Narrative:

Told to taxi into position on runway 34 at pwk while holding short on taxiway a. In doing so I stopped the aircraft on the pad at the beginning of runway 34. I thought the aircraft was centered along the extended centerline. During the takeoff roll I realized the approaching lights were not centerline lights but runway edge lights. Sudden corrective action was necessary to keep the aircraft on the runway. I feel that the lack of taxiway lights (reflector only) and the odd shape of the pad (or overrun area) helped to mislead me to improper line-up of the aircraft. Duty time remained within limits at all times, however, fatigue was probably also a contributing factor as this day and the previous were very long days. In the future, this pad or overrun area should not be used for line-up to depart, and the crew should review and discuss airport services such as lighting system available for the runway in use. Callback conversation with reporter revealed the following information: reporter states that the area is not lighted at all, just taxiway reflectors to guide one. He believes that there are no lines painted to assist the pilot to the centerline. There are chevrons in that area, but they are the small ones which do allow for takeoff from the runway extension. It appears that this may have been a ramp area for the hangars in the area prior to the long runway being built. Some proper lighting would be the solution to lining up off center. The aircraft was a westwind. Reporter has talked with the chief pilot of his company.

Title: WESTWIND CORP PLT LINES UP WITH EDGE LIGHTS OF RWY INSTEAD OF CTRLINE DUE TO OFFSET OF RAMP AREA AT DEP END OF THE RWY AND NO TXWY LIGHTING OR MARKINGS.

Narrative: TOLD TO TAXI INTO POS ON RWY 34 AT PWK WHILE HOLDING SHORT ON TXWY A. IN DOING SO I STOPPED THE ACFT ON THE PAD AT THE BEGINNING OF RWY 34. I THOUGHT THE ACFT WAS CTRED ALONG THE EXTENDED CTRLINE. DURING THE TKOF ROLL I REALIZED THE APCHING LIGHTS WERE NOT CTRLINE LIGHTS BUT RWY EDGE LIGHTS. SUDDEN CORRECTIVE ACTION WAS NECESSARY TO KEEP THE ACFT ON THE RWY. I FEEL THAT THE LACK OF TXWY LIGHTS (REFLECTOR ONLY) AND THE ODD SHAPE OF THE PAD (OR OVERRUN AREA) HELPED TO MISLEAD ME TO IMPROPER LINE-UP OF THE ACFT. DUTY TIME REMAINED WITHIN LIMITS AT ALL TIMES, HOWEVER, FATIGUE WAS PROBABLY ALSO A CONTRIBUTING FACTOR AS THIS DAY AND THE PREVIOUS WERE VERY LONG DAYS. IN THE FUTURE, THIS PAD OR OVERRUN AREA SHOULD NOT BE USED FOR LINE-UP TO DEPART, AND THE CREW SHOULD REVIEW AND DISCUSS ARPT SVCS SUCH AS LIGHTING SYS AVAILABLE FOR THE RWY IN USE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES THAT THE AREA IS NOT LIGHTED AT ALL, JUST TXWY REFLECTORS TO GUIDE ONE. HE BELIEVES THAT THERE ARE NO LINES PAINTED TO ASSIST THE PLT TO THE CTRLINE. THERE ARE CHEVRONS IN THAT AREA, BUT THEY ARE THE SMALL ONES WHICH DO ALLOW FOR TKOF FROM THE RWY EXTENSION. IT APPEARS THAT THIS MAY HAVE BEEN A RAMP AREA FOR THE HANGARS IN THE AREA PRIOR TO THE LONG RWY BEING BUILT. SOME PROPER LIGHTING WOULD BE THE SOLUTION TO LINING UP OFF CTR. THE ACFT WAS A WESTWIND. RPTR HAS TALKED WITH THE CHIEF PLT OF HIS COMPANY.
