Airhart Aeronautics is developing a modern personal airplane with a fly-by-wire control system to make flying easier and safer. The goal is to reduce the complexity and danger of flying a small airplane, making it more accessible to people who don't currently fly. The system, called Airhart Assist, simplifies control of the airplane and prevents common mistakes that lead to accidents. The company aims to make flying as easy as driving a car, with a focus on safety and decision-making.
