What is the Minimum Decision Altitude (MDA) requirement for a VOR approach?

The Minimum Decision Altitude (MDA) requirement for a VOR approach is primarily concerned with ensuring that a pilot has adequate visibility of both the approach path and the runway environment upon reaching the MDA. This allows for a safe descent and landing while maintaining required visual references.

When a pilot reaches the MDA, they must ensure they have sufficient visual references to safely continue to the runway. If the required visibility and runway environment are not visible, the pilot must execute a missed approach. Therefore, recognizing both MDA and the runway environment is critical for making safe landing decisions during the approach phase.

In contrast, merely having ground visibility (as in option A) is insufficient if the pilot cannot see the runway environment. The Minimum Safe Altitude (MSA) and Standard Terminal Arrival Route (STAR) do not relate directly to the MDA specifically for VOR approaches; they serve different purposes regarding safe altitude and traffic routing in the terminal area.
