Narrative:

I departed M82 after dark and after working a long week and a 13 hour day. The purpose of the flight was to maintain my IFR proficiency. Prior to departure I intended to set the altimeter to field elevation and then reset it to the huntsville, al, current altimeter setting once airborne. However, prior to departure, I mistakenly set the altimeter 1000 ft above field elevation and then failed to request the current altimeter setting at the time I copied my clearance after becoming airborne. The controller advised me that I was 4000 ft when I was reading 3000 ft. After receiving the correct altimeter setting, I immediately dsdned to the proper altitude. Like most pilots, I pride myself in following and demonstrating safe flight procedures. This problem would not have occurred if I had waited until I was rested.

Original NASA ASRS Text

Title: AN SMA FLYING TO BECOME MORE PROFICIENT WITH INST FLYING, USES THE WRONG ALTIMETER SETTING AND FLIES 1000 FT FROM ASSIGNED ALT IN HSV, AL, AIRSPACE.

Narrative: I DEPARTED M82 AFTER DARK AND AFTER WORKING A LONG WK AND A 13 HR DAY. THE PURPOSE OF THE FLT WAS TO MAINTAIN MY IFR PROFICIENCY. PRIOR TO DEP I INTENDED TO SET THE ALTIMETER TO FIELD ELEVATION AND THEN RESET IT TO THE HUNTSVILLE, AL, CURRENT ALTIMETER SETTING ONCE AIRBORNE. HOWEVER, PRIOR TO DEP, I MISTAKENLY SET THE ALTIMETER 1000 FT ABOVE FIELD ELEVATION AND THEN FAILED TO REQUEST THE CURRENT ALTIMETER SETTING AT THE TIME I COPIED MY CLRNC AFTER BECOMING AIRBORNE. THE CTLR ADVISED ME THAT I WAS 4000 FT WHEN I WAS READING 3000 FT. AFTER RECEIVING THE CORRECT ALTIMETER SETTING, I IMMEDIATELY DSDNED TO THE PROPER ALT. LIKE MOST PLTS, I PRIDE MYSELF IN FOLLOWING AND DEMONSTRATING SAFE FLT PROCS. THIS PROB WOULD NOT HAVE OCCURRED IF I HAD WAITED UNTIL I WAS RESTED.
