Air Traffic Incident | Pilot Deviation |
Narrative:
Was on an IFR flight plan from atl to bhm, and about halfway to bhm I fell asleep. The autoplt was on, and the heading indicator was set on a due west heading, and the altitude was set at 8000 ft. I didn't wake up for 30-45 mins. When I woke up I was about 90 NM south of hli VOR. I couldn't get atl, or bhm ATC on the radio, so I tried mem, and it took 2 or 3 frequencys to finally make contact. I turned due north to point the airplane in the right direction, and climbed to 10000 ft for right altitude for direction of flight, and for better radio/navigation reception, and better fuel consumption. I didn't think I had enough fuel for bhm, so I chose to land at mem. I landed at mem with about 1 hour of fuel. Later I was supposed to call bhm tower about the incident, and they said it was a pilot deviation. I asked what that was, and he told me that I went beyond the IFR clearance limit. Filed/cleared to bhm, but didn't land at bhm, then went past bhm. The airspace was a class east airspace. Problem: lack of sleep. To correct the situation: get 6-8 hours sleep, keep oneself busy in the cockpit by altitude change, drink water, and open vents/air conditioning.
Original NASA ASRS Text
Title: MU2 CARGO PLT FELL ASLEEP INFLT DURING NIGHTTIME OP.
Narrative: WAS ON AN IFR FLT PLAN FROM ATL TO BHM, AND ABOUT HALFWAY TO BHM I FELL ASLEEP. THE AUTOPLT WAS ON, AND THE HEADING INDICATOR WAS SET ON A DUE W HEADING, AND THE ALTITUDE WAS SET AT 8000 FT. I DIDN'T WAKE UP FOR 30-45 MINS. WHEN I WOKE UP I WAS ABOUT 90 NM S OF HLI VOR. I COULDN'T GET ATL, OR BHM ATC ON THE RADIO, SO I TRIED MEM, AND IT TOOK 2 OR 3 FREQS TO FINALLY MAKE CONTACT. I TURNED DUE N TO POINT THE AIRPLANE IN THE RIGHT DIRECTION, AND CLBED TO 10000 FT FOR RIGHT ALT FOR DIRECTION OF FLT, AND FOR BETTER RADIO/NAV RECEPTION, AND BETTER FUEL CONSUMPTION. I DIDN'T THINK I HAD ENOUGH FUEL FOR BHM, SO I CHOSE TO LAND AT MEM. I LANDED AT MEM WITH ABOUT 1 HR OF FUEL. LATER I WAS SUPPOSED TO CALL BHM TWR ABOUT THE INCIDENT, AND THEY SAID IT WAS A PLTDEV. I ASKED WHAT THAT WAS, AND HE TOLD ME THAT I WENT BEYOND THE IFR CLRNC LIMIT. FILED/CLRED TO BHM, BUT DIDN'T LAND AT BHM, THEN WENT PAST BHM. THE AIRSPACE WAS A CLASS E AIRSPACE. PROB: LACK OF SLEEP. TO CORRECT THE SIT: GET 6-8 HRS SLEEP, KEEP ONESELF BUSY IN THE COCKPIT BY ALT CHANGE, DRINK WATER, AND OPEN VENTS/AIR CONDITIONING.
