“Whilst there may be microlights in Laa-laa land, their regulation is surely a BMAA / CAA issue?”
No, the LAA aircraft are regulated by the LAA with CAA oversight, in the same way that BMAA aircraft are regulated by the BMAA with CAA oversight. The BMAA have no technical info on the LAA fleet, as the two organizations compete. Interestingly, as far as a home built aircraft on the LAA system is concerned, there is no difference in the weight of regulation between an aerobatic RV with 200hp, my VLA and a Micro. The only “step up” is for 4 seat aircraft.
