  • The new engine design touted to power the successor to Boeing’s 737 MAX

    By Dominic Gates Seattle Times aerospace reporter PARIS — Airbus and Boeing are each helping with tests of a radical new engine design with an open fan being developed by CFM International, making it a prime candidate to power the next generation of all new airplanes in the mid-to-late 2030s. The new engine with a

    Fello’fly: Wake Energy Retrieval – Formation Flying

    Airbus's 'fello'fly' program explores formation flying as a fuel-saving technique, where a follower aircraft positions itself in the smooth updraft of a leading aircraft's wake to recover otherwise wasted kinetic energy. This approach can reduce trip fuel consumption and emissions by around 5% for the follower aircraft, making it most beneficial on long-haul routes exceeding 2,000 nautical miles. Key factors affecting savings include aircraft pairing, the follower's position on the vortex, time spent in formation, and fuel used to enter the formation.

    Aircraft 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.

    Aircraft Approaching Airport Landing System

    A large four-engine widebody aircraft, consistent with an Airbus A380 configuration, is photographed head-on during final approach, framed by a red-and-white approach lighting system (ALS) gantry with yellow omnidirectional lights. Landing gear is fully extended, indicating imminent touchdown. No visible airline livery, watermarks, or location-specific markings are clearly discernible.

    Airbus A320 “Whistle”: ONCC Technical Committee Meeting, April 14, 2020

    Airbus A320 family aircraft (A318, A319, A320, A321) manufactured before 2014 produce a distinctive high-pitched whistling noise during descent, caused by airflow passing through Fuel Over Pressure Protector (FOPP) cavities located on each wing. The noise fades once the landing gear is deployed. A small device called a vortex generator, installed just in front of each vent opening, has been identified as an effective fix, reducing noise levels by up to 4 decibels during the approach phase.

Issues

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
