It's hard to say. Civil self-taught flight is divided into civil aviation, small aircraft and helicopter driving. Civil aviation requires high academic qualifications, and then the physical examination is also very strict. It takes at least 3-4 years to enter the aviation school at your own expense. Small civil aircraft has a special aviation school, which requires low physical examination and academic qualifications, but it is not cheap, 400,000-500,000, and the time should be within 1 year. Civil helicopter driving is also about 400 thousand, but the time is not long, between six months and one year. There are many schools for civil helicopter driving training now. Flying takes hours, unlike studying in a car. The cost of flying a plane is very high. A small plane costs several thousand yuan an hour, and the cost of a civil airliner is higher, so the cost is beyond the affordability of ordinary people.
