Yellow fog warnings are back over YVR this morning and they are already wreaking havoc on operations, with FlightAware showing 63 delays so far today. With similar conditions on Monday, there were 315 delays.
Dense fog continues to smother Metro Vancouver, with advisories still in effect around the airport and visibility dropping to near zero at times, forcing YVR back into low-visibility procedures after a weekend of weather-related disruption.
YVR works closely with meteorologists and NAV Canada to determine whether it's safe for planes to land or take off due to visibility on the runways.
But not all cancellations can be attributed to the poor visibility caused by the fog, YVR spokesperson Alyssa Smith told Vancouver Is Awesome.
"Ultimately, it is the decision of the pilot and NAV Canada on whether they're landing," Smith says.
When visibility worsens, flight schedules slow down in response. Smith likens the practice to leaving more space between cars in traffic during times of inclement weather. More space is required between aircraft to ensure safety before takeoff and during landing.
