Narrative:

It was an IFR flight in VMC from rdu with a departure time of approximately XA00 local time. I acquired the ATIS and proceeded with my IFR clearance. After receiving clearance; I switched over to ground to receive my taxi clearance. I was instructed by the ground controller to taxi for an intersection departure without any prompting from me. I taxied as instructed for the departure and upon reaching the runway was instructed to 'fly runway heading; cleared for takeoff at intersection C.' I forgot which runway was in use so I referenced the winds I had received from the ATIS instead of the runway which I should have used. Since the runway was 5L/23R and the winds were from 290 degrees at 9 KTS; I assumed runway 23R was in use but did not clarify. I departed the wrong runway and was notified of my mistake after becoming airborne. No other airplanes were in the area. Contributing factors include stress derived from being rushed for takeoff; lack of airport information; and miscom. Being rushed for takeoff caused me to write down an incomplete ATIS; which resulted in the lack of information; more specifically the runway in use. My corrective actions include writing down the entire ATIS to confirm the active runway while maintaining vigilance with taxi and takeoff clearance.

Title: A PA32 PILOT DEPARTED A WRONG RWY AFTER BEING RUSHED FOR TKOF; NOT COPYING ATIS COMPLETELY; AND FAILING TO ASK FOR THE RWY.

Narrative: IT WAS AN IFR FLT IN VMC FROM RDU WITH A DEP TIME OF APPROX XA00 LCL TIME. I ACQUIRED THE ATIS AND PROCEEDED WITH MY IFR CLRNC. AFTER RECEIVING CLRNC; I SWITCHED OVER TO GND TO RECEIVE MY TAXI CLRNC. I WAS INSTRUCTED BY THE GND CTLR TO TAXI FOR AN INTXN DEP WITHOUT ANY PROMPTING FROM ME. I TAXIED AS INSTRUCTED FOR THE DEP AND UPON REACHING THE RWY WAS INSTRUCTED TO 'FLY RWY HDG; CLRED FOR TKOF AT INTXN C.' I FORGOT WHICH RWY WAS IN USE SO I REFED THE WINDS I HAD RECEIVED FROM THE ATIS INSTEAD OF THE RWY WHICH I SHOULD HAVE USED. SINCE THE RWY WAS 5L/23R AND THE WINDS WERE FROM 290 DEGS AT 9 KTS; I ASSUMED RWY 23R WAS IN USE BUT DID NOT CLARIFY. I DEPARTED THE WRONG RWY AND WAS NOTIFIED OF MY MISTAKE AFTER BECOMING AIRBORNE. NO OTHER AIRPLANES WERE IN THE AREA. CONTRIBUTING FACTORS INCLUDE STRESS DERIVED FROM BEING RUSHED FOR TKOF; LACK OF ARPT INFO; AND MISCOM. BEING RUSHED FOR TKOF CAUSED ME TO WRITE DOWN AN INCOMPLETE ATIS; WHICH RESULTED IN THE LACK OF INFO; MORE SPECIFICALLY THE RWY IN USE. MY CORRECTIVE ACTIONS INCLUDE WRITING DOWN THE ENTIRE ATIS TO CONFIRM THE ACTIVE RWY WHILE MAINTAINING VIGILANCE WITH TAXI AND TKOF CLRNC.
