Narrative:
During our descent from the flight levels, my first officer, who was new at our company, asked me if I wanted the in-range checklist much higher and earlier than normal. I said it was ok. However, I didn't reset my altimeter as the checklist called for because we were still so high. As we continued our descent to 6000 ft and then 4000 ft, we became very busy talking to our company trying to decide whether they wanted us to land in lnk or oma. The final decision was to land in lnk. The tower was closed and center gave us a different approach than we expected, which continued to keep us busy. The error in not resetting the altimeter wasn't noticed until I called for the before landing checklist. Deviation from the normal procedure of using the in-range checklist as the descent approachs FL180 was the main source of the problem. The checklist calls for the altimeter to be reset. Also, a heavy workload and pilot fatigue contributed to the error not being detected earlier. Proper timing of the checklist and more SOP's throughout our company would help prevent this occurrence from happening again.

Title: FA20 CREW NEGLECTED TO RESET ALTIMETER PASSING FL180 DURING DSCNT.
Narrative: DURING OUR DSCNT FROM THE FLT LEVELS, MY FO, WHO WAS NEW AT OUR COMPANY, ASKED ME IF I WANTED THE IN-RANGE CHKLIST MUCH HIGHER AND EARLIER THAN NORMAL. I SAID IT WAS OK. HOWEVER, I DIDN'T RESET MY ALTIMETER AS THE CHKLIST CALLED FOR BECAUSE WE WERE STILL SO HIGH. AS WE CONTINUED OUR DSCNT TO 6000 FT AND THEN 4000 FT, WE BECAME VERY BUSY TALKING TO OUR COMPANY TRYING TO DECIDE WHETHER THEY WANTED US TO LAND IN LNK OR OMA. THE FINAL DECISION WAS TO LAND IN LNK. THE TWR WAS CLOSED AND CTR GAVE US A DIFFERENT APCH THAN WE EXPECTED, WHICH CONTINUED TO KEEP US BUSY. THE ERROR IN NOT RESETTING THE ALTIMETER WASN'T NOTICED UNTIL I CALLED FOR THE BEFORE LNDG CHKLIST. DEV FROM THE NORMAL PROC OF USING THE IN-RANGE CHKLIST AS THE DSCNT APCHS FL180 WAS THE MAIN SOURCE OF THE PROB. THE CHKLIST CALLS FOR THE ALTIMETER TO BE RESET. ALSO, A HVY WORKLOAD AND PLT FATIGUE CONTRIBUTED TO THE ERROR NOT BEING DETECTED EARLIER. PROPER TIMING OF THE CHKLIST AND MORE SOP'S THROUGHOUT OUR COMPANY WOULD HELP PREVENT THIS OCCURRENCE FROM HAPPENING AGAIN.
