We missed our first approach into ZQN on Thu morning but got in on second attempt when they switched runways to approach from over the lake. Assume was a straight forward issue of minimum visibility as it was still zero vis out the window when they went around..
But on Sunday several inbounds missed their approaches with no visibility issues. Our inbound gave up after two misses and went home without us. In between we had a couple of Jetstar flights make it in.
Was it unusual crosswind or windshear?
