Yep. I use it all the time to avoid airspace. (And mountains.) However, I've noticed that the vertical course line is very "noisy" in that it wanders up and down quite a bit in flight, even with WAAS. And even in straight and level flight. (Can post a video of it in S&L if anyone would like.)
It's more like having an Instantaneous VSI than a conventional (slow) one. I would like a (user selectable?) way to damp out the VP response to more like a 5 second sample time.
And you all say ... ?
