in the 320 qrh there is a cost index value given for quick determination of the lrc cost index. however, most captains prefer opening the fcom for determining the lrc speed, in case of lower level cruise. also the speeds given by that particular cost index are no where near the fcom lrc speeds...if so, then why is that cost index mentioned in the fcom.
