What procedure should a pilot follow when circling to land in a Category B airplane but flying 5 knots faster than the maximum specified speed?

When flying a Category B airplane while exceeding the maximum specified speed for that category, it is critical to apply the appropriate approach minimums for broader categories, such as Category C. The rationale behind using Category C minimums is based on the aircraft's performance characteristics and the fact that flying above the maximum speed for a category places the aircraft in a different set of operational parameters.

Category B aircraft have specific speed requirements during approach and landing, with the maximum speed limit being a critical factor to maintain safety and efficient handling. When an aircraft operates outside of these limits, it may not perform as expected, leading to decreased maneuverability and potentially increasing the risk during landing maneuvers. By transitioning to the approach minimums designated for Category C, which accounts for faster aircraft, adequate safety margins are maintained, ensuring that the approach and landing can be conducted effectively despite the speed differential.

This approach ensures that any additional requirements or considerations pertinent to the higher performance levels of Category C are adhered to, thus mitigating risk and ensuring the approach remains within safe operating conditions. Choosing option C aligns with these safety and performance principles when navigating the landing phase at speeds beyond what is prescribed for Category B.
