There’s no age limit to start flying with an instructor. The counter of flying hours can only be set when he’s fourteen.
IIRC William never did log enough hours to be a solo pilot (he was a co pilot) so maybe getting George started young is his way of ensuring George exceeds him?
William is a fully qualified helicopter pilot. I don’t lnow how many ratings he has, but he’s keeping his licence current.
He’s a fully qualified co pilot.
As I didn’t find a definitive answer on the big old internet about William’s qualifications, I went to study the pictures found for him in the helicopter.
Now, firstly, most photos show him in the seat on the right side.
Secondly, there’s no fixed position for the pilot and co pilot in a helicopter, it depends on the model, but the majority of helicopters place the co pilot on the right.
Here’s an article that explains a little about the seating:
