At what RVR is a Category C airplane required to have low visibility take-off operator approval from the Authority?

A Category C airplane requires low visibility take-off operator approval from the relevant Authority when the Runway Visual Range (RVR) is at or below 150 meters. This requirement is grounded in safety protocols and regulations to ensure that aircraft operate under optimal visibility conditions, particularly during the critical phases of takeoff.

When the RVR is limited to 150 meters, it poses significant challenges for pilots regarding spatial awareness and decision-making during takeoff. Thus, the necessity for approval ensures that only those operators who have demonstrated adequate training, procedures, and equipment to manage these heightened risks are permitted to conduct operations under such low visibility conditions.

This threshold is set to maintain safety standards in aviation operations, as low visibility can drastically affect the pilot's ability to assess runway conditions and execute a safe takeoff. In summary, a Category C airplane is aligned with the regulatory requirements designed to enhance operational safety when visibility falls below 150 meters.
