And you have forgotten the UK CAA-only induced madness of the NPPL minimas:
For a NPPL microlighter flying a Eurostar below 3,000ft: 3km in flight vis outside controlled airspace
For a NPPL SSEA pilot flying a light aircraft Eurostar below 3,000ft: 5km vis outside controlled airspace.
Uh?
Especially as one of our chaps has just bought a light aircraft Eurostar and reregistered it as a micro one!
