What is the Turbulent Air Penetration Speed (Vra)?

• A. 210
• B. 230
• C. 225
• D. 240

Answer: (C)

Turbulent Air Penetration Speed (Vra) is the speed you fly in turbulent air to minimize gust loads and structural stress on the airframe. It’s a fixed indicated airspeed in the aircraft’s limitations that provides the best balance between control and safety when gusts are present. For this scenario, Vra is specified as 225 knots. That’s why the correct choice is 225. This speed sits below cruise to limit buffet and above stall protection, giving you a stable response in turbulence. The other numbers aren’t the defined Vra for this case, so they don’t represent the recommended turbulence-penetration speed.
