Some days back our aircraft would not land and kept circling because of low-visibility (<1500m) and finally after circling for over 45 minutes, the pilot elected to return to DEL rather than land at the destination.
One of the runways RWY28 at the destination is configured for landings in low visibility upto 900m, but the crew said that becuase of wind direction RWY10 was our assigned rwy and so we couldnt use RWY28.
I understand landing "into the wind". But how critical is that? Is it that much of a problem landing with the wind? The aircraft was an Airbus A320.
