This is exactly right to my understanding and tagging. My
understanding and as I have mapped in the past a aeroway=helipad is
for a known built up permanent for the most part landing area. I
mapped a lot of these in Nepal.

This does sound like exactly the right tag for what we are planning on mapping.
