What is the maximum airspeed for the OH-58D Kiowa Warrior?

• A. 105 knots
• B. 110 knots
• C. 115 knots
• D. 100 knots

Answer: (B)

The maximum airspeed is defined by the never-exceed speed (Vne) for the helicopter, the speed you must not go past to protect the airframe and its systems. For the OH-58D Kiowa Warrior, that published limit is 110 knots. This value is chosen because beyond it the aircraft experiences higher structural loads, rotor and tail-rotor performance margins shrink, and aerodynamic effects like rotor Mach limits and controllability issues become more likely. Sticking to 110 knots keeps vibration, blade loads, and tail-rotor authority within safe, certified boundaries so you maintain reliable control. Speeds like 100 or 105 knots are safely below the limit, and 115 knots would exceed it, risking structural or control problems.
