At what airspeed is AGCAS disabled?

• A. When CAS is below 150 knots
• B. When CAS is below 120 knots
• C. When CAS is below the required 2G pull-up speed
• D. When CAS is below 100 knots

Answer: (C)

The correct answer is the condition of AGCAS (Automatic Ground Collision Avoidance System) being disabled when the indicated airspeed (CAS) is below the required 2G pull-up speed. This specific airspeed is critical because AGCAS is designed to assist in preventing ground collisions by initiating a pull-up maneuver when the aircraft is in a potentially dangerous flight condition. At airspeeds below the required 2G pull-up speed, the aircraft may not have sufficient aerodynamic capability to execute a safe pull-up maneuver. The 2G requirement indicates that the aircraft needs to be able to generate enough lift and maintain control during the pull-up, which is not feasible at lower speeds. Therefore, the AGCAS system disables itself to avoid executing a maneuver that could increase the risk of a collision with the ground due to inadequate performance. Understanding the limitations of the aircraft's capabilities at varied speeds is crucial for safe flight operations. AGCAS is engineered to function within certain parameters, and this specific criterion is part of that safety framework, ensuring that the system activates only when the aircraft can effectively maneuver to prevent a collision.
