Guys,
The Glasair IIS RG is cleared for aerobatics (rolls (not snap rolls), loops and Cuban 8s) in the US, but it's not cleared to spin. In the UK it's not cleared for aerobatics at all (although I'm sure they've been rolled when no-one's looking).
So, why clear it for aerobatics if it's not cleared to spin? Surely running out of energy at the top of a loop can lead to a spin? So can a hammerhead, Immelmann, etc... I just don't get it this at all. Any ideas how this came to be? Or am I getting in a bit of a spin? Tying myself in loops?
Note: I'm thinking of building one of these masterpieces, so I'm not trying to call its capabilities into question! I think the PFA's attitude is intelligent - if one aspect of its aerobatic abilities is called into question, then it shouldn't be aerobatted - at least not by low-hour pilots like me.
