Narrative:

We were assigned the dallas 6 departure out of dallas love field. This departure calls for a right turn to a heading of 360 degrees at 5.5 DME off of the localizer. Our FMS did not catch this and we simply missed the turn. Departure caught us at about 8 mi and told us to immediately turn to 090 degrees. We complied. Callback conversation with reporter revealed the following information: reporter stated that the FMC autoplt mode selector was apparently never activated prior to the SID turning point. Therefore, since the aircraft actions were not mentioned by either crew member to assure that the turn was made, they were still flying on runway heading waiting for the aircraft to do whatever it needed to when departure controller alerted them to their error and gave them an immediate turn. Reporter further stated that the flight was really a part 91 corporate flight.
