Prince William has no solo flying privileges he hasn't earned, and any
flying he might do now or in the future I'm quite certain will be
conducted totally within the confines of his level of demonstrated
competence.

Which privileges did he miss out on by skipping 195 of the 208 weeks that a
normal RAF pilot spends in training?

Prince William's "character" as you put it, although at a very high
level, will in no way open doors for him to fly anything, or in fact do
anything, in an aircraft he hasn't been authorized by competent RAF
authority to fly.

Uh-huh.
