Narrative:

Departed gso as flight gso-bna. Was given 2500 ft as initial altitude in clearance. Departed in VFR conditions and proceeded to climb. Captain was flying aircraft. As first officer I was completing climb checks when I was directed to contact departure. At 1500 ft I advised captain '1.5 for 2.5' after verbally completing checklist I checked on with departure. 'Flight out of 2300 ft for 2500 ft.' at about this same time we were entering freezing precipitation and going IMC. Snow was rather thick. Captain reached up to activate anti-ice/deice for engines and propellers. As a result busted altitude. Occurrence was result of many things happening at the same time and not enough attention to altitude. Captain indicated that glancing at altimeter set window he saw a '5' and thought 5000 ft out of habit.

Title: ALTDEV ALT OVERSHOT DURING INITIAL CLB IN NIGHT OP.

Narrative: DEPARTED GSO AS FLT GSO-BNA. WAS GIVEN 2500 FT AS INITIAL ALT IN CLRNC. DEPARTED IN VFR CONDITIONS AND PROCEEDED TO CLB. CAPT WAS FLYING ACFT. AS FO I WAS COMPLETING CLB CHKS WHEN I WAS DIRECTED TO CONTACT DEP. AT 1500 FT I ADVISED CAPT '1.5 FOR 2.5' AFTER VERBALLY COMPLETING CHKLIST I CHKED ON WITH DEP. 'FLT OUT OF 2300 FT FOR 2500 FT.' AT ABOUT THIS SAME TIME WE WERE ENTERING FREEZING PRECIPITATION AND GOING IMC. SNOW WAS RATHER THICK. CAPT REACHED UP TO ACTIVATE ANTI-ICE/DEICE FOR ENGS AND PROPS. AS A RESULT BUSTED ALT. OCCURRENCE WAS RESULT OF MANY THINGS HAPPENING AT THE SAME TIME AND NOT ENOUGH ATTN TO ALT. CAPT INDICATED THAT GLANCING AT ALTIMETER SET WINDOW HE SAW A '5' AND THOUGHT 5000 FT OUT OF HABIT.
