Good evening everyone,
We are having an issue with our L2 capturing powerlines when the lines travel up a fairly steep hill. Originally we thought it was due to the size of the conductor, but the conductor stays the same size. The L2 has no problem capturing the conductor on the level ground. We have examples of 4-5 flights that have this issue.
Has anyone else run in to this?
I am assuming (sorry for the crude drawing) that the reflectivity of the conductor is causing the returns to bounce behind the aircraft. The ground is captured fine because there is enough random angle surfaces to vary the returns.
Because of this, I think if we flew downhill the returns would bouce ahead of the aircraft.
Does my theory seem reasonable?  
Any thoughts on how to overcome this?
Thanks!

You could try with a custom angle of the L2 ( instead of NADIR / 90° down )

I had thought of that.. but we are flying 1/2 mile+ segments of line. I may end up having to break out the sections of line with aggressive terrain changes.
I was hoping someone would chime in about my theory of the cause. Has anyone flown powerlines, ski lifts etc that have a steep climb..
