Under Lower than Standard Takeoff Minima, what is required when TDZ RVR is 1600?

• A. TDZ RVR 1600 requires HIRL or Operative CL Lights or RCLM or Adequate Visual Reference
• B. TDZ RVR 1600 requires only RCLM
• C. TDZ RVR 1600 requires only HIRL
• D. TDZ RVR 1600 requires day-night lighting all time

Answer: (A)

Lower than standard takeoff minima require a visible runway reference when operating with reduced visibility. If the touchdown zone RVR is 1600 feet, you must have at least one of these cues available to provide that reference: high-intensity runway lights, operational runway centerline lights, runway centerline markings, or an Adequate Visual Reference to the runway environment. This ensures the crew can confidently identify the runway and maintain situational awareness during the takeoff despite the lower RVR. The other options don’t fully meet the requirement because they omit one of these essential cues, and requiring lighting all day isn’t how LT takeoff minima are applied.
