Narrative:

Flight plan was ksea.sea J90 hln. Pre departure clearance said 'cleared as filed' sea J90 hln dpr...cvg. Only in the remarks section of the pre departure clearance was a reference to the mountain 2 departure. We didn't see the remark. We took off after a light twin and turned on course as we thought we were cleared. We had the other airplane in sight as we climbed through his altitude. After turning, departure control asked whether we had been assigned a SID, we didn't think so at the time and said 'no.' pre departure clearance format is not standardized. It also does not conform to the way clrncs are read to you from clearance delivery. In our case, we were not 'cleared as filed' because the routing was modified by a SID. This should be corrected immediately to prevent this type of conflict. Putting 'cleared as filed' up on top followed by a SID in the remarks section is too easy to miss in the last min flurry of activity at pushback time. I've enclosed examples of 2 flight plans and their respective pre departure clearance's. Supplemental information from acn 246488: I believe the pre departure clearance should be standardized and vital information should be in the outlined section of pre departure clearance. This should include departures and anything that is not 'cleared as filed.'

Original NASA ASRS Text

Title: FLC OVERLOOKED SID ADDED TO THEIR FLT PLAN RTE ON THEIR PDC. THEY FLEW WRONG HDG AFTER TKOF CAUSING A CONFLICT.

Narrative: FLT PLAN WAS KSEA.SEA J90 HLN. PDC SAID 'CLRED AS FILED' SEA J90 HLN DPR...CVG. ONLY IN THE REMARKS SECTION OF THE PDC WAS A REF TO THE MOUNTAIN 2 DEP. WE DIDN'T SEE THE REMARK. WE TOOK OFF AFTER A LIGHT TWIN AND TURNED ON COURSE AS WE THOUGHT WE WERE CLRED. WE HAD THE OTHER AIRPLANE IN SIGHT AS WE CLBED THROUGH HIS ALT. AFTER TURNING, DEP CTL ASKED WHETHER WE HAD BEEN ASSIGNED A SID, WE DIDN'T THINK SO AT THE TIME AND SAID 'NO.' PDC FORMAT IS NOT STANDARDIZED. IT ALSO DOES NOT CONFORM TO THE WAY CLRNCS ARE READ TO YOU FROM CLRNC DELIVERY. IN OUR CASE, WE WERE NOT 'CLRED AS FILED' BECAUSE THE ROUTING WAS MODIFIED BY A SID. THIS SHOULD BE CORRECTED IMMEDIATELY TO PREVENT THIS TYPE OF CONFLICT. PUTTING 'CLRED AS FILED' UP ON TOP FOLLOWED BY A SID IN THE REMARKS SECTION IS TOO EASY TO MISS IN THE LAST MIN FLURRY OF ACTIVITY AT PUSHBACK TIME. I'VE ENCLOSED EXAMPLES OF 2 FLT PLANS AND THEIR RESPECTIVE PDC'S. SUPPLEMENTAL INFO FROM ACN 246488: I BELIEVE THE PDC SHOULD BE STANDARDIZED AND VITAL INFO SHOULD BE IN THE OUTLINED SECTION OF PDC. THIS SHOULD INCLUDE DEPS AND ANYTHING THAT IS NOT 'CLRED AS FILED.'
