Narrative:

Simply put, I took off at intersection D3 on runway 24, while cleared for takeoff on runway 6. Luckily the airport was not busy when I did this. There was no one in the traffic pattern, so no one had to divert. I am a low time pilot, and I just got my license. I believe this problem was caused by my tendency to get nervous and easily disoriented at unfamiliar airports. I believe it was a complete lack of orientation and judgement on my part. I had many resources available to avoid making such a mistake, including a map of the airport in the plane. I was nervous, and I saw the runway sign 24/6. I misinterped it to mean that runway 6 was to the right, instead of the beginning of runway 6 was to the right. To prevent this from occurring in the future, I will not accept intersection departures at unfamiliar airports. Additionally, if I am the least bit confused I will xchk my decisions using a different source of information. There were so many ways I should have caught this mistake before it happened.

Title: A C172 PVT PLT PERFORMS AN INTXN TKOF IN AN OPPOSITE DIRECTION THAN CLRED, ON RWY 24 VERSUS RWY 6 AT GRB, WI.

Narrative: SIMPLY PUT, I TOOK OFF AT INTXN D3 ON RWY 24, WHILE CLRED FOR TKOF ON RWY 6. LUCKILY THE ARPT WAS NOT BUSY WHEN I DID THIS. THERE WAS NO ONE IN THE TFC PATTERN, SO NO ONE HAD TO DIVERT. I AM A LOW TIME PLT, AND I JUST GOT MY LICENSE. I BELIEVE THIS PROB WAS CAUSED BY MY TENDENCY TO GET NERVOUS AND EASILY DISORIENTED AT UNFAMILIAR ARPTS. I BELIEVE IT WAS A COMPLETE LACK OF ORIENTATION AND JUDGEMENT ON MY PART. I HAD MANY RESOURCES AVAILABLE TO AVOID MAKING SUCH A MISTAKE, INCLUDING A MAP OF THE ARPT IN THE PLANE. I WAS NERVOUS, AND I SAW THE RWY SIGN 24/6. I MISINTERPED IT TO MEAN THAT RWY 6 WAS TO THE R, INSTEAD OF THE BEGINNING OF RWY 6 WAS TO THE R. TO PREVENT THIS FROM OCCURRING IN THE FUTURE, I WILL NOT ACCEPT INTXN DEPS AT UNFAMILIAR ARPTS. ADDITIONALLY, IF I AM THE LEAST BIT CONFUSED I WILL XCHK MY DECISIONS USING A DIFFERENT SOURCE OF INFO. THERE WERE SO MANY WAYS I SHOULD HAVE CAUGHT THIS MISTAKE BEFORE IT HAPPENED.
