What are the CAT II lowest minimums for runway operations?

The CAT II lowest minimums for runway operations, which are critical for precision approach and landing, are set to enhance safety during low visibility conditions. The correct answer reflects the standards established for CAT II operations, which allow for a decision height of 100 feet and a runway visual range (RVR) of 1200 feet.

These minimums enable aircraft to land with a high degree of precision even in challenging visibility, as CAT II approaches utilize advanced aircraft systems and ground guidance to ensure safe landings. The decision height indicates the altitude at which a pilot must have visual reference to the runway to continue the approach; if that reference is not attained, the pilot is required to execute a go-around.

The specified RVR provides an additional measure of visibility; having a minimum of 1200 feet means that the pilots should be able to see the necessary visual cues (such as runway lights) that confirm the landing environment.

Understanding these parameters is essential for pilots and aviation personnel as they plan and conduct operations under low-visibility conditions, ensuring compliance with safety regulations and optimal performance of aircraft systems.
