Thanks for that 212man.
I think 113 (1) might be passable if you accept the assumption that I would be getting paid for flying the helicopter, not "providing carriage"
Not too sure about 115(1) though - if it isn't PT - but I'm getting paid - does that make it de facto Aerial Work, and as such requiring a permission from Sec of State?
Anybody else out there actually tried applying for such a permission under similar circs to this?
