 Aircraft (Aircraft, plane), with a wing and a means or with the engine, by its own power of flight in the atmosphere heavier than air aircraft. And civilian aircraft, widely used not only to transport and scientific research, or an important weapon in the modern military, it is divided into civil and military aircraft. In addition to civil aircraft other than aircraft and transport planes and agriculture machines, forest protection machine, aerial machine, medical care machine, visit the machine, executive jets, sports machine, experimental and research aircraft, weather machine, stunts machines, law enforcement and so on. 
 Component parts of the aircraft but also by the shape, number and relative position of the classification. By the number of wings can be divided into monoplane, biplane and multi-wing aircraft. Relative to the fuselage at the wing position, can be divided into the wing, the wing and upper wing aircraft. Plane by the wing shape, can be divided into straight-wing aircraft, swept wing aircraft delta wing forward swept wing aircraft and aircraft. According to the location and the availability of horizontal tail horizontal stabilizer, can be divided into the normal layout of the aircraft (wing, horizontal tail in later), canard aircraft (with a small wing before the fuselage) and the tailless aircraft (no horizontal stabilizer); normal layout of the aircraft has a single tail, double tail, multi-vertical tail and V-tail and other types. According to the type of propulsion, propeller aircraft and jets can be divided into; by the type of engine can be divided into piston aircraft, turboprop and jet aircraft; by the number of engines, the aircraft can be divided into single, double Development aircraft and multiple aircraft. According to the type landing gear can be divided into land-based aircraft, seaplanes and amphibious aircraft. But also by the flight performance of classification: according to the flight speed, can be divided into subsonic aircraft, supersonic aircraft and hypersonic aircraft. Voyage by plane can be divided into short-range aircraft, medium-range aircraft and long-range aircraft. 
 Cockpit of modern aircraft flight control for drivers to use devices typically include: the main control device: the steering column or steering wheel and rudder pedals. In some aircraft with fly-system, the control stick or steering wheel have been simplified into the side of the joystick in the driver. Auxiliary control device: the flap handle, trim buttons, speed brake handle. 
 With the development of electronic technology, flight control devices in the form of fundamental changes have taken place. In large aircraft, the traditional mechanical control system is gradually being more advanced control system replaced by telex, computer systems become fully involved in flight control systems, such as driver's operation is no longer directly control the aircraft movements, and more such as motion commands issued to the aircraft. Because some of the aircraft control system by telex to cancel the original steering column or steering wheel and other control devices and to the side bar, the cockpit of the space appears more relaxed than in the past, some drivers said the cockpit such as " Flight Office. " 
 And compared with other modes of transport, the aircraft has many advantages: speed. Current jet speed of 900 km or so. High mobility. Aircraft flying from mountains, rivers, deserts, ocean barrier, and according to the customer, supply to increase the number of flights at any time. Safe and comfortable. According to ICAO statistics, civil aviation passenger-kilometers per million in the number of deaths was 0.04 people, the ordinary mode of transport accident deaths of several to several one-tenth of one percent, and rail traffic tied for the most secure mode of transport. 
 However, as a transport aircraft also have their own limitations: expensive. Whether flying the aircraft itself or the consumption of oil relative to other transport means are more expensive. Affected by weather conditions. Although the vast majority of aviation technology has been able to adapt to weather conditions, but the more serious of the wind, rain, snow, fog and other weather conditions continue to affect the safety of aircraft taking off and landing. Landing site is limited. Aircraft must take off and land at the airport, a city of at most a few airports, and airport clearance constraints by the surrounding scattered in the suburbs. As from the airport to the city transit often requires a long process, which provides high-speed trains to 800 kilometers away from the intercity transportation market space. 
 Therefore, only applicable to aircraft weight, time-urgent, can not too close range transport. Dangerous. Although the airliner passenger km per million the number of deaths is far lower than other transportation modes, but critics say the aircraft itself, the journey than the other modes are also long, so this value is low. In some data on the plane is not particularly safe.
