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.
