What is the minimum descent altitude (MDA) for a category C aircraft during a circling LOC 32 approach at Dothan, AL?

The minimum descent altitude (MDA) for a Category C aircraft during a circling approach is primarily determined by the specific approach procedure as outlined in the appropriate approach charts. In this case, for a circling LOC 32 approach at Dothan, AL, the MDA is typically set to ensure safe maneuvering around the airport while considering the specific dimensions of the airspace and the performance characteristics of category C aircraft.

Category C aircraft are defined by their approach speeds, which influence the requirements for safe operation during the circling phase. The MDA is established to maintain a safe altitude above the highest terrain or obstacle within the circling area. In this scenario, the established MDA for Category C during the LOC 32 approach is 860 feet MSL, as noted in the approach documentation.

Using the correct MDA ensures that pilots maintain a safe altitude while circling to land, which is critical for avoiding obstacles and ensuring a safe transition to the landing phase. Therefore, the option detailing 860 feet MSL is accurate given the specific circling procedure and the related approach criteria for Category C aircraft at Dothan.
