Avionics refers to the electronic systems used in aircraft, spacecraft, and satellites. These systems include navigation, communication, and monitoring devices that help pilots and crew operate the vehicle safely and efficiently. For example, GPS technology allows pilots to determine their exact location, while radar systems help detect other aircraft and obstacles. In addition to navigation and communication, avionics also encompasses flight control systems that assist in managing the aircraft's movements. Modern avionics can even include advanced features like autopilot systems, which can automatically control the flight path, making flying safer and more precise for both commercial and military aviation.
