ILS Flight Checks: February 12, 2017

NAV CANADA aircraft will perform flight checks on Instrument Landing Systems at YVR on February 12

NAV CANADA will be conducting flight checks on the Instrument Landing System (ILS) for Runways 08L on Sunday, February 12. Please note that the date is subject to change due to operational reasons or poor weather conditions. The north runway may be used for departures during the flight checks. 

The ILS provides critical navigational information to aircraft on approach to assist with landings. Routine maintenance and flight checks of the ILS are a regulatory requirement to ensure the system meets stringent certification standards prescribed by Transport Canada. Flight checks involve a specially equipped Canadian Regional Jet (CRJ-200) that carries navigational equipment necessary to test and certify that the ILS equipment is accurately calibrated, functioning properly and safe for use.

The flight checks are conducted by NAV CANADA, who is responsible for the safe co-ordination and the efficient movement of aircraft in Canadian domestic airspace and international airspace assigned to Canadian control. NAV CANADA operates the specially equipped CRJ-200 and flies approaches to the airport from several angles, elevations and speeds. These flight profiles are unusual and are not seen during normal daily operation. This type of activity is safe and is required for the continued safe operation of aircraft at YVR.

The duration of a flight check depends on the type of maintenance done to the system, but normally lasts between 2-4 hours.
