Narrative:

This event occurred on departure from sdl on the SCOT5 SID. We had loaded the SCOT5 into the FMS as we normally do. We have flown this SID before using the same FMS and had never experienced any problems. This time; however; the FMS did not follow the procedure which consists of a 300 degree heading after departure to intercept the pxr 336 degree radial to the banyo intersection. We immediately turned right to a heading to intercept the radial but went through it. The controller did not say anything about it. He then gave us a heading to fly to the northeast which was part of our flight plan. The gist of all of this is that we were not prepared for the automation to do something unexpected. Day after day the automation does exactly what you expect it to do; so when it does not; it tends to take you by surprise (complacency!).

Narrative: This event occurred on departure from SDL on the SCOT5 SID. We had loaded the SCOT5 into the FMS as we normally do. We have flown this SID before using the same FMS and had never experienced any problems. This time; however; the FMS did not follow the procedure which consists of a 300 degree heading after departure to intercept the PXR 336 degree radial to the BANYO Intersection. We immediately turned right to a heading to intercept the radial but went through it. The Controller did not say anything about it.
