It was more a question of, say I’m heading North and there’s an airport right ahead of me, so I think to myself “I’ll just land there” - how do I know which runway number is the one closest to my current heading?
Of course this is disregarding weather (I only fly in daylight and very ligh winds anyways in a ligh aircraft) and just wanting to know which is the one I can just descend to and land with minimum fuss for my course heading.
