Stockholm Sector N is an all level sector covering the middle part of Sweden FIR from about 61°N to about 64°N. It operates on 132.150 MHz.

The main tasks of sector N are:

• En-route traffic in the middle part of Sweden FIR
• Top-down coverage for a number of regional aerodromes located within the sector, when no local ATC is operating

Although Sector N has many routes going both east-west and south-north (and vice versa), the main traffic flow tends to be from the south toward the north-east and vice versa. During the winter season, a considerable amount of traffic in the sector will be made up of flight to and from Northern Finland.

Sector N will usually be combined with sector K, but can also be extended to the south by being combined with Sector 3 and the Stockholm lower sectors.
