Air Nautique
The Super Air Nautique line-up of Nautique Boats is Correct Craft's crossover-wakeboarding focused model; the boat is outfitted for wakeboarding with a tower and ballast tanks from the factory. Furthermore, some Super Air Nautiques are in V-drive format, which creates a bigger wake for the rider. The first Air Nautique was built in 1997; it was built on the existing Sport Nautique Hull and had an automatic rear ballast system (Launch Control System or "LCS"). Other notable "landmarks" included Correct Craft's patented "Flight Control Tower", which was essentially a modified fishing tower. In 2019 Nautique released the Super Air Nautique G23 Paragon, this new release is the most expensive boat Nautique has created and is aimed at being the most luxurious experience on the water. In 2013 the Super Air Nautique has moved from being primarily for wakeboarding but now also wakesurfing. This has come with the addition of wake-plates located on the stern of the boat and ventilation systems that direct the exhaust into the propeller jet stream. The new features that Nautique has added is known as the Nautique Surf System (NSS).

Air Quality-Related Parameter Forecasting Using Soft Computing Techniques
Air is one of the main factors that maintain the balance of the earth’s environment. The World’s Air Pollution: Real-Time Air Quality Index clearly indicates the recent air pollution levels of the earth. Machine learning algorithms such as random forest (RF), linear regression (LR), and support vector regression (SVR) play an essential role as traditional algorithms for regression purposes.

Air Source Heat Pumps
An air source heat pump (ASHP) is a system that transfers heat from outside to inside a building, or vice versa. Under the principles of vapor compression refrigeration, an ASHP uses a refrigerant system involving a compressor and a condenser to absorb heat at one place and release it at another. They can be used as a space heater or cooler, and are sometimes called "reverse-cycle air conditioners". In domestic heating use, an ASHP absorbs heat from outside air and releases it inside the building, as hot air, hot water-filled radiators, underfloor heating and/or domestic hot water supply. The same system can often do the reverse in summer, cooling the inside of the house. When correctly specified, an ASHP can offer a full central heating solution and domestic hot water up to 80 °C.

Airborne Wind Energy
Airborne wind energy (AWE) is the direct use or generation of wind energy by the use of aerodynamic or aerostatic lift devices. AWE technology is able to harvest high altitude winds, in contrast to wind turbines, which use a rotor mounted on a tower. The term high-altitude wind power (HAWP) has been used to refer to AWE systems. However, semantically HAWP might also include wind energy conversion systems that are somehow positioned at a large height from the ground or sea surface. Various mechanisms are proposed for capturing the kinetic energy of winds such as kites, kytoons, aerostats, gliders, gliders with turbines for regenerative soaring, sailplanes with turbines, or other airfoils, including multiple-point building- or terrain-enabled holdings. Once the mechanical energy is derived from the wind's kinetic energy, then many options are available for using that mechanical energy: direct traction, conversion to electricity aloft or at ground station, conversion to laser or microwave for power beaming to other aircraft or ground receivers. Energy generated by a high-altitude system may be used aloft or sent to the ground surface by conducting cables, mechanical force through a tether, rotation of endless line loop, movement of changed chemicals, flow of high-pressure gases, flow of low-pressure gases, or laser or microwave power beams.

Airborne Wind Energy Systems
Because of the near-term risk of extreme weather events and other adverse consequences from climate change and, at least in the longer term, global fossil fuel depletion, there is worldwide interest in shifting to noncarbon energy sources, especially renewable energy (RE). Because of possible limitations on conventional renewable energy sources, researchers have looked for ways of overcoming these shortcomings by introducing radically new energy technologies. For wind energy, a possible alternative is airborne wind turbines.

Airbus Beluga XL
The Airbus BelugaXL (A330-743L) is a large transport aircraft based on the Airbus A330-200F built by Airbus to replace the original Airbus Beluga in the movement of oversized aircraft components like wings. The aircraft made its first flight on 19 July 2018, and received its type certification on 13 November 2019. The BelugaXL entered service with Airbus Transport on 9 January 2020.

Aircraft 4D Trajectory Prediction in Civil Aviation
Aircraft four dimensional (4D, including longitude, latitude, altitude and time) trajectory prediction is a key technology for existing automation systems and the basis for future trajectory-based operations. The trajectory prediction is the process of estimating the future states of the aircraft based on the current aircraft state, estimation of the pilot and controller intent, expected environmental conditions, and computer models of aircraft performance and procedures.

Aircraft Boarding Strategies
The pandemic caused by the COVID-19 virus (SARS-CoV-2) has been a source of concern for airlines regarding safe flight environments. The main reason is that infected people may experience no symptoms. Nevertheless, they may have high viral loads and spread the disease. To ensure the safety of passengers concerning virus propagation, such as COVID-19, and keep the turnaround time at low levels, airlines should seek efficient aircraft boarding strategies in terms of both physical distancing and boarding times.
