He’s never been an RAF Pilot so is incorrectly dressed - if he was then his name would be in the London Gazette. It isn’t apart from his honorary appointment. Unless the Defence Council have granted him permission to wear them (which would have attracted media attention at the time) then it looks like it is pure bloating and Waltery.
You can find his Gazette entry here for his honorary appointment:

His renewal is here:

I can’t see a further renewal from September 2023 and so I suspect he is no longer dressing up in one of His Majesty’s finest uniforms.
