2023-08-23Flying electric aircraft; what’s the difference?
New Vision Aviation President Joseph Oldham presents an overview of flying electric aircraft, drawing on operational experience accumulated since receiving their aircraft in March 2018, including over 220 flight hours and 3,000 nautical miles traveled without incident. The organization has conducted evaluations with FAA test pilots and engineers from multiple aviation companies developing advanced electric aircraft. A notable 2021 cross-country flight demonstrated solar-only charging capabilities, covering 227.9 nautical miles at an average fuel economy of 3.43 nm/kWh. -

An Archer Aviation Midnight electric vertical takeoff and landing (eVTOL) aircraft bearing FAA registration N302AX sits on a tarmac, with a person in a flight suit walking nearby. The Midnight is a multi-rotor eVTOL designed for urban air mobility operations. -
2023-05-02Unleaded aviation gasoline
Swift Fuels, a West Lafayette, Indiana-based company, presented on unleaded aviation gasoline at the Aviation Noise & Emissions Symposium 2023 at UC Davis. The company markets two premium unleaded avgas products: UL94, sold since 2015 with FAA STC approval and ASTM D7547 certification, and a forthcoming high-octane 100R formula. These fuels are designed as lead-free alternatives to conventional aviation gasoline, with approvals from both engine and airframe original equipment manufacturers. -
Alaska Airlines Biofuel-Powered Aircraft Refueling
A ground crew member wearing a high-visibility vest refuels an Alaska Airlines aircraft labeled 'Biofuel powered.' at what appears to be a tarmac fueling operation. The image is credited to Alaska Air Group, indicating this is an official promotional or documentary photo related to Alaska Airlines' sustainable aviation fuel initiatives. -
2023-03-01Aircraft Size Comparison – A320, A321, and Transcontinental/Transatlantic H2 Aircraft
The image compares four narrow-body aircraft configurations: the conventional Airbus A320 and A321, alongside two hydrogen-powered concept variants labeled 'Transcontinental H2' and 'Transatlantic H2.' The H2 variants show large cylindrical hydrogen fuel tanks visible in the aft fuselage section, illustrating how liquid hydrogen storage would be integrated into the A320/A321 airframe for medium- and long-range zero-emission flight. -
2023-01-23House Bill 1505 – Alternative Jet Fuel Industry in Washington
Washington House Bill 1505 (2023) aims to promote the production and use of sustainable aviation fuels (SAF) by establishing tax incentives, clean fuel credits, and research initiatives to grow the alternative jet fuel industry in the state. The bill defines 'alternative jet fuel' as lower-carbon fuels that can be blended with conventional jet fuel without modifying aircraft engines or existing infrastructure. Beyond reducing greenhouse gas emissions, the legislation highlights improved air quality benefits for airport workers and communities surrounding airports like Sea-Tac. -
2022-11-29Power of hydrogen – aircraft maintenance demonstration
Rolls-Royce technicians in high-visibility safety gear work on a jet engine mounted on a test stand bearing the Rolls-Royce logo and text referencing 'power of hydrogen' and 'decarbonise aviation.' This appears to be related to Rolls-Royce's hydrogen combustion engine testing program. -
Rolls-Royce tests a jet engine running on hydrogen
By Theo Leggett Business correspondent, BBC News In a windswept corner of a military site on Salisbury Plain a small aircraft jet engine is undergoing tests that could one day lead to huge changes within the aviation industry. The engine itself is almost completely conventional. It is a Rolls-Royce AE-2100A gas turbine, a design used -
SAMP-2015-0519-BP12-PortofSeattle Page 03
A presentation slide from Seattle-Tacoma International Airport's Sustainable Airport Master Plan outlines Air Emission and Energy Reduction Programs, covering airline partner infrastructure, fleet vehicles (renewable natural gas buses, alternative fuel taxis), and facility upgrades (LED lighting, EV charging stations). The slide notes Sea-Tac was the first airport in North America to receive the Airports Council International Carbon Accreditation Certification, and lists two additional awards including the 2014 Best Workplace Recycling Award from King County Solid Waste Division.
