This "wire scan"
@Andy9 mentions for pre-flight steps is one I'll elaborate on, to express the importance.
I always try to look around the area I'm flying with binoculars for wires. You'll find wires in some of the most unsuspecting places, even across remote bays in Hawaii. Wires are everywhere. You would think being 150' in elevation would be above any wires, but not in Hawaii, where I found one small wire strung across high over
Honolua Bay in Maui. Fortunately I barely missed it while ascending vertically, straight up. I missed it by about 2'. I almost pooped my pants when it came into view. I was in disbelief what I was seeing over the ocean. But I had launched from 1/4mi away, and didn't take the binoculars to Maui.
Many folks here fly FPV BVLOS (this is technically illegal) because of the range and easy flight characteristics of the craft. If you ever do that, it's high risk flying over 15mph BVLOS (unless you know the area) under 250' AGL because most folks can't react fast enough for approaching wires going faster. There is a 200ms delay in the video you see on your screen, so you are closer to things than you actually see when flying forward. At 15mph that 200ms delay equals a little over 4'. If you are flying 30mph, that's about 9' closer to things than what you're seeing in the screen. Add on top of that your reaction time to stop. For most pilots that aren't expecting wires, that reaction can be 2 seconds, or another 44' (at 30mph). So the question is, can you see a wire that's 53' away (30mph), or 26' away (15mph). It really depends on wire thickness.
Once you realize all this, you start to fly slower when BVLOS, depending on your altitude. Sometimes it takes losing a craft to learn this specific situational awareness. I have a really good pair of 10X binoculars that are small enough to fit in my backpack. Although I don't always use them, I try to before launching at any new location. I look for wires as well as poles and towers. Sometimes I can see the pole or tower, but can't see the wires that I know they possess.
