In formation lost comms lighting configuration, which lights are ON or OFF as specified?

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

Answer: (B)

In a formation with lost communications, the goal is to stay clearly visible to the lead and other aircraft while avoiding signal confusion. Turning off the anti-collision lights helps reduce potential misinterpretation of flashing strobes in a tight formation. Keeping the position lights on provides essential orientation cues—the red on the left and green on the right let others gauge your relative position and direction. The searchlight remains on to boost visibility in low light, aiding both obstacle discovery and quick visual contact with the lead aircraft. Finally, having the landing light and taxi lights on increases ground visibility and conspicuity during approach, landing, and taxiing, which is especially important when you can’t rely on radio guidance. This combination effectively maintains formation awareness and safety under lost comms conditions.
