Swedavia and Luftfartsverket are the first in Europe to introduce a new air traffic approach concept. The new concept is commonly referred to as Established on RNP (EoR) and makes it possible for aircraft arriving at Stockholm Arlanda Airport to fly with curved approaches to a greater extent than before. The concept is an important step towards increasing the capacity, efficiency and sustainability of air traffic.

The new approach concept allows the airport to increase the landing rate per hour and reduces emissions, both for the aircraft flying the shorter, curved approach and for those flying the standard instrument landing approach. This is because fewer aircraft have to use the runway dedicated for arrivals, reducing the queue for that runway. To be able to fly curved approaches, airlines must have a special permit from their National Supervisory Authority.

The technique for curved approaches requires special equipment in the aircraft, specially trained pilots and special permission from their National Supervisory Authority. In addition to reducing the environmental impact, the introduction of the new approach concept also provides an incentive for airlines to invest in technique for curved approaches which, in the long run, makes it possible to avoid flying over noise-sensitive areas.
