The Air Data System

The Air Data System

The Air Data System is a critical onboard equipment system for aircraft. It consists of various sensors that collect raw signals, an air data computer that processes these signals, and signal display devices. Primarily used to collect, compute, and process various atmospheric parameter information for aircraft, it serves as one of the vital signal sources for the entire aircraft. Systems interconnected with it include the flight control system, navigation system, fire control system, engine control system, air traffic control system, flight instrument display system, and warning system. Ensuring the accurate and efficient operation of these onboard systems requires guaranteeing their access to high-precision flight data and atmospheric parameters. The safety and stable flight of an aircraft are directly linked to the accuracy and reliability of atmospheric data. Precise atmospheric data plays a crucial role in enhancing flight maneuverability, safety, and economic efficiency. This book, grounded in the characteristics and current state of the Air Data System, begins with the fundamental principles of atmospheric data measurement to elucidate the key technologies and application methods of the Air Data System.
