What is the Va maneuvering speed?

• A. 200
• B. 230
• C. 240
• D. 260

Answer: (C)

Va is the speed at which full, abrupt control inputs can produce the airplane’s limit load factor without exceeding structural limits. It’s tied to weight and configuration—the heavier the airplane, the higher Va. For the ERJ 175, at typical operating weights, Va is about 240 knots. This means that at or below 240 knots you can move the controls fully and expect the airplane to stay within its structural limits; above that speed, the same abrupt inputs could overstress the airframe. That’s why 240 knots is the correct figure. The other speeds don’t represent the maneuvering speed for this aircraft at its present configuration; Va isn’t stall speed, cruise speed, or a fixed exhaustively safe speed—it’s a load-management speed that increases with weight.
