In maintenance-required lighting configuration, which lights must be ON?

• A. Landing light and/or taxi light: ON
• B. Anti-collision: ON
• C. Position: ON
• D. Searchlight: ON

Answer: (A)

The situation is focused on ground operations for a maintenance-required status. In this configuration, the lights that must be on are the landing light and/or taxi light, because they directly support ground visibility and safe movement during maintenance activities. Having the landing or taxi light on helps illuminate the ramp area and makes the aircraft more conspicuous to personnel working nearby. Anti-collision lights are meant to enhance in-flight conspicuity, which isn’t the primary concern in a maintenance scenario. Position lights (navigation lights) are required for certain flight conditions but aren’t mandated specifically by this ground-maintenance configuration. A searchlight isn’t needed for routine maintenance operations.
