CORP PLT HAS HDG DEV WHEN MIXING NARRATIVE AND GRAPHIC PARTS OF DEP.

Narrative

I WAS GIVEN THE OASIS 7 DEP; BEATY TRANSITION; FROM LAS VEGAS; NV; MCCARRAN FIELD; DEPARTING RWY 19L. WHEN I REVIEWED THE DEP PROC AFTER RECEIVING MY CLRNC; I READ THE NARRATIVE OF THE WRONG SID AND LOOKED AT THE GRAPHIC OF THE APPROPRIATE DEP. WHEN I DEPARTED I FLEW THE PROC FOR THE SID THAT I HAD READ AND NOT THE SID I WAS CLRED FOR. THE ERROR WAS IDENTED WHEN AFTER COMPLETING A TURN TO THE N; INCORRECTLY; THE DEP CTLR REQUESTED MY HDG. HE THEN INSTRUCTED ME TO MAKE AN IMMEDIATE TURN TO A 250 DEG HDG AND COMPLY WITH THE SID. AFTER HIS INSTRUCTION TO CHANGE HDGS HE COMMENTED ON THE ROUTING THAT I SHOULD HAVE BEEN USING. I ASSUMED THE NEW HDG; COMPLIED WITH THE REMAINDER OF THE SID; AND CONTINUED WITHOUT FURTHER INCIDENT. THE MISTAKE I MADE WAS PRIMARILY HUMAN BUT AGGRAVATED BY POORLY DISPLAYED PROCS. THE NOS CHARTS FOR DEP PROCS THAT REQUIRE 2 PAGES; DISPLAY THE GRAPHIC ON ONE PAGE AND THE NARRATIVE ON A SUCCEEDING PAGE. WHEN I OPENED THE CHART BOOK TO THE OASIS 7 DEP; THE NARRATIVE OF THE PRECEDING PROC SEEMED TO LEAD TO THE OASIS 7 GRAPHIC. I THINK THE CONTINUATION OF A PROC SHOULD BE DISPLAYED IN A MORE RECOGNIZABLE MANNER.
