On the Boeing 737 MAX, MCAS was designed to mimic the pitching behavior of the aircraft in the previous generation of the series, the Boeing 737 NG. In April 2019, Boeing acknowledged that MCAS played a role in both accidents and stated that MCAS was not a stall prevention system. However, the recovery procedure specified by Boeing and the FAA failed to prevent the crash of Ethiopian Airlines Flight 302, resulting in a global grounding of all 737 MAX aircraft pending investigation and software patches. On November 10, 2018, twelve days after the crash of Lion Air Flight 610, Boeing publicly disclosed MCAS in discussions with airline operators and other aviation representatives. ![]() The first 737 MAX was delivered to the customer in May 2017.ĭuring aircraft certification, Boeing removed the MCAS description from the MAX flight manuals, leaving pilots unaware of the system when the aircraft entered service. ![]() The glider has also undergone some changes. The main change was the use of more powerful and larger CFM International LEAP-1B engines.

Technical Advisory Group (TAG) administrator to this TC and SC is the American Society for Quality (ASQ). These standards were developed by the International Organization for Standardization (ISO) Technical Committee (TC) 207, Environmental management, Subcommittee 7, Greenhouse gas and climate change management and related activities. ISO 14064, Greenhouse Gases, is a group of standards that provides guidance at the organization and project level for quantifying, monitoring, and reporting of greenhouse gas emission reductions or removal enhancements. It was developed by the American Institute of Aeronautics and Astronautics (AIAA).īeyond the aviation industry, guidelines for greenhouse gas emissions and other vital sustainability metrics are found in many national and international standards. AIAA R-154, Recommended Practice: When Flight Modeling is Used to Reduce Flight Testing Supporting Aircraft Certification, is a standard that outlines a set of recommended practices for an applicant to accomplish when flight modelling is being developed, proposed, and used to reduce flight testing relative to established aircraft certification practices. X-planes-a designation conferred by the Air Force for development programs that seek to create revolutionary experimental aircraft configurations-are not the only use of flight modeling. SAE AIR 6183, Procedures for the Calculation of Airplane Fuel Consumption, developed by SAE International for use by model developers.ASTM D7826, Standard Guide for Evaluation of New Aviation Gasolines and New Aviation Gasoline Additives, developed by ASTM International.The standards community has produced numerous documents that guide aviation fuels-both in their composition, and in the measurement of their use. The X-plane’s unique wing configuration, combined with modifications to propulsion systems, materials, and systems architecture, may result in up to 30% less fuel consumption than currently operating aircraft. One potential improvement that the X-66A seeks to offer is reduced fuel consumption. ![]() “With this experimental aircraft, we’re aiming high to demonstrate the kinds of energy-saving, emissions-reducing technologies the aviation industry needs.” ![]() “To reach our goal of net zero aviation emissions by 2050, we need transformative aircraft concepts like the ones we’re flying on the X-66A,” said Bob Pearce, associate administrator for NASA’s Aeronautics Research Mission Directorate. As such, more sustainable version of this aircraft could have a significant impact on emissions. The MD-90-and thus, the X-66A-is a single-aisle aircraft, which accounts for nearly half of worldwide aviation emissions. Aviation Climate Action Plan-specifically, net-zero aviation greenhouse gas emissions. The X-66A, which will modify an MD-90 aircraft with a shortened fuselage and extra-long, thin wings, is specifically focused on supporting the U.S. NASA and Boeing have announced that an experimental aircraft designated as the X-66A is the newest X-plane-a virtual plane produced through NASA’s Sustainable Flight Demonstrator project that will model changes to existing aircraft to reduce aviation emissions.Įxperimental aircraft have been used by NASA since the 1940s to support research into new technologies or concepts, unmanned test missiles, and prototypes. Standards guide reduced emissions and flight modeling for the aviation industry
