Narrative:

We were cleared via the garland three departure from runway 31R. After takeoff we flew runway heading until we reached at least 3;000 ft before turning directly to the TTT VOR. Where we then expected to be turned out bound to the north then direct clare intersection. We never reached the VOR because we requested vectors to clare immediately and were turned to the north as requested. We resumed the departure and when we arrived at our destination; we were then told to contact dal tower. Until we talked to the tower we had no idea that we had been issued a pilot deviation. My first officer and I then sat down for a three hour ground lesson to better understand what we had done wrong. The issue was that we failed to read a 'for jets only' note on the naco departure plate. It was very confusing for us. The note stated that 'after departure we were to fly heading 310 to 5.5 DME then expect vectors out bound'. What we planned to do was fly to the TTT VOR and track a radial out bound which would have been the appropriate procedure for prop planes. We then met with a supervisor at the tower so we could sit down and go over the visual and voice recordings of the incident to educate us on why what had happened was so crucial and how we can prevent doing so in the future. He then led us on a personal tour of the tower so we could better understand their operations. If you compare the commercially provided clare SID charts to the naco charts; you will see that they are much easier to read in terms of the jets narrative which is clearly stated on the same page as the departure graphic. On the naco charts; the narrative is on a separate and overly wordy page separate from the graphic. In conclusion; my first officer and I confessed to our mistake; and took extreme action in correcting it.

Title: The flight crew of a CE-560 suffered a track deviation when they misinterpreted the takeoff portions of the CLARE SID departing Runway 31R at DAL.

Narrative: We were cleared via the Garland Three Departure from Runway 31R. After takeoff we flew runway heading until we reached at least 3;000 FT before turning directly to the TTT VOR.
