Re: Power lines

Here is the place I had to go under the cables.
I was coming the opposite direction, low and slow, and no way to go over them, or make a 180.
Below the power lines was another cable you cannot see in the picture, ended up flying between the power lines and the lower cable

Re: Power lines

VBA. Very Bad Array.

There is a really hidden dangerous altitude where this kind of wires or cell towers reside. In both cases, lower is often safer. Where there is room below or around, we can see the obstacles easier and have better assurance of energy maneuverability throughout.

The trick to the emergency energy management turn is early anticipation of the need to turn. That gives us room to pitch up trading airspeed for altitude, turn in less horizontal space because of slower speed, and regain airspeed energy as the nose goes down more and more as the bank steepens.

The real problem is that this technique will not be there unless learned at altitude and practiced regularly. Most of my students were bound for Ag, but even they may have wondered why I demanded that every contact turn be an energy management turn. Yes that included turns in the pattern. Are they not maneuvering flight?

Re: Power lines

Is this how you make a 180 out of a 182

Re: Power lines

Dave Wiley (some of you in the PNW may remember Dave) during float plane training taught me to approach unknown canyons, river crossings etc. "up sun" for inspection, in other words with the sun behind you, which makes wires more visible.

Now all I have to do is to remember to always put that into practice.

Re: Power lines

I had a somewhat close encounter with some lines today, running my 30 ton crane. The guy I was working with is an old construction hand, like me, and a friend, and when I first pulled up to the job site we first discussed the nearby lines. 20 minutes later, as I'm, rotating around with the load (a big solar array) I caught myself boomed down more then I needed to be and IF I had continued to rotate, and IF the array had swung on it's axis, I MAY have come within 2 or 3 ' of the 440 V lines. Not to make it more exciting then it was, (I never got closer then about 15') I re-remembered the lines (hard to see, duhhh) in plenty of time, and was not too close, and my buddy was paying attention, in fact when I brought it up later ("almost forgot about those lines) he said. "yeah, me too, then I remembered and was about to say something right when you stopped." So....not a huge deal, but the frigging irony of a crane being operated by a often low flying pilot who was setting solar panels getting tangled up was a bit much. Once the array was set on the pipe, and rotated into a true south position, it was noted that the power line clearance was about 6'. I had nothing to do with the locating of these poles, kind of a screw up on his part, it will be interesting to see if the utility squawks.
