Narrative:
I had departed M88 and was proceeding to the east under the bna arsa which begins at 2100'. While trying to enter data in my LORAN I let my altitude exceed 2100'. Upon discovering, I immediately lowered the nose of the aircraft. There was no conflict with other aircraft. Corrective action for future flts will be to proceed out of the arsa at 1500', thus giving a 600' safety margin and make any LORAN adjustments outside the 10 mi ring. Callback conversation with reporter revealed the following: advised reporter that arsa floor and ceiling altitudes belong to the airspace so he was already in the arsa before he lost altitude awareness and climbed. He said he was not aware of this and accepted the counseling with thanks. His incursion of the bna arsa was apparently not noted by ATC for he has heard nothing from them.
Original NASA ASRS Text
Title: LOW TIME PLT FLIES SMA AT ARSA FLOOR ALT BELIEVING HIMSELF TO BE UNDER THE ARSA, THEN LOSES ALT AWARENESS DOING OTHER TASK, CLIMBS 150', AND CONFESSES TO ARSA PENETRATION.
Narrative: I HAD DEPARTED M88 AND WAS PROCEEDING TO THE E UNDER THE BNA ARSA WHICH BEGINS AT 2100'. WHILE TRYING TO ENTER DATA IN MY LORAN I LET MY ALT EXCEED 2100'. UPON DISCOVERING, I IMMEDIATELY LOWERED THE NOSE OF THE ACFT. THERE WAS NO CONFLICT WITH OTHER ACFT. CORRECTIVE ACTION FOR FUTURE FLTS WILL BE TO PROCEED OUT OF THE ARSA AT 1500', THUS GIVING A 600' SAFETY MARGIN AND MAKE ANY LORAN ADJUSTMENTS OUTSIDE THE 10 MI RING. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: ADVISED RPTR THAT ARSA FLOOR AND CEILING ALTS BELONG TO THE AIRSPACE SO HE WAS ALREADY IN THE ARSA BEFORE HE LOST ALT AWARENESS AND CLBED. HE SAID HE WAS NOT AWARE OF THIS AND ACCEPTED THE COUNSELING WITH THANKS. HIS INCURSION OF THE BNA ARSA WAS APPARENTLY NOT NOTED BY ATC FOR HE HAS HEARD NOTHING FROM THEM.
