WRONG.  The error occurs in varying amounts depending on the wh= ere the probe is mounted on the skin.  On the leading edge, the error is t= he Ram air , but the mix between the two depends on the local velocity where t= he probe is mounted. 

In other words, the OAT sensor error is inescapable.  But you can correct as Bruce notes, using either a pencil or calculator, or your black = box, if it was set up to do so.
