• Feeding real‑time angle‑of‑attack data to the stall warning and protection systems.
  
  

• Supplying inputs to the Fly‑By‑Wire flight control computers for envelope protection and flight envelope management.
  
  

• Driving cockpit Aoa indicators and multi‑function displays to keep pilots informed of approaching stall conditions.
  
  

• Enabling automated wind shear detection and alert functions by monitoring rapid changes in angle of attack.

• What does the Angle of Attack Sensor measure?

It measures the angle between the wing’s chord line and the relative airflow, which is critical for stall detection and flight control.

• Why is anti‑icing important for this sensor?
  

Moisture can accumulate and freeze on the sensor vane, causing erroneous readings; the built‑in heater prevents ice buildup to ensure accuracy.

• What happens if one of the redundant channels fails?

The second, independent channel continues to supply angle‑of‑attack data, allowing flight control systems and cockpit displays to operate without interruption.
