The test to establish the ’demonstrated’ crosswind requires landings on each end of a runway with a measured wind at 90 deg. Where the manufacturer does not find that the control of the aircraft was limiting then a ’demonstrated’ value is published. Rarely, where the limit is found then the limiting value is published.
For those aircraft in which I demonstrated the crosswind performance, the control limit was not found. However it was decided not to look for any higher crosswind as the general conditions were such that the approach turbulence would have detered most pilots – difficulty in lining up, and if that failed the repeated windshear warnings should have reinforced the need to go around / divert.
Yet some national authorities approve operators to fly to limits 5 kts above those flown by the manufacturer. Take care, treat demonstrated values in mature aircraft as limiting, use a lower personal limit, and reduce these values further on wet runways. Seek your management’s support in stating that the manufacturer's demonstrated values (or less) are the company’s never exceed limits and that decisions to divert at any time based on pilot judgement are not critisised.
The pilot is always the first at the scene of an accident and as such the first in the firing line, legal or otherwiswe.
