Which computer is responsible for windshear detection?

The Flight Augmentation Computer (FAC) plays a crucial role in windshear detection on the A320. This computer is part of the aircraft's flight control system and is specifically tasked with managing functions related to lateral and vertical flight. Among its various responsibilities, the FAC processes data from the aircraft's sensors to detect environmental conditions, including windshear.

Windshear can pose significant risks during takeoff and landing, and timely detection is essential for pilot awareness and routine flight safety. The FAC utilizes input from other systems and sensors to analyze changes in wind conditions, enabling it to provide warnings to the flight crew when necessary. This function is critical, especially in areas where windshear phenomena are more prevalent, allowing for prompt corrective actions during critical phases of flight.

The other systems, while integral to the aircraft's functioning, have distinctly different roles. The ADIRs (Air Data Inertial Reference Units) provide raw data regarding the aircraft’s airspeed, altitude, and attitude but do not specifically handle windshear detection. The SEC (Spoilers Electronic Control) manages the aircraft's spoiler systems primarily for roll control and ground spoilers, while the ELAC (Electronic Flight Control Computer) manages various flight control laws. However, it is
