This is a flight simulation business game. The simulated flight part means that players need to control acceleration, deceleration, speed brakes, etc. through keyboard keys to control the aircraft (takeoff, landing, flight); while the business part requires the use of various different aircraft (agricultural, freight, passenger) to complete the transportation of goods, Accumulate funds through tasks such as transporting passengers and farming, and buy better aircraft to run your own flying empire; when you have enough funds, you can purchase excess aircraft and add them to the automatic transportation system, which will automatically make money for you. Everything in the game is free. You can choose free flight routes, any towns, mining areas, factories and other places to summarize the needs of goods and passengers. Larger aircraft can carry more cargo passengers, but there are runway issues in some small towns to consider.
