This advisory circular (AC) provides an acceptable means, but not the only means, for obtaining and maintaining authorization of operations in Category (CAT) I, CAT II, and CAT III landing weather minima and instrument flight rules (IFR) lower-than-standard takeoff minima. This AC does not change, add, or delete regulatory requirements or authorize deviations from regulatory requirements. This AC addresses the operational authorizations formerly published in AC 120-28, Criteria for Approval of Category III Weather Minima for Takeoff, Landing, and Rollout, and AC 120-29, Criteria for Approval of Category I and Category II Weather Minima for Approach, and any subsequent developments.
