The reporter was cleared into the airspace requiring 29 pt 92 set into the altimeter and then just prior to getting there his altitude was changed to just below FL180 requiring a current local altimeter setting. The reporter anticipating the higher altitude had already set in 29 pt 92 and had to remember to set it back.

Narrative:
Climb out off of plottsburg, ny, in route to dubois, PA. Upon handoff to ZBW I was cleared to FL180. After passing 15800 ft, I was then cleared to amended altitude of 16000 ft. Only seconds before I had reset the altimeter to 29.92. Upon leveling at 16000 ft the altimeter needed to be reset to the current barometric pressure. I would suggest that if a clearance to a flight level from a lower altitude is amended to a lower altitude, that the controller give the pilot the current altimeter setting, as a reminder, during heavy workloads, that the altimeter is set correctly.
Original NASA ASRS Text
Title: THE RPTR WAS CLRED INTO THE AIRSPACE REQUIRING 29 PT 92 SET INTO THE ALTIMETER AND THEN JUST PRIOR TO GETTING THERE HIS ALT WAS CHANGED TO JUST BELOW FL180 REQUIRING A CURRENT LCL ALTIMETER SETTING. THE RPTR ANTICIPATING THE HIGHER ALT HAD ALREADY SET IN 29 PT 92 AND HAD TO REMEMBER TO SET IT BACK.
Narrative: CLBOUT OFF OF PLOTTSBURG, NY, IN RTE TO DUBOIS, PA. UPON HDOF TO ZBW I WAS CLRED TO FL180. AFTER PASSING 15800 FT, I WAS THEN CLRED TO AMENDED ALT OF 16000 FT. ONLY SECONDS BEFORE I HAD RESET THE ALTIMETER TO 29.92. UPON LEVELING AT 16000 FT THE ALTIMETER NEEDED TO BE RESET TO THE CURRENT BAROMETRIC PRESSURE. I WOULD SUGGEST THAT IF A CLRNC TO A FLT LEVEL FROM A LOWER ALT IS AMENDED TO A LOWER ALT, THAT THE CTLR GIVE THE PLT THE CURRENT ALTIMETER SETTING, AS A REMINDER, DURING HVY WORKLOADS, THAT THE ALTIMETER IS SET CORRECTLY.
