I personally take my power students to barren airfields for landing
practice, even though it costs $$$$s to get there. I know quite
a few other instructors (including helicopter) who do the same.
Good for them!

Great, but keep in mind helicopters need a hard surface for this training, the
surface can be a hard field at Falcon we training on the groomed grass. Most
helicopter pilots try to be good citizens. In fact may times I have been blown
by a single or twin that could have pushed to just a little different angle and
he would not have dusted me.

Helicopters avoid the flow of fixed wing traffic in the pattern.
