NAV CANADA will be conducting flight checks on the Instrument Landing Systems (ILS) for Runway 26R LOC on July 4, 2017. Please note that this date is subject to change due to operational reasons or poor weather conditions.
The ILS provides critical navigational information to aircraft on approach to assist with landings. Maintenance and flight checks are required to ensure the ILS meets stringent certification standards prescribed by Transport Canada. Flight checks involve a specially equipped Canadian Regional Jet (CRJ-200) operated by NAV CANADA that will fly unusual patterns and simulated approaches to the runway.
In the past, the flight checks were performed during the daytime at YVR. However, due to increasing volume of air traffic in the airspace around Vancouver, performing the flight checks during the daytime has become more challenging and has a higher level of risk due to a number of smaller aircraft operating in the area from other aerodromes. This has often resulted in extending the duration of the check as the aircraft is asked to hold at low altitudes until the airspace is clear to continue the work.
As a result, the upcoming flight checks will be conducted in the early morning hours, with an estimated start time of 4:30 AM, to help enhance the level of safety and to shorten the duration of the check. Because the traffic volume in the airspace is much lower during this time of the day, it also provides increased opportunities to mitigate noise by shortening the flying time of the aircraft, using reduced engine power settings, and using modified flight circuit patterns to minimize overflights of populated areas whenever possible.
The duration of flight checks each day is expected to last up to 2 hours, and the north runway may be used for some aircraft during this time depending on operational requirements.
Further efforts will likely result in a reduction in flight times associated with future ILS checks, resulting in less noise and environmental impacts.
