There’s a US website called Helicopter Online Groundschool, aka HOGS. Apparently, there are a number of Aussie pilots/students that are subscribers. Anyone using this site to study for Aussie PPL/CPL exams? Their jurisdiction is obviously the FAA, and Oz is ruled by CASA. So I’m wondering about the suitability of their online content for Aussie pilots/students. I guess if they’re teaching principles of flight / aeronautics, their content might be universal enough to be relevant, I just don’t know whether it’s worth a monthly subscription.
