time. At all bases at least one of the helicopters is on stand-by at any time. The Florø base is operated by the civilian contractor CHC Helikopter Service until the new SAR Queen helicopters are ready. The helicopters are manned by two pilots, a systems operator, a navigator, a technician/lift operator, a rescue swimmer and an anaesthesiologist. Five of these are military personnel, while the anaesthesiologists work for the local health trust and are funded through them. The Sea Kings fly a combined 4,500 hours per year. Half of these are used for missions, the remainder for training. Because the unit operates under military rules, it has a stricter training regime than civilian operators. It can also operate under more severe weather conditions. The bases have on-call rooms and a crew on duty at all times. The squadron aims as an average scrambling time of 15 minutes; this varies between 10 and 25 minutes depending on the time of day, the layout of the base and preparations. The 330 Squadron is part of the National Air Ambulance Service. It carries out about 800 missions per year, or about ten percent of the total helicopter ambulance missions in Norway. The unit's helicopters are used when the ordinary helicopter ambulances (Eurocopter EC135, EC145 and AgustaWestland AW139) are unable to operate due to weather; missions in which a large cabin is needed such as due to the number of patients or an incubator; and in areas where the Sea Kings are closer and areas where there is no ordinary air ambulance service. Ambulance use must be permitted by the JRCCs. When not used for SAR missions, the Sea Kings may be used for auxiliary and transport missions within the armed forces, assisting the Norwegian Police Service, aerial firefighting and anti-pollution. Bases The following is a list of bases used by the 330 Sqn. It denotes the period they were in use, the medical provider, the number of missions and flight-hours in 2013. Iceland The Royal Norwegian Navy Air Service ordered twelve Northrop N-3PB Nomads on 12 March 1940. This was the first-ever order for Northrop Corporation. By the time the first aircraft was finished in December 1940, Germany had invaded Norway. The aircraft were therefore transferred to Little Norway in Toronto, Ontario, Canada. During late fall the Norwegian Nygaardsvold's Cabinet agreed with the Royal Air Force that the exiled Norwegian forces could use
