Narrative:

On jul/xx/95 at about XY00 am at hgr airport, I taxied past the hold lines for an intersection departure from taxiway C to runway 27. Then I departed runway 9. I also didn't change from ground frequency to tower. Here is what happened. It was around 97 degrees at approximately XX30 in the morning and high humidity. I started my engine and did my runup. The oil temperature was steady climbing. I started rushing things. I got my clearance to taxiway C to the intersection of runway 27 and runway 9 for an intersection departure. I was the only airplane around. So as I taxied past the hold lines I asked for clearance on ground frequency and was yelled at by the controller to get on the tower frequency and get back to the hold lines. I did a 180 degree turn and taxied back 25 ft to the hold lines and called the tower. He cleared me for immediate departure on runway 27 and I turned left down runway 9. About 1/3 of the way down the runway I realized that I was departing runway 9. At this point I was committed so I had to keep going. I took off and subsequently I was yelled at by the controller again. In retrospect, I think the combination of the heat, my hurried runup, and the controller getting very verbal raised my anxiety level to a point of confusion. I also think when the same controller is working ground and tower and transmitting on both frequencys this makes it easier to forget to switch frequencys. Next time I get confused I will stop for as long as it takes to calm down and understand where I am and where I am going.

Title: PVT PLT OF AN SMA SEL FAILED TO STOP TAXIING AT THE RWY HOLD SHORT LINE AND IN ADDITION TOOK OFF ON THE WRONG RWY.

Narrative: ON JUL/XX/95 AT ABOUT XY00 AM AT HGR ARPT, I TAXIED PAST THE HOLD LINES FOR AN INTXN DEP FROM TXWY C TO RWY 27. THEN I DEPARTED RWY 9. I ALSO DIDN'T CHANGE FROM GND FREQ TO TWR. HERE IS WHAT HAPPENED. IT WAS AROUND 97 DEGS AT APPROX XX30 IN THE MORNING AND HIGH HUMIDITY. I STARTED MY ENG AND DID MY RUNUP. THE OIL TEMP WAS STEADY CLBING. I STARTED RUSHING THINGS. I GOT MY CLRNC TO TXWY C TO THE INTXN OF RWY 27 AND RWY 9 FOR AN INTXN DEP. I WAS THE ONLY AIRPLANE AROUND. SO AS I TAXIED PAST THE HOLD LINES I ASKED FOR CLRNC ON GND FREQ AND WAS YELLED AT BY THE CTLR TO GET ON THE TWR FREQ AND GET BACK TO THE HOLD LINES. I DID A 180 DEG TURN AND TAXIED BACK 25 FT TO THE HOLD LINES AND CALLED THE TWR. HE CLRED ME FOR IMMEDIATE DEP ON RWY 27 AND I TURNED L DOWN RWY 9. ABOUT 1/3 OF THE WAY DOWN THE RWY I REALIZED THAT I WAS DEPARTING RWY 9. AT THIS POINT I WAS COMMITTED SO I HAD TO KEEP GOING. I TOOK OFF AND SUBSEQUENTLY I WAS YELLED AT BY THE CTLR AGAIN. IN RETROSPECT, I THINK THE COMBINATION OF THE HEAT, MY HURRIED RUNUP, AND THE CTLR GETTING VERY VERBAL RAISED MY ANXIETY LEVEL TO A POINT OF CONFUSION. I ALSO THINK WHEN THE SAME CTLR IS WORKING GND AND TWR AND XMITTING ON BOTH FREQS THIS MAKES IT EASIER TO FORGET TO SWITCH FREQS. NEXT TIME I GET CONFUSED I WILL STOP FOR AS LONG AS IT TAKES TO CALM DOWN AND UNDERSTAND WHERE I AM AND WHERE I AM GOING.
