Private jet refers to a privately owned aircraft, which is used to facilitate personal use or business trips of individuals and their entourage, and also reflects the owner's identity. The concept of "private jet" should be from the point of view of the property owner, which is different from the traditional aircraft that are owned by airlines or enterprises. All available airworthiness aircraft (helicopters, fixed-wing aircraft) on the market can be included in the category of private jets, ranging from ultra-light aircraft worth more than 100,000 yuan to Boeing 747 and Airbus A380 worth hundreds of millions of yuan. As long as the property right of an airplane is privately owned, it can be called a private airplane.
