I feel that all ATPs should spend at least one week a year flying ultralights, other than sailplanes and powered hang gliders, you don't get simpler. They're a challenge and a delight to fly, real seat-of-the-pants stuff.
Now that's what I call a narrow margin for error. Its like with some sports motorbikes, easy to throw around and deceptively forgiving on corners until you hit a patch of oil, then you're on your ass. I personally prefer to have a few thousand feet between me and the ground before messing around.
We have a similar arrangement at our airfield, although the road has a row of tall trees on the rwy side, so that gives us a minimum approach height. The only downside it that it's a short field so you have to be pretty snappy once you're past the tree line.
The whole green tax thing is a ton of bullplop. I bet if they disbanded the whole EU central administration, the number of rainforests needed to be chopped down to fuel that insatiable red tape machine would be vastly reduced. Not to mention the reduction in hot air emissions from all that double talk.
