What is the minimum required visibility for a non-precision approach at an alternate airport?

• A. 1 SM
• B. 2 SM
• C. 3 SM
• D. 1/2 SM

Answer: (B)

The minimum required visibility for a non-precision approach at an alternate airport is indeed 2 statute miles (SM). This requirement takes into account the additional challenges posed by non-precision approaches, which typically rely on lateral navigation aids rather than vertical guidance. Having a minimum visibility of 2 SM helps ensure that pilots have enough visibility to identify the runway environment and execute a safe landing. Regulations are set to enhance safety, particularly in situations where visibility may fluctuate due to weather conditions. The 2 SM requirement provides a buffer for pilots to navigate effectively during these approaches, allowing for better decision-making and a greater margin for safety as they prepare to land in potentially varying conditions. This is vital for maintaining situational awareness and ensuring that pilots can adequately see their approach path and align with the runway. Other visibility requirements that may be referenced, such as 1 SM or 1/2 SM, are typically not applicable to non-precision approaches at alternate airports due to the increased complexity and the higher safety standards needed for these situations.
