Narrative:

I was flying with a new first officer (1 1/2 months). I had been demonstrating the proper advancement of the thrust levers; as he needed to advance them a little faster. We evidently received a 'position and hold' clearance. I thought we had been cleared for takeoff. Advanced the thrust levers and began our takeoff roll. My first officer did not say anything. About halfway into our takeoff roll; the tower said 'cleared for takeoff.' it was then that I realized we must not have had a takeoff clearance. Contributing factors: this was day 4 of a 4 day trip. I had a XA00 am wakeup; by far; the earliest of the 4 day trip. I was tired and ready for the trip to be over. This was the last round trip (legs 4 and 5). We had been swapped into this round trip; as our last round trip had canceled. This flight was already late when we arrived on the gate from our previous trip. Considering our early report; 5 leg day; trip reassignment; we may have been approaching fatigue.

Title: CRJ200 FLT CREW DEPARTS WITHOUT TKOF CLEARANCE DURING CAPT DEMONSTRATION OF PROPER THRUST SETTING TECHNIQUE.

Narrative: I WAS FLYING WITH A NEW FO (1 1/2 MONTHS). I HAD BEEN DEMONSTRATING THE PROPER ADVANCEMENT OF THE THRUST LEVERS; AS HE NEEDED TO ADVANCE THEM A LITTLE FASTER. WE EVIDENTLY RECEIVED A 'POS AND HOLD' CLRNC. I THOUGHT WE HAD BEEN CLRED FOR TKOF. ADVANCED THE THRUST LEVERS AND BEGAN OUR TKOF ROLL. MY FO DID NOT SAY ANYTHING. ABOUT HALFWAY INTO OUR TKOF ROLL; THE TWR SAID 'CLRED FOR TKOF.' IT WAS THEN THAT I REALIZED WE MUST NOT HAVE HAD A TKOF CLRNC. CONTRIBUTING FACTORS: THIS WAS DAY 4 OF A 4 DAY TRIP. I HAD A XA00 AM WAKEUP; BY FAR; THE EARLIEST OF THE 4 DAY TRIP. I WAS TIRED AND READY FOR THE TRIP TO BE OVER. THIS WAS THE LAST ROUND TRIP (LEGS 4 AND 5). WE HAD BEEN SWAPPED INTO THIS ROUND TRIP; AS OUR LAST ROUND TRIP HAD CANCELED. THIS FLT WAS ALREADY LATE WHEN WE ARRIVED ON THE GATE FROM OUR PREVIOUS TRIP. CONSIDERING OUR EARLY RPT; 5 LEG DAY; TRIP REASSIGNMENT; WE MAY HAVE BEEN APCHING FATIGUE.
