The prince, 32, is considering taking a job as an air ambulance pilot close to the country home he and wife Kate have been renovating in Norfolk.
Flying helicopters for the East Anglian Air Ambulance service would enable William to return to his love of flying while making a contribution to public life – using the skills he learned in the Royal Air Force.
"The Duke of Cambridge is currently considering his options and an announcement will be made in due course," a spokesman for William says.
The prince clearly misses being in the air. During the recent tour of New Zealand, William was wistful when he visited the local air force museum in Christchurch.
"He told me that being in a hall full of aircraft made him long to be flying again," Peter Townsend, chief executive of the Chamber of Commerce, said. "He's got his private license and he is hoping for his commercial one."
Last year, William decided to leave the RAF in North Wales after flying rescue helicopters over the sea and rugged mountainous terrain for more than three years.
At the very least, William will be riding in a helicopter. The Queen has leased a $13 million Agusta A190S for use by the working members of her family, including William and Kate, though they're not expected to use it more often than other members of the extended Windsor clan.
