My view on this, having sat both sides of the table for a few job interviews is only put things on your CV you're prepared to talk about.
I know you're a keep aviatrix, so yes - list it. I did have a chap I interviewed for a job listed an aeronautical related hobby on his CV, so to settle him down, I started by asking some fairly basic questions about it. He demonstrated quite clearly no understanding of what he'd put on his CV, and it went rather downhill subsequently!
