Bell 505 Becomes World’s First Single Engine Helicopter to Fly Using 100% SAF

Bell Textron announced the Bell 505 completed its first flight fueled solely by 100% Sustainable Aviation Fuel (SAF), marking the first-ever single-engine helicopter to fly with 100% SAF. Bell collaborated with Safran Helicopter Engines, Neste, GKN Aerospace and Virent Inc. to make this Bell 505 flight possible.

To achieve this flight, Bell collaborated with Safran Helicopter Engines, manufacturer of the Arrius 2R engine on the Bell 505; GKN Aerospace, the fuel system component supplier; Neste, the SAF supplier; and Virent, Inc., a Marathon Petroleum Corp. subsidiary that manufactures renewable fuels and chemicals. Safran Helicopter Engines and GKN Aerospace conducted thorough testing on the engine and fuel system components.

Neste and Virent collaborated to blend, test, and deliver the SAF for this project as a 100% drop-in fuel. SAF, made from used cooking oil or other bio-based feedstocks, typically must be blended with petroleum products because it doesn’t include a component called “aromatics,” which is required to meet today’s aviation fuel specifications. Virent manufactures an aromatics component made from renewable plant sugars, which was added to Neste’s neat SAF, eliminating the need to blend SAF with petroleum fuel. The SAF supplied for this test flight by Neste and Virent is therefore a “100% drop-in” replacement for petroleum-based aviation fuel, requiring no engine modifications.

Bell’s own training fleet and demonstration aircraft currently use SAF in their operations. The team continues to guide customer conversations around its implementation and monitors SAF testing in a dedicated Bell 505 with Safran Helicopter Engines. This flight supports Textron’s Achieve 2025 Sustainable Footprint goal for 20% reduction in greenhouse gas emissions across the enterprise, among other sustainability initiatives.

The Bell 505 is a five-seat aircraft designed for safety and efficiency while using the most advanced technology to date. The platform uses a fully integrated Garmin G1000H NXi avionics suite and Safran Arrius 2R engine with a dual-channel FADEC.

When Ratan Tata was denied entry to the airfield at the Aero India show, he waited

During our visit to Aero India 2019, we had the unexpected opportunity to see Ratan Tata at the event, which was a thrilling moment for us. However, there was a surprising hiccup when the security staff didn’t allow him to enter due to a lack of a security pass.

Despite this, he remained calm and patiently waited for about 20 minutes until a member of the Tata team brought him the required pass, after which he calmly proceeded inside. It was a humbling sight, showcasing his composed demeanor even in such situations.

Ratan Tata ji is not only a renowned industrialist but also a trained pilot, holding a pilot’s license. In 2007, he became the first Indian civilian to fly the F-16 Falcon during the Aero India show in Bangalore—a proud moment for the nation.

His passion for aviation extended beyond flying, as he played a key role in shaping India’s aerospace industry. Under his leadership, Tata ventured into manufacturing and maintaining aerospace components while upholding its legacy of quality. Notably, Tata’s collaboration with Airbus to develop and manufacture the C295 aircraft is a testament to its growing influence in the sector.
