C079 lowest takeoff visibility and equipment. What is the required minimum and equipment?

• A. 500 RVR with HIRL, operative runway centerline lights, and a minimum of 2 RVR reporting systems
• B. 500 RVR with HIRL only
• C. 300 RVR with HUD in the Global Express
• D. 400 RVR with CL lights and 1 RVR system

Answer: (A)

In Part 135 operations, the lowest takeoff visibility you may use is 500 ft RVR, but you must have specific equipment in operation to rely on that minimum. The runway must have high-intensity runway lights and those lights on the runway centerline must be operative. In addition, there must be at least two RVR reporting systems available for the runway. The redundancy of two separate RVR sensors provides reliable and cross-checked visibility data, which is essential when operating at such a low minimum. That’s why a setup with only HIRL and no second RVR system isn’t sufficient, and a lower minimum like 300 RVR isn’t considered standard without the appropriate equipment and approvals. The combination described in the first option matches the required minimums for takeoff at 500 RVR: 500 ft RVR, HIRL, operative centerline lights, and a minimum of two RVR reporting systems.
