What is the maximum crosswind limit for a CAT II approach?

The maximum crosswind limit for a Category II (CAT II) approach is generally set at 15 knots. This limit is established to ensure safe landing operations under instrument conditions, where pilots rely primarily on instruments rather than visual cues. CAT II approaches are characterized by lower visibility minimums and the use of advanced autopilot systems to facilitate landing in challenging conditions.

A crosswind exceeding this limit could impede the aircraft's ability to maintain the correct flight path during the critical phases of landing. Therefore, 15 knots is an industry-standard figure that helps maintain safety and control of the aircraft in these low-visibility situations. Understanding these limits is crucial for pilots to ensure compliance with operational safety standards during instrument landing system (ILS) approaches.
