For a Category C airplane, low visibility take-off operator approval from the Authority is needed when RVR is less than what distance?

In the context of aviation regulations, specifically for Category C aircraft operations, visibility requirements are critical for ensuring safety during take-off under low visibility conditions. Category C airplanes are typically designed for operations that can be conducted in lower visibility scenarios, but they still require specific regulatory approvals depending on the visibility criteria established by the aviation authority.

When the runway visual range (RVR) falls below 150 meters, the operator must have obtained approval from the relevant aviation authority for low visibility take-off operations. This requirement is in place to ensure that pilots have the appropriate training and operational procedures in place to manage the risks associated with low visibility scenarios effectively.

The threshold of 150 meters reflects a balance between operational safety and the capabilities of Category C aircraft, allowing them to operate safely while maintaining high safety standards. This regulatory requirement emphasizes the importance of proper training and protocol adherence for crews operating in low visibility conditions, ensuring that safety remains a top priority.
