What is the minimum visibility required for a Standard Instrument Rating when using a non-precision approach?

When executing a non-precision approach, the minimum visibility requirement is indeed expressed as 200 feet horizontal visibility or 1/2 statute mile. This visibility standard helps ensure that pilots can adequately see and identify the runway environment and safely execute the approach.

In non-precision approaches, unlike precision approaches, there's no electronic glide slope information provided to assist with vertical guidance; therefore, pilots rely on visual references related to horizontal visibility. The requirement of 200-1/2 allows pilots to navigate and maintain an adequate approach path while offering sufficient ground references to establish visual contact with the airport.

The other options represent visibility requirements that do not adhere to the specific regulations and standards for non-precision approaches, making them unsuitable choices. Understanding these visibility requirements is essential for flight safety and effective navigation during instrument approaches.
