At KNDZ OPS or civilian airports, what is the required anti-collision and position lighting configuration?

• A. Anti-collision ON; Position: as req
• B. Anti-collision OFF; Position: as req
• C. Anti-collision ON; Position: ON
• D. Anti-collision ON; Position: OFF

Answer: (A)

The main idea is how the aircraft’s lights are used to stay visible to others. Anti-collision lights are required whenever the engine is running or the aircraft is in flight, so you have them on to help others see you. Position (navigation) lights, on the other hand, are not a constant requirement all the time; they’re used when the rules call for them—typically from sunset to sunrise or in reduced visibility—so they’re set “as required” by the time of day and conditions. At KNDZ OPS or civilian airports, this means the anti-collision lights should be ON, and the position lights should be ON only when the situation calls for them. That combination keeps you visible in all normal operating scenarios without forcing navigation lights when they aren’t required.
