"The tiedowns and lanes between hangars at my airport have really tight clearances. Got any tips for making sure I won't hit something with my wingtip?" —Oliver T.

“If you’re flying on a day that is sunny enough for your airplane to cast a shadow, look at the shadow of the wingtip near the object of your concern. Compare it to the shadow of the other wingtip, tail, or building to help judge. If they are coming together, there’s a good chance that you’re going to make contact. If you keep the shadows apart, you’re clear of the obstruction.
Of course, that doesn’t work if it’s cloudy or at night. During those conditions, turn on the nav lights and watch for close-up reflections to help you judge distance.
No matter what, if you’re unsure, shut down. Get out and look things over. Hitting a wingtip can be more than just swapping a little paint. It doesn’t take much impact force on a wingtip to push the wing aft and bend the rear wing spar. That’s an expensive mistake.”
