Narrative:

I was flying the aircraft from syr to pit and we were cleared to FL220 out of 17000'. It was turbulent and we were climbing through a cloud layer. The captain was adjusting the rdar, which was not familiar to us. The altimeter setting at the airport we had just left was 29.25, and due to the preoccupation with the radar, I did not reset the altimeter to 29.92 through 18000'. The autoplt was on, and as the aircraft started to level off, the captain informed me about the altimeter setting. I immediately reset the altimeter and returned to FL220. Nothing was said by ATC and we did not pass the assigned altitude by very much. One thing that might have prevented this situation is to have standardized radar in the same aircraft type. Also developing a new procedure that when an aircraft is assigned a flight level from an altitude below 18000', it is issued as: 'climb and maintain FL220, check altimeter.'

Title: FLT CREW FAILED TO RESET ALTIMETER PASSING THROUGH 18000', OVERSHOT ASSIGNED ALT OF FL220.

Narrative: I WAS FLYING THE ACFT FROM SYR TO PIT AND WE WERE CLRED TO FL220 OUT OF 17000'. IT WAS TURBULENT AND WE WERE CLBING THROUGH A CLOUD LAYER. THE CAPT WAS ADJUSTING THE RDAR, WHICH WAS NOT FAMILIAR TO US. THE ALTIMETER SETTING AT THE ARPT WE HAD JUST LEFT WAS 29.25, AND DUE TO THE PREOCCUPATION WITH THE RADAR, I DID NOT RESET THE ALTIMETER TO 29.92 THROUGH 18000'. THE AUTOPLT WAS ON, AND AS THE ACFT STARTED TO LEVEL OFF, THE CAPT INFORMED ME ABOUT THE ALTIMETER SETTING. I IMMEDIATELY RESET THE ALTIMETER AND RETURNED TO FL220. NOTHING WAS SAID BY ATC AND WE DID NOT PASS THE ASSIGNED ALT BY VERY MUCH. ONE THING THAT MIGHT HAVE PREVENTED THIS SITUATION IS TO HAVE STANDARDIZED RADAR IN THE SAME ACFT TYPE. ALSO DEVELOPING A NEW PROC THAT WHEN AN ACFT IS ASSIGNED A FLT LEVEL FROM AN ALT BELOW 18000', IT IS ISSUED AS: 'CLB AND MAINTAIN FL220, CHK ALTIMETER.'
