Human Factors
The flight plan consisted of many direct fixes including the 'new' fixes such as KD54S. I had just read a report the previous day about mis-entry into the FMC using similar fixes. I was conscious of the potential for error while programming the FMC but still managed to transpose the cleared fix - KD54S- into an incorrect fix KD45S. The first officer and I noticed the big dog-leg in the flight plan; but I had thought it was for avoidance of a very large dissipating weather cell around the Denver area. Approximately 5 minutes after passing CLEVE; Denver Center queried us regarding the fix we were navigating to. I responded to KD45S and immediately saw the correct fix should have been KD54S. I entered the fix into the FMC and told the Controller what had happened and that we were turning toward KD54S. The Controller said it was not a problem and issued a clearance further west and more direct toward our destination.
