Spitoon, that has to be the most disingenuous remark ("a simple controller")...
Although I am trying to persuade other posters - with a degree of subtlety, I hope - that reliance on IR W/V on short finals, in preference to ATC surface W/V reports, is generally NOT A GOOD IDEA; it's their accuracy and relevance that seem to me to be the problem, not their currency.

I have more confidence in 757/767 IRS generated wind data than field reported winds(if there's a disagreement). If a runway approach end windsock indicates a different wind than is reported I can't remember the IRS generated wind being in disagreement with the windsock. It's fairly simple to glance at the wind display arrow just prior to flare/touchdown.
Reported winds are the legal answer, but all available data should be used.
A300 wind display on Nav display was worthless. Wind velocity/direction on FMC page was much better.
