x effects of transatlantic flights in winter shows westbound flights climate forcing can be lowered by up to 60% and ~25% for jet stream-following eastbound flights, costing 10–15% more due to longer distances and lower altitudes consuming more fuel, but 0.5% costs increase can reduce climate forcing by up to 25%.

Noise-generating aircraft propeller. Aircraft noise is noise pollution produced by an aircraft or its components, whether on the ground while parked such as auxiliary power units, while taxiing, on run-up from propeller and jet exhaust, during takeoff, underneath and lateral to departure and arrival paths, over-flying while en route, or during landing.
By increasing efficiency, a lower cruise-speed augments the range and reduces the environmental impact of aviation.According to a research project completed in 2024 and focusing on short to medium range passenger aircraft, design for subsonic instead of transonic speed (about 15% less speed) with turboprop instead of turbofan propulsion would save 21% of fuel compared to an aircraft of ...
A relativistic jet emitted from galaxy M87, as seen by the Hubble Space Telescope. A jet is a stream of fluid that is projected into a surrounding medium, usually from some kind of a nozzle, aperture or orifice. [1] Jets can travel long distances [quantify] without dissipating. Jet fluid has higher speed compared to the surrounding fluid medium.
Volcanic ash deposits on a parked McDonnell-Douglas DC-10-30 during the 1991 eruption of Mount Pinatubo, causing the aircraft to rest on its tail.While falling ash behaves in a similar manner to snow, the sheer weight of deposits can cause serious damage to buildings and vehicles, as seen here, where the deposits were able to cause the 120 ton airliner's centre of gravity to shift.
An aviation biofuel (also known as bio-jet fuel, [1] sustainable aviation fuel (SAF) or bio-aviation fuel (BAF) [2]) is a biofuel used to power aircraft. The International Air Transport Association (IATA) considers it a key element in reducing the environmental impact of aviation . [ 3 ]
On February 4, Jet Rescue Air Ambulance released the names of the crew and passengers aboard the flight: captain Alan Alejandro Montoya Perales, co-pilot Josué de Jesús Juárez Juárez, Dr. Raúl Meza Arredondo, paramedic Rodrigo López Padilla, pediatric patient Valentina Guzmán Murillo and her mother Lizeth Murillo Ozuna.
Non-UK jet engines built in the 1930s and 1940s had to be overhauled every 10 or 20 hours due to creep failure and other types of damage to blades. British engines, however, utilised Nimonic alloys which allowed extended use without overhaul, engines such as the Rolls-Royce Welland and Rolls-Royce Derwent , [ 18 ] and by 1949 the de Havilland ...
