What is the maximum crosswind limit for CAT II operations?

The maximum crosswind limit for CAT II operations on the ERJ 170/175 is 12 knots. This limitation is crucial for ensuring safe landing conditions under specific visibility and approach scenarios associated with CAT II operations, which involve reduced decision height and lower visibility thresholds. Exceeding this crosswind limit could compromise control of the aircraft during the critical phases of landing, particularly on a precision approach.

Operating within this limitation helps to mitigate the risks associated with crosswinds, which can affect the aircraft's stability and handling characteristics. The specific threshold is established based on performance data and regulatory standards that optimize safety during low-visibility conditions. Understanding and adhering to these limitations is essential for flight crew competency and safety in operations involving Category II landings.
