Narrative:

Takeoff was made from displaced threshold instead of beginning of paved runway. I feel some contributing factors were: not studying airport runway chart closely enough to realize. We had an ATC delay and were at the end of our takeoff release time and while taxiing out saw runway end markings and at that time was cleared for takeoff so I took the runway for takeoff. Fortunately aircraft weight was extremely light and runway was a relatively long one.

Original NASA ASRS Text

Title: TOOK OFF FROM DISPLACED THRESHOLD, FULL RWY LENGTH NOT UTILIZED.

Narrative: TKOF WAS MADE FROM DISPLACED THRESHOLD INSTEAD OF BEGINNING OF PAVED RWY. I FEEL SOME CONTRIBUTING FACTORS WERE: NOT STUDYING ARPT RWY CHART CLOSELY ENOUGH TO REALIZE. WE HAD AN ATC DELAY AND WERE AT THE END OF OUR TKOF RELEASE TIME AND WHILE TAXIING OUT SAW RWY END MARKINGS AND AT THAT TIME WAS CLRED FOR TKOF SO I TOOK THE RWY FOR TKOF. FORTUNATELY ACFT WT WAS EXTREMELY LIGHT AND RWY WAS A RELATIVELY LONG ONE.
