Narrative:

On mar/xa/96 and mar/xb/96 respectively, I was flying as first officer on ab airlines flight xx. This was the third leg of a 5 leg trip denoted xy. The WX on both days was very cold and snowy with low ceilings and visibility in the early morning with improved ceiling and visibility in the late morning. During both days a lingering and persistent winter storm was passing through pennsylvania and the northeast corridor. On both days we required deicing with both type I and ii at most of our stops. This was the case at abe on our abe to bos leg. I'm not sure if on both days we deiced with type I and ii or just type I. But thorough deicing in compliance with company and FAA procedures and polices was completed. We had the aircraft clocks in synchronization with the station pacer computers, so that start times for deicing would be accurate with the deice crew, which it was on both days. We consulted our deice holdover time tables in the DHC8 pilot handbook and figured our holdover times correctly. On one of the 2 days departing from abe to bos, we may have taken off at a time close to the limit of our computed holdover time. But we did not exceed that time.

Title: GND DEICING HOLDOVER TIME QUESTIONABLE. MAY HAVE EXCEEDED TIME WHEN TAKING OFF.

Narrative: ON MAR/XA/96 AND MAR/XB/96 RESPECTIVELY, I WAS FLYING AS FO ON AB AIRLINES FLT XX. THIS WAS THE THIRD LEG OF A 5 LEG TRIP DENOTED XY. THE WX ON BOTH DAYS WAS VERY COLD AND SNOWY WITH LOW CEILINGS AND VISIBILITY IN THE EARLY MORNING WITH IMPROVED CEILING AND VISIBILITY IN THE LATE MORNING. DURING BOTH DAYS A LINGERING AND PERSISTENT WINTER STORM WAS PASSING THROUGH PENNSYLVANIA AND THE NE CORRIDOR. ON BOTH DAYS WE REQUIRED DEICING WITH BOTH TYPE I AND II AT MOST OF OUR STOPS. THIS WAS THE CASE AT ABE ON OUR ABE TO BOS LEG. I'M NOT SURE IF ON BOTH DAYS WE DEICED WITH TYPE I AND II OR JUST TYPE I. BUT THOROUGH DEICING IN COMPLIANCE WITH COMPANY AND FAA PROCS AND POLICES WAS COMPLETED. WE HAD THE ACFT CLOCKS IN SYNCHRONIZATION WITH THE STATION PACER COMPUTERS, SO THAT START TIMES FOR DEICING WOULD BE ACCURATE WITH THE DEICE CREW, WHICH IT WAS ON BOTH DAYS. WE CONSULTED OUR DEICE HOLDOVER TIME TABLES IN THE DHC8 PLT HANDBOOK AND FIGURED OUR HOLDOVER TIMES CORRECTLY. ON ONE OF THE 2 DAYS DEPARTING FROM ABE TO BOS, WE MAY HAVE TAKEN OFF AT A TIME CLOSE TO THE LIMIT OF OUR COMPUTED HOLDOVER TIME. BUT WE DID NOT EXCEED THAT TIME.
