The basic knowledge of aircraft includes the following aspects:
1. Aircraft structure: Aircraft are usually composed of fuselage, wings, tail, landing gear and other parts. The fuselage is the main structure of the aircraft, carrying passengers and cargo; the wings generate lift to provide flight stability; the tail is used to balance the aircraft; and the landing gear is used to support the aircraft during take-off and landing.
2. Principle of flight: The lift of the aircraft is based on Bernoulli's principle and Newton's third law. The air flows faster on the upper surface of the wing with less pressure, while the lower surface flows slowly and exerts greater pressure, generating lift. At the same time, the aircraft generates thrust through jet propulsion or spiral-dyed propulsion, overcomes the positive force, and achieves flight.
3. Flight control: The aircraft controls the flight attitude and direction through the control surfaces (such as aions, lift rudder, rudder, etc.). The ailer controls the roll (the aircraft rotates around the long axis), the rudder controls the climb and descent, and the rudder controls the turning.
4. Flight instruments: The aircraft is equipped with various instruments to monitor the flight status and provide navigation information. Common flight instruments include altimeters, speedometers, compasses, artificial horizers, etc., as well as modern digital display and navigation systems.
5. Flight safety: The aircraft is equipped with safety devices, such as fire protection systems, evacuation slides, emergency slides, etc., to ensure safety in flight. In addition, pilots ensure the safety of operating aircraft through strict training and examination.
