Kensington Palace announced the Duke of Cambridge's new employment this afternoon, saying he will be based at Cambridge and Norwich Airports and take on both day and night shifts from early 2015.
William, 32, will have to undergo at least five months of training in order to obtain his Air Transport Pilot's Licence (Helicopter). He'll begin as a co-pilot and then, after being trained, will be qualified as a helicopter commander.
It will require 14 exams and a flight test.
This will be the duke's primary job but the palace has said he'll continued to undertake royal roles including overseas trips. He'll also continue working with his patronages and charities.
The duke will be employed by Bond Air Services, making him the first royal in direct succession to the throne to sign an employment contract with a civil employer.
He will be paid but the salary will be donated to charity.
A spokesperson told BBC News: "The duke sees this as a true form of public service, helping people in their most difficult times. He regards his work with the RAF search and rescue force as having been an exceptional privilege and the duke wanted to make his own contribution to the outstanding work of the air ambulance service."
William was previously a search and rescue pilot for the RAF, based in Anglesey. During his time there, he took part in more than 150 search and rescue operations and clocked more than 1,300 flying hours.
