2023-05-01Fello’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. -
2023-04-06Delta Air Lines Airbus A330 Taxiing at Sea-Tac Airport International Terminal
A Delta Air Lines Airbus A330 (registration N623NW) taxis on the apron at Seattle-Tacoma International Airport, with gates S7–S10 visible in the background. Aircraft from JAL (Japan Airlines), Lufthansa, British Airways, and Qatar Airways are parked at the international terminal gates. -
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. -
2022-11-28Aircraft 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. -
2020-04-14Airbus 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. -
1995-06-28Aircraft Emissions Rates for Landing/Takeoff Cycles – A300, 757, and 737 Aircraft
Technical report showing aircraft engine emissions data for different aircraft types (A300, 757, 737) across various operational modes including takeoff, taxi, climb, and approach phases. Contains detailed emissions measurements for CO, HC, NOx, SOx, and particulates in kg/hr/engine units.
