Narrative:

On mar/xx/95, heavy mountain wave activity in colorado required routing aircraft around this area from a dispatch perspective. Flts abc/xa, def/xa/ ghi/xb (pdx-dfw) were among the affected flts. I elected to route them over fmn for safety. This required using a little used routing. All rtes in our database are prestored involving appropriate flight levels. In this case however the database held improper en route flight levels, a wrong way airway indicator actually. When filing these flight plans I missed this error. The crew on ghi/xb brought this mistake to my attention. The database was immediately corrected. I do not believe any flts accepted improper flight levels. My personal attention to this area has been greatly increased. Reminding me that occasionally computers are programmed improperly.

IN THIS CASE HOWEVER THE DATABASE HELD IMPROPER ENRTE FLT LEVELS, A WRONG WAY AIRWAY INDICATOR ACTUALLY. WHEN FILING THESE FLT PLANS I MISSED THIS ERROR. THE CREW ON GHI/XB BROUGHT THIS MISTAKE TO MY ATTN. THE DATABASE WAS IMMEDIATELY CORRECTED. I DO NOT BELIEVE ANY FLTS ACCEPTED IMPROPER FLT LEVELS.
