Monitoring & Abatement
As with our other environment programs, we carefully monitor noise using 20 noise monitoring terminals located throughout Metro Vancouver. This information is combined with radar flight track information provided by NAV CANADA to help us assess the noise environment around the airport and to determine how much noise is attributed to aircraft operations compared to other community noise sources.
The Noise Abatement Procedures (NAP) for YVR are published in the Canada Air Pilot (CAP 2) and are used by aircraft operators to minimize noise from operations. The NAP specifies departure/arrival procedures, preferential runway determination, altitude restrictions, and night restrictions. Under Canadian Aviation Regulation 602.105, air carriers in non-compliance with the NAP can be subject to enforcement action and fines issued by Transport Canada Civil Aviation Enforcement.
All Canadian International airports operate 24-hours per day, and each airport has restrictions and procedures to minimize noise at night. Some of the Noise Abatement Procedures at YVR that are specific to minimizing noise at night include:
- a prior approval requirement for jet operations between midnight and 7 a.m.
- a preferential runway system that attempts to keep both arriving and departing traffic over the Strait of Georgia, weather permitting
- early turn and special vectoring procedures for certain aircraft types to minimize over-flights of populated areas
- closure of the North Runway between 10 p.m. and 7 a.m. (except in the event of an emergency, maintenance, or snow)
