Maximum Landing Light Extension Speed?

Maximum Landing Light Extension Speed?

• A. 125 KIAS
• B. 120 KIAS
• C. 135 KIAS
• D. 140 KIAS

Answer: (C)

Extending a landing light exposes a fixed or retractable fixture to higher aerodynamic loads as speed increases. The light assembly and its deployment mechanism are designed to handle forward force and vibration up to a specific limit; exceeding that limit can cause structural damage, binding, or failure of the light or its wiring. For the MH-65E, the published maximum extension speed is 135 KIAS. Keeping the light deployment within this speed ensures the mechanism and fairing stay within their tested and safe load range, reducing the risk of damage or malfunction during operations. Other numbers don’t reflect the aircraft’s actual design limit. Deploy the landing light when you’re at or below 135 KIAS, and retract it if you anticipate speeds above that.
