Narrative:
Per our pre departure clearance, the ATC cleared route included a SID but a few lines below our cleared route, in a different paragraph, we were instructed to disregard the 'dp/SID' and fly runway heading. None of the crew members caught this and without being assigned a heading with our takeoff clearance, the flight crew executed the SID. After contacting departure control, we were told of our mistake and given a heading and continued our climb to 7000 ft MSL. After leveling at 7000 ft MSL, departure said 'expedite climb to 8000 ft.' shortly after leveling at 8000 ft, departure told us to climb to 15000 ft and said he previously told us 3 times to climb to 15000 ft -- a clearance which we never heard. After initiating a climb, we received an RA telling us to 'monitor vertical speed and climb at 300 FPM.' the pre departure clearance was a contributing factor as our route contained a SID and in another part of the pre departure clearance the clearance was to disregard the SID. Also, not being assigned a heading with our takeoff clearance was a factor. After realizing our mistake of flying the SID we did our absolute best as a crew to comply with ATC instructions. Also, I feel that the use of excellent CRM by our crew helped this event have a positive outcome.
Original NASA ASRS Text
Title: DC10 CREW FLEW DEP SID VERSUS RWY HDG ON DEP AT LAS. THEY HAD AN NMAC WITH ANOTHER ACFT.
Narrative: PER OUR PDC, THE ATC CLRED RTE INCLUDED A SID BUT A FEW LINES BELOW OUR CLRED RTE, IN A DIFFERENT PARAGRAPH, WE WERE INSTRUCTED TO DISREGARD THE 'DP/SID' AND FLY RWY HDG. NONE OF THE CREW MEMBERS CAUGHT THIS AND WITHOUT BEING ASSIGNED A HDG WITH OUR TKOF CLRNC, THE FLC EXECUTED THE SID. AFTER CONTACTING DEP CTL, WE WERE TOLD OF OUR MISTAKE AND GIVEN A HDG AND CONTINUED OUR CLB TO 7000 FT MSL. AFTER LEVELING AT 7000 FT MSL, DEP SAID 'EXPEDITE CLB TO 8000 FT.' SHORTLY AFTER LEVELING AT 8000 FT, DEP TOLD US TO CLB TO 15000 FT AND SAID HE PREVIOUSLY TOLD US 3 TIMES TO CLB TO 15000 FT -- A CLRNC WHICH WE NEVER HEARD. AFTER INITIATING A CLB, WE RECEIVED AN RA TELLING US TO 'MONITOR VERT SPD AND CLB AT 300 FPM.' THE PDC WAS A CONTRIBUTING FACTOR AS OUR RTE CONTAINED A SID AND IN ANOTHER PART OF THE PDC THE CLRNC WAS TO DISREGARD THE SID. ALSO, NOT BEING ASSIGNED A HDG WITH OUR TKOF CLRNC WAS A FACTOR. AFTER REALIZING OUR MISTAKE OF FLYING THE SID WE DID OUR ABSOLUTE BEST AS A CREW TO COMPLY WITH ATC INSTRUCTIONS. ALSO, I FEEL THAT THE USE OF EXCELLENT CRM BY OUR CREW HELPED THIS EVENT HAVE A POSITIVE OUTCOME.
