The NAV CANADA Level of Service PolicyOpen a new window describes the requirements for the provision of air navigation services in Canada and in international airspace assigned to Canadian control. Periodic internal reviews examine operational and safety issues and customer needs to determine whether a formal change proposal is required. An aeronautical study is initiated when an internal review indicates that a change in the level of service may be appropriate.
Aeronautical studies evaluate changes to the air navigation system including the following:
changes to air traffic services,
changes to airspace classification and design, and
the introduction or termination of a service.
Aeronautical studies consider all relevant factors. These include traffic volume, mix and distribution throughout the day; weather; airport role; airport and airspace configuration; surface activity; and the efficiency requirements of operators using the service. Formal consultation with stakeholders is central to all aeronautical studies.
