It might not seem like much but this really does add a lot of realism to flights. Mostly during take off and approach or very low flying. Since MSFS20 never had realistic power lines anywhere it was easy to just ignore the wireless poles. Now I must consider power lines near airports everywhere, just like in the real world and that changes things quite a bit.
I forgot I had the add on while approaching Auburn Muni near Seattle and I hit power lines on approach to 16. This add on wakes you up.
It’s also a great idea to get the chair lifts and gondolas as well to fully round out the incredible immersion both add.
