Whilst you are absolutely correct, the confusion is not going to go away whilst the PFA on their website under "accepted aircraft" still catagorise under Microlight and Group A headings. Also, suppliers of kit aircraft in the UK still refer to either microlight or Group A versions (for example the adverts in this months "Flyer" magazine placed by Lewis Aviation for the Zenair Zodiac and 701 kits).
By the way, has anyone got an up to date list of accepted PFA permit aircraft, as the one on the PFA web site does not appear to have been updated for yonks (for example no mention of Vans RV7 8 or 9). I would ask the PFA myself but I understand they are a touch busy with relocation to the midlands and are therefore incomudicado.
