Hi, I was trying to do a flight from KORD to KJFK today but I got stuck at the departure phase. According to information that I found, KORD only has 1 departure chart.

How are we meant to figure out what our SID will be from that? My problems were magnified by the fact that my AIRAC data didn't have most of those way points so I was totally lost in a word. In cases such as this, is clearance meant to simply specify... "fly runway heading then turn to blah degrees upon reaching a certain altitude and fly direct to for example DUFEE and then proceed with own navigation"?
