Gliders are not required to stay VFR in the UK in class G airspace. They are "somehow exempt".
I am puzzled by a lot of the statements in this thread. Maybe someone could explain exactly just what gilders are permitted to do (in UK airspace) that powered aircraft are not. It would be nice to see the bit of the ANO or Rules of the Air that permits it too.
Regards,
Puzzled of the UK
