There's a photo in the RAF club of three kings wearing RAF uniform with pilots' wings. As far as I know both Edward VIII and George VI were qualified pilots but I have never heard that George V learned to fly, so in his case I think the wings really were honorary. One day of course we'll have a "proper" RAF pilot on the throne.
Although George V wore the pilots brevet on his uniform he was never trained to fly. The Duke of York (later George VI) served in the RAF 1918-1919, gaining his wings in 1919. He was followed by his brothers Edward Prince of Wales (King Edward VIII, later Duke of Windsor) in 1929 and Prince George (later Duke of Kent) in 1930.
Here's a picture of three kings with wings.
