Prince William is due to receive his wings after completing an advance helicopter training course, taking him a step closer to becoming an RAF search and rescue pilot.
The second in line to the throne will graduate alongside fellow students at RAF Shawbury and will be presented with a flying badge by his father.
The Prince of Wales, accompanied by the Duchess of Cornwall, will present long-service and operational medals to RAF personnel from the Shropshire base, before attending the graduation ceremony of the No 115 Multi-Engine Advanced Rotary Wing Course.
Prince William, known as Flight Lieutenant Wales, spent 12 months training at RAF Shawbury. Later in the month he will move to RAF Valley on Anglesey, where he will be taught to use his new skills to fly Sea King helicopters.
The 27-year-old will learn to manoeuvre the aircraft with pinpoint accuracy, enabling him to rescue stricken mountaineers or exhausted swimmers in treacherous conditions.
William is following in the footsteps of his father, Charles, who served as a Royal Navy helicopter pilot, as did his uncle, the Duke of York, a Sea King helicopter pilot during the 1982 Falklands War.
