What are the lowest CAT II minimums?

The lowest Category II (CAT II) minimums for instrument approaches are a Decision Height (DH) of 150 feet and a Runway Visual Range (RVR) of 1600 feet. These minimums indicate the lowest altitudes and visibility conditions under which an aircraft may execute a landing in low visibility conditions, ensuring that there is enough reference for the pilots to safely manage the landing.

In the CAT II approach, the aircraft is allowed to descend to a lower DH than a CAT I approach. The specific values of 150 feet and 1600 feet represent standards that have been established to ensure safety during such operations. Pilots and airline operations rely on these numbers when planning flights to airports with potential lower visibility, as this allows for a higher operational capability in adverse weather conditions.

Understanding these parameters is crucial for dispatchers and pilots alike, as they play a significant role in flight safety, operational planning, and compliance with aviation regulations.
