Development of YSFlight began in 1998 as a solo project by Soji Yamakawa. He first started working on the simulator as a school project; afterwards, it was further developed into a flight aid for others who need assistance in understanding aircraft flight instrumentation and flight physics. Initially designed to be run by lower-end computers, the flight simulator began to implement more updated graphical features with its 2015 release. On August 19, 2022, Yamakawa published YSFlight's source code and assets to
GitHub under the
BSD-3-Clause license, while stating that he intends to continue the simulator's development. ==Features==
