Looking at the OZZIE FOUR departure off APC (first page shown) the instructions are, e.g.,
TAKEOFF RUNWAY 19L: Climb on heading 186° to intercept course 269° to KLARK, then on track 342° to FIRTO at or above 2700, then on track 350° to OZIEE at or above 6000, thence...
I know the first step can be done with GPS equipment by using the OBS setting with KLARK as the reference, but is this what the design intends? I've never seen the OBS mode used for anything except runway centerlines and the like. Using it for IFR nav relative to a GPS waypoint never came up in training. I would have expected the procedure to include a flyby waypoint where the 89° radial off KLARK meets the 186° radial off APC, which would make the first turn work like any other. How do people program & fly something like this in practice? (Also - more of a TERPS question - why are the courses to KLARK off 19R/L not the same & likewise for 1R/L first turns?)
ETA: this is not in reference to any specific equipment beyond RNAV capability. I'm just puzzled by the specificity of the courses to the first waypoint, and the SID charting showing turns at specific points in space not associated with a waypoint. It says specifically "intercept course 269 to KLARK". I can use OBS mode to do this, but is that what's intended?
