The EFCS will not maintain more than VaMAX, even if sidestick is full aft. Which statement is true?

The EFCS will not maintain more than VaMAX, even if sidestick is full aft. Which statement is true?

• A. True
• B. False
• C. Not specified
• D. Always

Answer: (A)

The key idea is how the FBW EFCS protects the airframe by enforcing maneuvering limits. VaMAX represents the speed/condition where the airplane can be maneuvered without exceeding structural load limits. The EFCS uses protection logic that prevents commands from producing a load beyond that envelope. When you push the sidestick fully aft, you’re requesting maximum nose-up maneuver, but the control laws cap the commanded load to what VaMAX allows. If following the full aft input would exceed structural limits, the system saturates the response and won’t maintain a higher maneuvering load. So the airplane won’t be commanded to exceed VaMAX, making the statement true.
