Turn off the AI and and turn on the Live. then open “Flight Aware” or any similar real world flight tracking website and compare the traffic you see with what is displayed in the sim. There is usually a bit of delay between real time and sim but most of the traffic should match up. With the huge reduction in real world air traffic due to the pandemic it is possible that there are significant periods of quite at any airport.
I was at both Calgary International and Vancouver International over the last few days and can tell you that there is no where near the line of traffic we are all used to. A huge number of airliners just parked off the active areas of the airports. Looks apocalyptic.
