Which statement about airspeed limits for extended devices is true?

• A. Landing Light extended has a maximum airspeed of 180 knots.
• B. Search Light extended has a maximum airspeed of 200 knots.
• C. Open Gunner's Window has a maximum airspeed of 160 knots.
• D. Landing Light extended has a maximum airspeed of 130 knots.

Answer: (A)

Extending external devices changes the helicopter’s aerodynamics and loads. The airspeed must be kept below a published limit to prevent over-stressing the extension hardware and to maintain safe control with the device out. For the UH-60, the landing light when extended has a maximum airspeed of 180 knots, which is the published limit for that configuration. The other figures pertain to different extended devices or are not the official limits, so they don’t match the approved operating envelope.
