Narrative:

We were given chezz departure with dry heat transition government departure plate does not give a narrative from chezz intersection to dry heat. Consequently, the GPS was programmed for dry heat after chezz. The aircraft turned to 55 degree heading to dry heat. Should have been 110 degree heading to close intersection and intermediate fixes between close and dry heat. First officer was new to aircraft. Government chart was too vague in description. Also, departure lists multiple fixes, depending which runway you are departing, which lead the crew into deleting fixes at critical times after runway assignment. SID is too complicated for use with older FMS and GPS equipment.

Title: A CORPORATE TURBOJET FO RPTED MAKING A TRACK DEV DURING THE CHEZZ SID IN PHX.

Narrative: WE WERE GIVEN CHEZZ DEP WITH DRY HEAT TRANSITION GOV DEP PLATE DOES NOT GIVE A NARRATIVE FROM CHEZZ INTXN TO DRY HEAT. CONSEQUENTLY, THE GPS WAS PROGRAMMED FOR DRY HEAT AFTER CHEZZ. THE ACFT TURNED TO 55 DEG HDG TO DRY HEAT. SHOULD HAVE BEEN 110 DEG HDG TO CLOSE INTXN AND INTERMEDIATE FIXES BTWN CLOSE AND DRY HEAT. FO WAS NEW TO ACFT. GOV CHART WAS TOO VAGUE IN DESCRIPTION. ALSO, DEP LISTS MULTIPLE FIXES, DEPENDING WHICH RWY YOU ARE DEPARTING, WHICH LEAD THE CREW INTO DELETING FIXES AT CRITICAL TIMES AFTER RWY ASSIGNMENT.
