Karkel:
I look forward to the flight tests! It sounds like you have the better part
of a year to wait,
though. Whatever, this is progress - a design coming with PFA approval is a
very good thing.
I have to say that one of the things that attracted me to the Europa in the
first place
was the rather rigorous approval process required in the UK by the PFA to
get a
homebuilt design flying. As opposed to the rather "buyer-beware,
laissiez-faire" attitude
in the states, it's my impression that a PFA-approved design will at least
have been
conservatively designed and reviewed by several pairs of knowledgeable eyes.
I still haven't seen an American kitplane vendor ( outside of Van's ) that
openly displays
recovery from a 12-turn fully developed spin on their promotional videos.
Maybe that
was just Ivan's design directive, but I like to think the PFA has something
to do with it...
