It was widely understood that flying below maneuvering speed offered total protection from structural failure, allowing any control input to be safe.
Answer: False
A common misconception was that flight below maneuvering speed offered total structural protection. However, regulatory changes clarified that aggressive or multiple control inputs can still cause structural failure even at or below V<sub>A</sub>.
The destruction of American Airlines Flight 587 led to a CFR Final Rule that clarified limitations on control inputs even at or below design maneuvering speed.
Answer: True
Following the American Airlines Flight 587 accident, a CFR Final Rule was enacted to clarify that even at or below V<sub>A</sub>, certain aggressive or multiple control inputs could still lead to structural damage.
The CFR Final Rule permits single full control inputs across multiple airplane axes simultaneously, provided the aircraft is operating at or below the design maneuvering speed.
Answer: False
The CFR Final Rule explicitly states that single full control inputs across multiple airplane axes simultaneously are *not* permitted, even at or below V<sub>A</sub>, due to the risk of structural failure.
The maneuvering speed concept allows pilots to make multiple simultaneous control inputs across different axes without exceeding structural limits.
Answer: False
The maneuvering speed concept specifically applies to *single* full control deflections. Regulatory clarifications emphasize that multiple or simultaneous control inputs across different axes can still lead to structural failure, even below V<sub>A</sub>.

The design maneuvering speed (V<sub>A</sub>) must always be greater than the product of the stalling speed (V<sub>s</sub>) and the square root of the maximal allowed positive load factor (n).
Answer: False
V<sub>A</sub> cannot be *slower* than V<sub>s</sub>√n, but it does not *always* have to be *greater* than it. It can be equal to V<sub>s</sub>√n, in which case the aircraft is designed to stall before exceeding structural limits.
If a manufacturer chooses V<sub>A</sub> to be exactly V<sub>s</sub>√n, the aircraft is designed to stall before reaching its limiting aerodynamic load.
Answer: True
When V<sub>A</sub> is set precisely to V<sub>s</sub>√n, the aircraft's design ensures that it will stall in a nose-up pitching maneuver before the airframe experiences its maximum allowable aerodynamic load, thus protecting the airframe from excessive stress.
If V<sub>A</sub> is selected to be greater than V<sub>s</sub>√n, the aircraft's structure will always be protected from exceeding the limiting load during a maneuver.
Answer: False
If V<sub>A</sub> is greater than V<sub>s</sub>√n, the aircraft's structure *can* be subjected to loads exceeding the limiting load during a maneuver, unless the pilot actively checks or mitigates the maneuver to reduce the applied forces.
According to the source, what is the mathematical relationship defining the minimum design maneuvering speed (V<sub>A</sub>)?
