Which device powers the AOA and stick shaker in an aircraft?

• A. AOA computer
• B. Altimeter
• C. Air data computer
• D. Flight control computer

Answer: (A)

The AOA (Angle of Attack) computer is responsible for powering both the AOA indication system and the stick shaker in an aircraft. The AOA is crucial for determining how close the aircraft is to a stall condition, and the system provides necessary data to the flight crew. The stick shaker provides tactile feedback to the pilot as a warning that the aircraft is approaching a stall, based on the AOA data processed by the computer. In this context, while the other devices have their own specific functions, they do not directly power the AOA and stick shaker. The altimeter primarily measures altitude, the air data computer processes various atmospheric data (such as temperature, pressure, and airspeed), and the flight control computer manages the aircraft's flight control surfaces based on various inputs. However, none of these directly manage or provide the AOA signals or operate the stick shaker, which is specifically the role of the AOA computer.
