Narrative:

We had expected and briefed runway 34 departure. Instead we were cleared to taxi to runway 28. During taxi; rechked takeoff data and briefed the departure; and noise abatement. I have just been notified that I might have violated the noise abatement procedure for runway 28. In the future I will take more time to ensure that every procedure is strictly adhered to. However; in reviewing this event in the comfort of my home; I can't help believe that other pilots have done what I have done; and will continue to do so. 1) it states; 'climb runway heading for vectors. No left turns below 4300 ft.' 2) on the next page under noise abatement; it states 'climb on the localizer 283 to 6500 ft before proceeding on course.' 3) above that; in the preceding paragraph; it states: SID cancellation does not terminate noise abatement procedure. First of all; it is clear and easy now to remember 4300 ft; 6500 ft don't turn even if told to do so; etc; but with so many tasks to do just before takeoff; I believe that the way this is presented will continue to create confusion for pilots who rarely go to calgary. (Why not issue the stampede departure instead.) second; I cannot be positive; but I seem to remember that departure control told us to turn left at some point during the climb before the end of the noise abatement altitude. If I am correct; I really don't think this is a good idea. We are programmed to respond and follow instructions. In most other places noise abatement or not; they tell you to do something; you do it; and it should remain like that. Imagine the chaos if we had to rechk notes; cautions; NOTAMS; or authenticate every instruction.

Title: MD83 FLT CREW HAS NOISE ABATEMENT VIOLATION DEP CYYC.

Narrative: WE HAD EXPECTED AND BRIEFED RWY 34 DEP. INSTEAD WE WERE CLRED TO TAXI TO RWY 28. DURING TAXI; RECHKED TKOF DATA AND BRIEFED THE DEP; AND NOISE ABATEMENT. I HAVE JUST BEEN NOTIFIED THAT I MIGHT HAVE VIOLATED THE NOISE ABATEMENT PROC FOR RWY 28. IN THE FUTURE I WILL TAKE MORE TIME TO ENSURE THAT EVERY PROC IS STRICTLY ADHERED TO. HOWEVER; IN REVIEWING THIS EVENT IN THE COMFORT OF MY HOME; I CAN'T HELP BELIEVE THAT OTHER PLTS HAVE DONE WHAT I HAVE DONE; AND WILL CONTINUE TO DO SO. 1) IT STATES; 'CLB RWY HDG FOR VECTORS. NO L TURNS BELOW 4300 FT.' 2) ON THE NEXT PAGE UNDER NOISE ABATEMENT; IT STATES 'CLB ON THE LOC 283 TO 6500 FT BEFORE PROCEEDING ON COURSE.' 3) ABOVE THAT; IN THE PRECEDING PARAGRAPH; IT STATES: SID CANCELLATION DOES NOT TERMINATE NOISE ABATEMENT PROC. FIRST OF ALL; IT IS CLR AND EASY NOW TO REMEMBER 4300 FT; 6500 FT DON'T TURN EVEN IF TOLD TO DO SO; ETC; BUT WITH SO MANY TASKS TO DO JUST BEFORE TKOF; I BELIEVE THAT THE WAY THIS IS PRESENTED WILL CONTINUE TO CREATE CONFUSION FOR PLTS WHO RARELY GO TO CALGARY. (WHY NOT ISSUE THE STAMPEDE DEP INSTEAD.) SECOND; I CANNOT BE POSITIVE; BUT I SEEM TO REMEMBER THAT DEP CTL TOLD US TO TURN L AT SOME POINT DURING THE CLB BEFORE THE END OF THE NOISE ABATEMENT ALT. IF I AM CORRECT; I REALLY DON'T THINK THIS IS A GOOD IDEA. WE ARE PROGRAMMED TO RESPOND AND FOLLOW INSTRUCTIONS. IN MOST OTHER PLACES NOISE ABATEMENT OR NOT; THEY TELL YOU TO DO SOMETHING; YOU DO IT; AND IT SHOULD REMAIN LIKE THAT. IMAGINE THE CHAOS IF WE HAD TO RECHK NOTES; CAUTIONS; NOTAMS; OR AUTHENTICATE EVERY INSTRUCTION.
