The King officially handed over the role of Colonel-in-Chief of the Army Air Corps to the Prince of Wales during a visit to its Hampshire airfield.
Charles – who became the inaugural holder of the title 32 years ago – met with his eldest son in a rare joint official engagement at the Middle Wallop base on Monday afternoon to transfer the role.
The King’s decision to hand the role to William was seen as a blow to Harry when it was announced last year.
He said: “I do hope you’ll go from strength to strength in the future with the Prince of Wales as your new Colonel-in-Chief.
“The great thing is he’s a very good pilot indeed – so that’s encouraging.”
The aircraft was one of four involved in a rescue mission during the Battle of Jugroom Fort in 2007.
The King said: “Let me just say what a great joy it is to be with you even briefly on this occasion but also it is tinged with great sadness after 32 years of knowing you all, admiring your many activities and achievements through the time that I’ve been lucky enough to be Colonel-in-Chief of the Army Air Corps.”
General Nick Barton, who took part in the rescue operation, said it was a “unique honour” to meet the King who served as an important “figurehead” for the soldiers.
William embarked on his first engagement with the Army Air Corps after the King left, receiving a briefing on its work and inspecting training and operational aircraft as well as talking to soldiers.
He then left the base in an Apache as part of a capability flight.
Kensington Palace posted two images of the prince during his military service on X, showing a young William in 1998 and 2009 – standing next to a helicopter in one picture and smiling at the controls in another.
“Time flies!” the caption read.

Monday’s visit comes just days after Harry travelled to the UK to mark 10 years of the Invictus Games, without meeting up with his father and brother.
The King trained with the RAF while in his second year at the University of Cambridge and was given his wings in August 1971.
William served in the Army with the Blues and Royals and was an RAF search and rescue pilot for three years at RAF Valley in Anglesey, Wales.
