Arlanda Makes ATM History

Why It Matters

The EoR implementation boosts capacity without expanding infrastructure, delivering cost and environmental benefits that other congested hubs can replicate.

Key Takeaways

• First European airport using Established on RNP arrivals.
• Curved approaches reduce separation, boosting runway capacity.
• GPS‑based navigation cuts fuel burn and emissions.
• Swedavia and LFV partnership drives implementation.
• ICAO‑approved concept enhances safety while increasing throughput.

Pulse Analysis

Air traffic management in Europe faces mounting pressure as passenger numbers rebound and runway slots become scarce. Traditional straight‑in instrument approaches require generous separation buffers, limiting the number of landings an airport can handle per hour. Required Navigation Performance (RNP) standards, introduced by ICAO in 2018, allow aircraft to navigate precisely using satellite‑based positioning, opening the door to more flexible flight paths. By leveraging RNP, airports can redesign arrival routes to fit existing airspace more efficiently, a shift that underpins the latest innovation at Stockholm Arlanda.

The Established on RNP (EoR) concept transforms those flexible paths into curved approaches that align with Arlanda’s parallel runway configuration. Instead of a single straight trajectory, aircraft follow a series of GPS‑guided arcs, which reduces the lateral separation required between successive flights. Swedavia and the Swedish air navigation service provider LFV coordinated the procedural design, simulation testing, and regulatory approval, ensuring that safety margins meet ICAO standards. Early operational data indicate a 15‑percent increase in runway throughput and a measurable drop in fuel burn, directly supporting the airport’s sustainability targets.

EoR’s success at Arlanda signals a broader shift toward performance‑based navigation across congested hubs. By extracting additional capacity from existing runways, airlines can reduce delay‑related costs while passengers benefit from more reliable arrival times. The environmental upside—lower fuel consumption and reduced CO₂ emissions—aligns with Europe’s Green Deal objectives, making the model attractive to regulators and airport operators alike. As other European airports evaluate similar RNP‑based procedures, the Swedavia‑LFV collaboration may become a template for integrating advanced ATM concepts without costly infrastructure expansions.
