Boeing Commits to Deliver Commercial Airplanes Ready to Fly on 100% Sustainable Fuels
SEATTLE, Jan. 22, 2021 /PRNewswire/ -- Boeing (NYSE: BA) is setting an ambitious target to advance the long-term sustainability of commercial aviation, committing that its commercial airplanes are capable and certified to fly on 100% sustainable aviation fuels by 2030. Boeing has previously conducted successful test flights replacing petroleum jet fuel with 100% sustainable fuels to address the urgent challenge of climate change.
According to the Air Transport Action Group, U.S. Department of Energy and several other scientific studies, sustainable aviation fuels reduce CO2 emissions by up to 80% over the fuel's life cycle with the potential to reach 100% in the future. Today, sustainable aviation fuels are mixed directly with conventional jet fuel up to a 50/50 blend — the maximum allowed under current fuel specifications. In order to meet aviation's commitment for reducing carbon emissions by 50% from 2005 levels by 2050, airplanes need the capability to fly on 100% sustainable aviation fuels well before 2050.
"Our industry and customers are committed to addressing climate change, and sustainable aviation fuels are the safest and most measurable solution to reduce aviation carbon emissions in the coming decades," said Boeing Commercial Airplanes President and CEO Stan Deal. "We're committed to working with regulators, engine companies and other key stakeholders to ensure our airplanes and eventually our industry can fly entirely on sustainable jet fuels."
Boeing's commitment is to determine what changes are required for its current and future commercial airplanes to fly on 100% sustainable fuels, and to work with regulatory authorities and across the industry to raise the blending limit for expanded use.
"With a long history of innovation in sustainable aviation fuels, certifying our family of airplanes to fly on 100% sustainable fuels significantly advances Boeing's deep commitment to innovate and operate to make the world better," Chief Sustainability Officer Chris Raymond said. "Sustainable aviation fuels are proven, used every day, and have the most immediate and greatest potential to reduce carbon emissions in the near and long term when we work together as an industry."
Boeing has been a pioneer in making sustainable aviation fuels a reality, partnering globally with airlines, industry, governments and research institutions to expand limited supplies and reduce the fuels' cost. Boeing worked with airlines, engine manufacturers and others to conduct biofuel test flights starting in 2008 and gain approval for sustainable fuels in 2011. In 2018, the Boeing ecoDemonstrator flight-test program made the world's first commercial airplane flight using 100% sustainable fuels with a 777 Freighter, in collaboration with FedEx Express.
Sustainable aviation fuels can be made from a wide variety of feedstocks, including non-edible plants, agricultural and forestry waste, non-recyclable household waste, industrial plant off-gassing and other sources. Sustainability of the fuels is assured through strong, credible sustainability certifications through third-party organizations such as the Roundtable on Sustainable Biomaterials.

Airbus unveils its helicopter Flightlab to test tomorrow’s technologies - Helicopters - Airbus
Marignane, 22 January 2021 – Airbus Helicopters has started in-flight tests on board its Flightlab, a platform-agnostic flying laboratory exclusively dedicated to maturing new technologies. Airbus Helicopters' Flightlab provides an agile and efficient test bed to quickly test technologies that could later equip Airbus' current helicopter range, and even more disruptive ones for future fixed-wing aircraft or (e)VTOL platforms.
Airbus Helicopters intends to pursue the testing of hybrid and electric propulsion technologies with its Flightlab demonstrator, as well as exploring autonomy, and other technologies aimed at reducing helicopter sound levels or improving maintenance and flight safety.
"Investing in the future remains essential, even in times of crisis, especially when those innovations bring added value to our customers by targeting increased safety, reduced pilot workload, and reduced sound levels," said Bruno Even, Airbus Helicopters CEO. "Having a dedicated platform to test these new technologies brings the future of flight a step closer and is a clear reflection of our priorities at Airbus Helicopters," he added.
Flight tests started last April when the demonstrator was used to measure helicopter sound levels in urban areas and to particularly study how buildings may affect people's perception. First results show that buildings play an important role in masking or amplifying sound levels and these studies will be instrumental when the time comes for sound modelling and regulation setting, especially for Urban Air Mobility (UAM) initiatives. Testing was pursued in December to evaluate the Rotor Strike Alerting System (RSAS) aimed at alerting crews about the imminent risk of collision with the main and tail rotors.
Tests this year will include an image-detection solution with cameras to enable low altitude navigation, the viability of a dedicated Health and Usage Monitoring System (HUMS) for light helicopters, and an Engine Back-up System, which will provide emergency electric power in the event of a turbine failure. Testing on the Flightlab will continue in 2022 in order to evaluate a new ergonomic design of intuitive pilot flight controls intended to further reduce pilot workload, which could be applicable to traditional helicopters as well as other VTOL formulas such as UAM.
The Flightlab is an Airbus-wide initiative, which reflects the company's approach to innovation focused on delivering value to customers. Airbus already has several well-known Flightlabs such as the A340 MSN1, used to assess the feasibility of introducing laminar flow wing technology on a large airliner, and the A350 Airspace Explorer used to evaluate connected cabin technologies inflight.
