Transport Canada won't even consider an AP unless it can do at least 25kt head, 15kt cross & 10kt tail. . .BTW watch out for "tower winds" from airfields in the US Mid-West equipped with Low Level Wind Shear sytems - they give out an average out of the LLWS sensors that can be almost an order of magnitude lower than the IRU shows on the approach. Their sensors are only at about 3m as opposed to the old ICAO 10m tower anemometer.
