 During winter the helicopters must often follow a coastal flight route of Porsangerfjorden before heading east to Kirkenes or west to Tromsø, to avoid icing. The Sea Kings have an operational radius of 740 kilometers (460 mi); in combination with refueling possibilities at Bjørnøya and Hopen, this allows all parts of the Norwegian exclusive economic zone to be covered. Because of issues with icing, the helicopters cannot fly higher than 200 meters (660 ft) altitude.
