A hot air balloon usually carries enough liquefied petroleum gas or propane to fly for two hours, but some factors will also affect the flight duration, such as temperature, wind speed, hanging basket weight (including passengers) and the specific flight time of the day.

Your dream-tuition 16000- 18000 yuan.

At present, hot air balloon is still an "aristocratic" sport in China. Because the cost of hot air balloon is relatively high, the cost of flying and the cost of learning to obtain a flight license are also relatively high, and the number of people participating in this sport in China is still relatively small. There are about 200 balloons in China, and 200 people have obtained the hot air balloon flight license issued by civil aviation. Not many enthusiasts buy hot air balloons for amateur flights. Balloons are usually rented from flying clubs or released during training, competitions and business activities. At present, the seven-type hot air balloon widely used in China has a maximum diameter of17m, a height of 23m, a volume of about 2180m3 and a maximum flying height of 7000m. However, as long as you have money, it is not too difficult to take a hot air balloon ride in China. Need to find a formal professional hot air balloon club to sign up. First of all, you need to have a routine physical examination and a civil aviation physical examination. After about 20 days of theoretical study and flight practice, you can reach the level of independent solo flight, and then you can apply for a civil aviation driver's license for hot air balloons by passing the civil aviation inspector exam. Of course, the tuition fee is about 16000- 18000 yuan. After the completion of the course, if you still fly in the professional club, you still have to pay a certain flight fee for each flight; The cost of experiencing a flight is about 400-500 yuan per hour; If you want to buy a hot air balloon and engage in flight activities in your own area, you need to go to the air traffic control department for approval and declaration of flight airspace. It costs about 76 thousand yuan to buy a standard hot air balloon. In some tourist attractions in China, there is also a kind of "tethered flight", that is, a hot air balloon that does not fly away. Although it can only rise to the height of 30 to 50 meters, it can still initially experience the feeling of "ruling the world" when hot air balloons fly.
