Narrative

ENRTE FROM ATL TO GTR. I WAS PNF THIS LEG; AND WAS WORKING THE RADIOS. WE WERE BEING WORKED BY ZTL ON 127.30 JUST W OF BHM. CTR GAVE US A XING RESTR OF WHAT I AM SURE I READ BACK AS '45 MI E OF IGB AT 11000 FT.' I SET 11000 FT IN THE ALT ALERTER AND MY FO AND I READ THE ALT TO ONE ANOTHER. NO MORE DISCUSSION OCCURRED BTWN THE FO AND I ABOUT THE ALT RESTR. THERE WERE SEVERAL CELLS PAINTING ON THE RADAR AHEAD AND WE HAD BEEN TALKING ABOUT THE WX AND I HAD FREQUENTLY BEEN LISTENING TO AWOS TO TRY TO FIND A TREND IN OUR DEST WX. PASSING THROUGH ABOUT 14000 FT; ZTL SWITCHED US TO COLUMBUS APCH. THE FREQ WAS NOT IN USE SO WE SWITCHED BACK TO ATL ON 127.30. HE SAID STAND-BY; SO WE CONTINUED OUR DSCNT. WE MADE THE 45 MI AT 11000 FT RESTR AND CONTINUED TO MONITOR THE WX AND COMPLETE CHKLISTS; CALL IN-RANGE; ORDER FUEL; ETC. ZTL THEN ASKED IF WE WERE AT 12000 FT; AND I SAID 'NO; WE WERE CLRED TO 11000 FT; WE'RE LEVEL AT 11000 FT.' ZTL SAID 'THE CLRNC WAS TO 12000 FT BUT THAT'S OK; JUST STAY AT 11000 FT.'
