NFR,
Landed on 11 at o'dark thirty the other morning with very little wind reported on the ATIS. All the way to touchdown the magic box was indicating 20+ kts of HWC, the windsock was limp, yet no shear whatsoever during approach .
So unless more modern equipment has better magic boxes than the smurfjet, I'm somewhat sceptical of spot winds given from an aircraft that is manouvering for landing.
