Flight systems refer to the various technologies and components that enable an aircraft to operate safely and efficiently in the air. These systems include navigation, communication, and control mechanisms that help pilots manage the aircraft's flight path and performance. Key elements of flight systems are the avionics, which encompass electronic systems for flight management, and the autopilot, which assists in maintaining the aircraft's course. Additionally, flight systems incorporate safety features such as redundancy to ensure that if one system fails, others can take over. They also include flight data recorders, commonly known as "black boxes," which capture critical information during flights for analysis and safety improvements.
