It should be obvious from this case that any type of aerial or public transport work carried out on either a UK or foreign registered aircraft without the required pilot qualifications and AOC documentation is illegal.
This includes private aircraft used for a business and persons flying on board such aircraft as part of their employment. I would suggest over the last two decades a lot of air to air photography seen in magazines is in breach of these rules.
Questions must also be raised over parachute aircraft operations in the UK.
Ibbotson was clearly getting material benefits from his parachute flying in acquiring flying hours.
I would suggest that most of the so called Wingly flights are also in breach of the regulations.
