In a clip from a new BBC documentary Prince William talks about the worries and challenges he faces in his role as RAF search and rescue pilot.
"You have to analyse all the information you're given and make the best judgement," said William who is expecting his first child with wife Kate Middleton in July. "It is not easy. It makes you feel worried, concerned. You obviously want to make the right call.
"I have a duty of care for the crew, for the casualty in many cases as well, so you do have to think very carefully. Overall I've got three other guys I can rely on for my decision making."
The documentary, Helicopter Rescue, follows events at RMB Chivenor in Devon and RAF Valley in Anglesey, where the Duke of Cambridge is based.
This documentary won’t be the first time Prince William, who is known by his colleagues as Lieutenant Wales, has offered the public a glimpse of his RAF working life. In November 2012, behind-the-scenes pictures were released showing a typical 24-hour shift for the Prince in his official role as a Search and Rescue (SAR) pilot flying Royal Air Force Sea King helicopters. The photos show Kate Middleton's husband amongst his team members, on-call for emergencies and making tea during a break.
As William, 30, approaches the end of his current tour of duty, he faces a difficult decision over whether to continue his work in the services or follow in the footsteps of his parents Prince Charles and Princess Diana, by dedicating time to royal duties and charity work.
It won't be an easy decision for the Duke of Cambridge who explained during the BBC programme that there is "no greater feeling" than saving lives. William and his team rescued a Canadian tourist last year when she fell into a crevice while walking along the Anglesey coast and broke her leg. The RAF team saved the 58-year-old woman and took her to hospital in Bangor.
With William busy at work, Kate, who is almost six months pregnant, is "finally getting a chance to enjoy her pregnancy" according to an insider. The 31-year-old is reportedly spending time decorating the 21-room apartment in Kensington Palace, which she will move into with her husband and their new arrival, later this year.
Helicopter Rescue will air on BBC One on 8 April.
