I have two airports, one with a runway of 5-23 and another of 10-28. Which way must the wind be blowing for 23 to be active at one airport and 10 at the other?
Generally speaking a wind out of the southeast would fit the situation. Basically a wind direction anywhere between 150-180 degrees would provide you with about 50-80 degrees of crosswind on either runway 23 or 10.
