillance to cover 4 million square kilometres of airspace, including 1.3 million square kilometers in the North Atlantic. NAV CANADA has entered into a joint venture with Iridium Communications, called Aireon, which is expanding ADS-B coverage to the entire globe, via low earth orbiting satellites.
With Performance-Based Navigation (PBN), we are using advanced onboard technologies to improve flight efficiency.
We are making changes to operations in the North Atlantic, the busiest oceanic airspace in the world.
In the fall of 2013 Canada will be converting to an ICAO-compliant significant meteorological information (SIGMET) and aviation weather advisory (AIRMET) bulletin format.
Multilateration (MLAT), which uses existing transponder technology to improve situational awareness, can be used to provide surveillance over a wide area, or surface surveillance at airports.
Instrument Landing Systems (ILS) are designed to provide aircraft with precision final approach guidance, offering a horizontal and vertical flight path to the runway.
