Prior to takeoff on a simulated instrument training flight (VFR) ATC issued 'position and hold' instructions. The private pilot instrument student read back the instructions and taxied onto the active runway. The student then applied takeoff power and proceeded with the takeoff without further clearance. The tower controller calmly advised the student that he should wait for takeoff clearance next time. The student acknowledged and the flight continued uneventfully. Both the student and the instructor (myself) allowed the takeoff to proceed without realizing clearance had not been received. Ironically, a conversation concerning clrncs was taking place when the 'position and hold' instructions were received and we were both distraction to the point that neither of us thought about not having received takeoff clearance. Additionally, the instructor could have been fatigued from the previous day's activities which involved a trip from dallas to oklahoma city to visit the FAA-cami facility for high altitude physiology training. The instructor is very experienced and flies out of this particular airport daily. The instrument student received his private pilot training at this same airport and is familiar with ATC procedures. It has become glaringly apparent that a little distraction combined with fatigue can easily overcome experience and familiarity if caution and good judgement are not used.

Title: GA TRAINEE TKOF WITHOUT ATC CLRNC AT ADS, TX, WITH INSTRUCTOR ON BOARD IN A PA28-140.
Narrative: PRIOR TO TKOF ON A SIMULATED INST TRAINING FLT (VFR) ATC ISSUED 'POS AND HOLD' INSTRUCTIONS. THE PVT PLT INST STUDENT READ BACK THE INSTRUCTIONS AND TAXIED ONTO THE ACTIVE RWY. THE STUDENT THEN APPLIED TKOF PWR AND PROCEEDED WITH THE TKOF WITHOUT FURTHER CLRNC. THE TWR CTLR CALMLY ADVISED THE STUDENT THAT HE SHOULD WAIT FOR TKOF CLRNC NEXT TIME. THE STUDENT ACKNOWLEDGED AND THE FLT CONTINUED UNEVENTFULLY. BOTH THE STUDENT AND THE INSTRUCTOR (MYSELF) ALLOWED THE TKOF TO PROCEED WITHOUT REALIZING CLRNC HAD NOT BEEN RECEIVED. IRONICALLY, A CONVERSATION CONCERNING CLRNCS WAS TAKING PLACE WHEN THE 'POS AND HOLD' INSTRUCTIONS WERE RECEIVED AND WE WERE BOTH DISTR TO THE POINT THAT NEITHER OF US THOUGHT ABOUT NOT HAVING RECEIVED TKOF CLRNC. ADDITIONALLY, THE INSTRUCTOR COULD HAVE BEEN FATIGUED FROM THE PREVIOUS DAY'S ACTIVITIES WHICH INVOLVED A TRIP FROM DALLAS TO OKLAHOMA CITY TO VISIT THE FAA-CAMI FACILITY FOR HIGH ALT PHYSIOLOGY TRAINING. THE INSTRUCTOR IS VERY EXPERIENCED AND FLIES OUT OF THIS PARTICULAR ARPT DAILY. THE INST STUDENT RECEIVED HIS PVT PLT TRAINING AT THIS SAME ARPT AND IS FAMILIAR WITH ATC PROCS. IT HAS BECOME GLARINGLY APPARENT THAT A LITTLE DISTR COMBINED WITH FATIGUE CAN EASILY OVERCOME EXPERIENCE AND FAMILIARITY IF CAUTION AND GOOD JUDGEMENT ARE NOT USED.
