skiesful, Re “Your company limits are more conservative than the manufacturers demonstrated limits”. Your statement might be assuming too much; just as individuals lack accurate guidance on wind measurement, so do many operators on how to apply demonstrated limits – what do they (certification regulation, manufacturer, management, and the demonstrated value) actually mean.
You appear to be the first to consider wind strength, whereas previous posts only considered direction.
It’s continually surprising how human thought focus on just one aspect of a question; crosswind component is a function of direction and strength.
Slide rule accuracy in determining wind direction is of little value where the accuracy of wind direction might only be +/- 5 deg, or even greater error due to averaging methods.
Similarly, wind strength might be in error by +/- 10 kts; and then there are gusts.
Simple rules of thumb are valuable aids for determining ‘ball-park’ values which contribute to the assessment and judgment of the conditions and crosschecking other estimates or ‘computed’ values (computers rarely assess or judge). There are many other aspects that should be considered in association with a crosswind, e.g. runway condition (dry / wet / icy), runway width, aircraft configuration (and MEL), availability of max reverse (tail engines), landing weight in proportion to the maximum allowed for the runway length (braking effectiveness in a crosswind).
Operations in crosswind require careful thought; wind direction, speed and gusts, the components both across and along the runway, and particularly any tailwind component.
Remember that the component along the runway may be factored (tailwind 150%) when calculating landing distance, the result includes a margin for error.
What margins for error are there in distances across the runway in crosswind operations?
Are these included in operators limits or are they left to the judgment of individual pilots?
What would be a suitable margin (with / without gusts); would this be a proportion of the crosswind component or something else?
