Ada Elle,
Your leaps of logic from the discussion have me gasping for air.
First you want to keep all the existing weight limits and argue against any change, now you are going on about having 1500kg.
You have gone from one extreme to the other.
Also what the public or anyone in the media- who can't tell the difference between a Cessna and a Bi-plane thinks about what Ultralight means is not relevant. I don't care what Joe Blow thinks.
If you had not noticed we are not just rag and tube anymore, we have moved on and are actually called Recreational Aircraft.
Note: Recreational ie not for profit, Not for carrying commercial loads. For the fun and enjoyment of flying.
The whole idea is to have all the benefits of flying suitable aircraft that we can regulate and not have the costs and complexity of GA.
Even CASA seems to get it, why don't you?
