The Duchess of Cambridge showed off her aerial skills in a flight simulator as her husband was left holding her handbag.
William, who learnt to fly with the RAF and piloted the service's search and rescue helicopters, watched as Kate took the controls of the light aircraft simulator during the visit.
Group Captain Al Lewis said of the visit: "It was a really unique experience and the cadets only found out an hour before they arrived.
"Given that we haven't had much activity over the last years it was a real morale boost.
"It was wonderful for them, too, to see the real legacy that the Duke of Edinburgh left.
"I spoke to the Duke [of Cambridge] about whether he was still flying and he said he was very keen to try to keep his flying hours up. He clearly misses flying professionally.
"It was interesting to see the Duchess get in the simulator instead of him. She did very well. He was goading her to say, 'well it's not as easy as it seems'."
