Avinor to Explore the Potential for Dedicated Airspace Routes for Electric Aviation

Over a six‑month period, 126 flights were conducted. The tests demonstrate that electric aircraft can operate safely alongside conventional air traffic. Avinor will now assess how electric aircraft can be well integrated into Norwegian airspace.

“Avinor will be a driving force and enabler for fossil‑free aviation. Prioritising and placing new, zero‑emission aircraft in the airspace in a smart way can be one such measure – not unlike how electric cars were once given access to public transport lanes,” says Jan Gunnar Pedersen, Executive Vice President of Avinor Air Navigation Services.

Safe in Traffic – Now Scaling Is the Next Step

“The results open up new opportunities, such as more direct routings, greater flexibility in altitude changes and improved noise considerations,” Pedersen says.

Today’s airspace is largely designed for aircraft with high climb performance. For battery‑electric aircraft, long climb phases, fixed altitudes and circuitous routings can reduce range and operational flexibility.

“We have demonstrated that electric aircraft can operate side by side with other aviation without compromising safety. Now we must enable scaling,” says Pedersen.

The final report shows that electric aircraft can operate safely and efficiently in Norway. At the same time, the tests point to a need for adaptations to airspace design and regulations before the technology can be scaled for commercial operations.

The Need to Design Dedicated “E‑Routes”

Experience from the test programme indicates that electric aircraft perform best at lower altitudes and with more direct routings. This results in lower energy consumption, simpler flight planning and increased safety margins.

“If we are to introduce electric aircraft into commercial aviation, we must develop procedures and routes that are tailored to this type of aircraft – so‑called ‘e‑routes’,” Pedersen says.

“Our flights in the International Test Arena clearly demonstrated the capability of electric aircraft to deliver sustainable, economical and efficient air transport services, especially in areas where geographic challenges make access difficult. To truly unlock the full potential of these aircraft across the aviation eco‑system however, the collaborative development of routings that complement the unique characteristics of these aircraft is necessary and we look forward to working with Avinor to develop such routes,” says Simon Meakins, Director Advanced Air Mobility, Bristow Group.

Regulations and Reserves Must Also Be Assessed

Regulatory frameworks will also need to evolve to accommodate electric aircraft. The tests show that existing requirements for energy reserves and alternate airports may impose operational limitations on aircraft with shorter range.

“Electric aircraft have different characteristics from conventional aircraft. This means that regulations may need to evolve alongside new technology, provided safety is ensured through other, equally robust solutions. Our experience provides an important knowledge base for further regulatory work, both nationally and internationally.”

“The tests provide a solid foundation for future decisions concerning airports, airspace and regulation. If electric aviation is to succeed, authorities, operators, manufacturers and infrastructure providers must work closely together,” Pedersen concludes.

About the international test arena

Norway as an international test arena for zero‑ and low‑emission aviation is a government‑led initiative established by Avinor and the Civil Aviation Authority Norway, with financial support from the Norwegian Government. The test arena aims to enable a faster and more predictable introduction of new aviation technologies through practical testing and the development of regulatory frameworks.
