Aside from his royal duties, Prince William just started his new job as an air ambulance pilot on Monday. After completing his 1,500 hours of flight experience and passing a series of trainings and exams, the Duke of Cambridge is ready to rescue emergency medical patients within 90 seconds.

BBC reports the father of almost two-year-old, Prince George and 2-month-old Princess Charlotte will be fying a helicopter under the East Anglian Air Ambulance as a response to 999 emergency calls.

Part of his role as an air ambulance pilot is to check weather forecasts, aviation warnings, and the condition of the helicopter to ensure safety. Pilots should be "meticulous" in inspecting the engines, rotors, and the bodies, as well as making sure helipads at the hospitals are ready for landing.

"They will also do planning, so they will look at fuel levels and locations they can refuel at," said national director of the Association of Air Ambulances, Clive Dickin. "They do the pre-brief in the morning and they will go through the specifics with the crew. Then of course it goes on to flying missions."

Prince William, who had previous experiences as a RAF search and rescue pilot is tasked to fly the air ambulance to the patient's location within 90 seconds upon call alert. The helicopter can then land of fields, motor ways, and even at people's backyards.

"They will occasionally assist and help by carrying bags and equipment. They do form a valuable part of the team, but their primary role is making sure the aircraft is safe at all times," Dickins added, saying pilots really haven't undergone medical trainings.

With a salary about £40,000 a year, Prince William said he is going to donate his earnings to charity. The second in line to the throne will work for four days on and four days off, in one of the following scheduled shifts: 7:00 to 16:30 and 16:30 until midnight, whatever his royal duties permit.
