Hi,

During CDU preflight my company procedure is to insert TOC wind in Perf Init page then update the temperature and wind manually in Perf Init page as we go into cruise. What's the significance of this? After going into cruise why do we need to update the wind/temp in perf init page when we are loading all the winds from ACARS in legs page?

Thanks in advance.
