Narrative:

I had filed IFR from medford to redding. When I reached the end of the taxiway, the tower informed me that there would be a 10 min delay. Since the WX was clear, I asked medford tower if I could climb out in VFR conditions and maintain my own separation. The tower granted my request and cleared me for takeoff. Before I rolled out onto the runway, I asked the tower if I could climb out on the brute 1 departure, talem transition. I wanted to be certain that the tower and I both agreed on what was going on. The tower confirmed that I could fly that routing but then said to climb on course. That implies a turnout in the general direction of flight. I was too fatigued or just too rushed to question the ambiguous clearance. So I departed and flew the SID. About 30 seconds later, the tower asked me where I was. I gave my position in relation to the transition I was flying. Then the tower said that I was supposed to have just done a downwind departure. I was pretty much on a right downwind anyway so I told them that. They switched me to departure and I still haven't figured out what happened. I telephoned the tower 2 days later and the controller said he wouldn't write me up and that he 'absolved me.' moral of the story: 1) clarify everything, including the previous clarification, 2) don't get rushed, 3) don't fly when fatigued.

Title: A CORP SMA PLT ASKED TO FLY A PUBLISHED SID IN VMC. THE TWR CTLR SAID TO CLB ON COURSE. THE SMA FLEW THE SID AND THE TWR BERATED HER FOR NOT TURNING DOWNWIND.

Narrative: I HAD FILED IFR FROM MEDFORD TO REDDING. WHEN I REACHED THE END OF THE TAXIWAY, THE TWR INFORMED ME THAT THERE WOULD BE A 10 MIN DELAY. SINCE THE WX WAS CLR, I ASKED MEDFORD TWR IF I COULD CLB OUT IN VFR CONDITIONS AND MAINTAIN MY OWN SEPARATION. THE TWR GRANTED MY REQUEST AND CLRED ME FOR TKOF. BEFORE I ROLLED OUT ONTO THE RWY, I ASKED THE TWR IF I COULD CLB OUT ON THE BRUTE 1 DEP, TALEM TRANSITION. I WANTED TO BE CERTAIN THAT THE TWR AND I BOTH AGREED ON WHAT WAS GOING ON. THE TWR CONFIRMED THAT I COULD FLY THAT ROUTING BUT THEN SAID TO CLB ON COURSE. THAT IMPLIES A TURNOUT IN THE GENERAL DIRECTION OF FLT. I WAS TOO FATIGUED OR JUST TOO RUSHED TO QUESTION THE AMBIGUOUS CLRNC. SO I DEPARTED AND FLEW THE SID. ABOUT 30 SECONDS LATER, THE TWR ASKED ME WHERE I WAS. I GAVE MY POS IN RELATION TO THE TRANSITION I WAS FLYING. THEN THE TWR SAID THAT I WAS SUPPOSED TO HAVE JUST DONE A DOWNWIND DEP. I WAS PRETTY MUCH ON A R DOWNWIND ANYWAY SO I TOLD THEM THAT. THEY SWITCHED ME TO DEP AND I STILL HAVEN'T FIGURED OUT WHAT HAPPENED. I TELEPHONED THE TWR 2 DAYS LATER AND THE CTLR SAID HE WOULDN'T WRITE ME UP AND THAT HE 'ABSOLVED ME.' MORAL OF THE STORY: 1) CLARIFY EVERYTHING, INCLUDING THE PREVIOUS CLARIFICATION, 2) DON'T GET RUSHED, 3) DON'T FLY WHEN FATIGUED.
