Rotorcraft in the context of "Boeing"

An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, drones, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air."

The human activity that surrounds aircraft is called aviation. The science of aviation, including designing and building aircraft, is called aeronautics. Crewed aircraft are flown by an onboard pilot, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion (if any), usage and others.

A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of short take-off and landing (STOL) or short take-off and vertical landing (STOVL) aircraft cannot perform without a runway.

The Focke-Wulf Fw 61 was the first successful, practical, and fully controllable helicopter in 1936, while in 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production. Starting in 1939 and through 1943, Igor Sikorsky worked on the development of the VS-300, which over four iterations, became the basis for modern helicopters with a single main rotor and a single tail rotor.

A carrier air wing (abbreviated CVW) is an operational naval aviation organization composed of several aircraft squadrons and detachments of various types of fixed-wing and rotary-wing aircraft. Organized, equipped and trained to conduct modern US Navy carrier air operations while embarked aboard aircraft carriers, the various squadrons in an air wing have different but complementary (and sometimes overlapping) missions, and provide most of the striking power and electronic warfare capabilities of a carrier battle group (CVBG). While the CVBG term is still used by other nations, the CVBG in US parlance is now known as a carrier strike group (CSG).

Until 1963, Carrier Air Wings were known as Carrier Air Groups (CVGs). Carrier Air Wings are what the United States Air Force would call "composite" wings, and should not be confused with U.S. Navy Type Wings (such as Strike Fighter Wing Atlantic), which are primarily administrative and training commands composed of squadrons of the same type of carrier-based aircraft when not deployed. The United States Marine Corps equivalent command-level organization to a CVW is the Marine Aircraft Group (MAG). However, MAGs are shore-based (with sea-based capability) and may contain any combination of aircraft squadrons and aviation support units. Carrier Air Wings integrate closely with their assigned aircraft carriers, forming a "carrier/air wing team" that trains and deploys together. There are currently nine U.S. Navy Carrier Air Wings; four of the wing commanders and their staffs are based at Naval Air Station Oceana, Virginia, four are based at Naval Air Station Lemoore, California, and one is aboard Marine Corps Air Station Iwakuni, Japan. The squadrons which make up each wing are based at various bases in the U.S. with their respective Type Wing Commanders with the exception of those squadrons assigned to the Japan based airwing which are based at Marine Corps Air Station Iwakuni (fixed wing squadrons) and Naval Air Facility Atsugi, Japan (helicopters).

A military aircraft is any fixed-wing or rotary-wing aircraft that is operated by a legal or insurrectionary military of any type. Some military aircraft engage directly in aerial warfare, while others take on support roles:

• Combat aircraft, such as fighters and bombers, are designed to destroy enemy equipment or personnel using their own ordnance. Combat aircraft are typically developed and procured only by military forces.
• Non-combat aircraft, such as transports and tankers, are not designed for combat as their primary function but may carry weapons for self-defense. These mainly operate in support roles, and may be developed by either military forces or civilian organizations.

An unmanned aerial vehicle (UAV) or unmanned aircraft system (UAS), commonly known as a drone, is an aircraft with no human pilot, crew, or passengers on board, but rather is controlled remotely or is autonomous. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications. These include aerial photography, area coverage, precision agriculture, forest fire monitoring, river monitoring, environmental monitoring, weather observation, policing and surveillance, infrastructure inspections, smuggling, product deliveries, entertainment and drone racing.

A fixed-wing aircraft is a heavier-than-air aircraft, such as an airplane, which is capable of flight using aerodynamic lift. Fixed-wing aircraft are distinct from rotary-wing aircraft (in which a rotor mounted on a spinning shaft generates lift), and ornithopters (in which the wings oscillate to generate lift). The wings of a fixed-wing aircraft are not necessarily rigid; kites, hang gliders, variable-sweep wing aircraft, and airplanes that use wing morphing are all classified as fixed wing.

Gliding fixed-wing aircraft, including free-flying gliders and tethered kites, can use moving air to gain altitude. Powered fixed-wing aircraft (airplanes) that gain forward thrust from an engine include powered paragliders, powered hang gliders and ground effect vehicles. Most fixed-wing aircraft are operated by a pilot, but some are unmanned or controlled remotely or are completely autonomous (no remote pilot).

Police aviation is the use of aircraft in police operations. Police services commonly use aircraft for traffic control, ground support, search and rescue, high-speed car pursuits, observation, air patrol and control of large-scale public events and/or public order incidents. They may employ rotary-wing aircraft, fixed-wing aircraft, nonrigid-wing aircraft or lighter-than-air aircraft. In some major cities, police rotary-wing aircraft are also used as air transportation for personnel belonging to police tactical units. In large, sparsely populated areas, fixed-wing aircraft are sometimes used to transport personnel and equipment.
