What landing minimums apply for a 14 CFR Part 91 operator using a category C aircraft during a circling LOC 32 approach at a speed of 120 knots?

For a 14 CFR Part 91 operator conducting a circling approach, the minimums are determined by the aircraft category and the approach being flown. In this scenario, the operator is using a Category C aircraft, which typically has a maximum approach speed of 120 knots.

During a circling approach, the visibility and minimum descent altitude (MDA) requirements are higher than those for straight-in approaches. For Category C aircraft, the standard MDA for a circling approach at an airport with a specific approach plate is generally set at 860 feet MSL, and the associated visibility minimum is 1.5 statute miles (SM).

Thus, selecting MDA of 860 feet and the visibility of 1 and 1/2 SM aligns with the requirements for a circling approach for a Category C aircraft operating at the stated speed. This ensures that the pilot has adequate visibility to maintain visual reference and execute the circling maneuver safely.

Understanding the specific altitude and visibility requirements for different categories of aircraft during different types of approaches is crucial for safe operations under the regulations laid out in Part 91.
