It's difficult because any minute amount of wind will affect the final results, and you don't have the full wind profile over the entire aircraft to compensate for it. Easier and safer to track what's on board and calculate the a/c performance based on that + margins.

- mannykannot 4y agoI take your point; I have no idea of the magnitude of this effect in proportion to the total weight. I do wonder if a combination of the airspeed instrument readings, their fluctuation, and fluctuations in the measured weight could be used to estimate the influence of the wind (an application for machine learning?) but even so, that would mean that it would no longer be a simple solution.
- dclowd9901 4y agoWhat I’m talking about is just a way to provide something besides a pilot’s hunch to compare against weight data from flight crews. If it was so windy that it would catastrophically throw off the comparison, I doubt they’d even let the planes take off.
- nradov 4y agoThat's not how it works. Airliners can safely take off into strong headwinds. A wind blowing across the wings will produce significant lift. In theory it might be possible to compensate for that effect, but in practice it's just too much hassle.
