What is Va at maximum gross weight?

What is Va at maximum gross weight?

• A. Va is the maximum speed for full power in straight flight.
• B. Va is the minimum sink rate at maximum load.
• C. Va at maximum gross weight is the maneuvering speed at maximum takeoff weight; the maximum speed for full and abrupt control inputs without overstressing the airframe.
• D. Va is the stall speed in landing configuration.

Answer: (C)

Va is the speed at which the airframe can withstand full, abrupt control inputs without exceeding the design limit load, and it varies with gross weight. At maximum gross weight, the aircraft carries more load and can handle higher dynamic forces, so Va is higher. Therefore, Va at maximum gross weight is the maneuvering speed corresponding to the maximum takeoff weight—the highest speed at which you can apply full and abrupt control inputs without overstressing the airframe. This distinguishes Va from other speeds like maximum power in straight flight, minimum sink rate, or stall speed in landing configuration, which relate to different flight limits and conditions.
