Which device provides visual indicators for the landing gear’s status?

The landing gear position indicator is specifically designed to provide visual cues regarding the status of the landing gear. This device displays whether the landing gear is in the extended (down) or retracted (up) position, which is crucial for pilots to ensure safe landing and takeoff procedures. By giving a clear visual representation of the landing gear's status, the indicator helps pilots make immediate decisions about the gear's configuration before landing or during emergency situations.

Other options, while they relate to various aircraft systems, do not serve the specific purpose of indicating the landing gear’s position. The hydraulic system gauge measures the pressure of the hydraulic fluid, which could indirectly relate to landing gear operation but does not provide specific status information. The flight management system manages navigation and flight planning but does not show landing gear status. The speed indicator shows the aircraft’s speed but is unrelated to the gear position itself.
