Narrative:

After being de-iced, I signaled the ground marshaler that I was ready to taxi. My intent was to remain on the edge of the 'C' de-ice pad. Due to the snow accumulation, I inadvertently taxied the nose of the aircraft out onto taxiway B. There was an air carrier aircraft on taxiway B between taxiway V and taxiway T who did not believe that he could get by. As I was repositioning my aircraft out of the way and back into the pad, the ground controller changed his instructions and wanted me to pull back onto taxiway B and then a left onto taxiway B2 to allow other aircraft to pass. I pulled the aircraft back onto the center of the taxiway. My nosewheel got stuck in a drift of snow and would not effect a turn. I stopped and set the parking brake and requested that a tug be sent out to push me back onto the taxiway. A county official came out and believed that he could marshal me back into the center of the taxiway, but the nosewheel was still not able to turn. I set the parking brake again and once again requested the assistance of a tug. Snow had to be plowed and sand applied before the tug was able to pull us back onto the taxiway. This whole event would likely have been avoided had I held my position on the de-ice pad until receiving taxi clearance and that is certainly what I will do from now on. My only other recommendation is that some thought be given to expanding the airport page in pit to a larger fold-out version as many other larger airports have. This may have alerted me to a more accurate depiction of the 'C' de-ice pad and its proximity to taxiway B. This situation resulted in closing the 'C' de-ice pad as well as a portion of taxiway B. My concern was for the safety and well being of my passenger and crew as well as the aircraft.

Title: TAXIING FROM THE DE-ICE PAD WITHOUT A CLRNC, FLT CREW OF E145 GET STUCK IN SNOW DRIFTS AND BLOCK ACCESS TO DEP RWY AT PIT.

Narrative: AFTER BEING DE-ICED, I SIGNALED THE GND MARSHALER THAT I WAS READY TO TAXI. MY INTENT WAS TO REMAIN ON THE EDGE OF THE 'C' DE-ICE PAD. DUE TO THE SNOW ACCUMULATION, I INADVERTENTLY TAXIED THE NOSE OF THE ACFT OUT ONTO TXWY B. THERE WAS AN ACR ACFT ON TXWY B BTWN TXWY V AND TXWY T WHO DID NOT BELIEVE THAT HE COULD GET BY. AS I WAS REPOSITIONING MY ACFT OUT OF THE WAY AND BACK INTO THE PAD, THE GND CTLR CHANGED HIS INSTRUCTIONS AND WANTED ME TO PULL BACK ONTO TXWY B AND THEN A L ONTO TXWY B2 TO ALLOW OTHER ACFT TO PASS. I PULLED THE ACFT BACK ONTO THE CTR OF THE TXWY. MY NOSEWHEEL GOT STUCK IN A DRIFT OF SNOW AND WOULD NOT EFFECT A TURN. I STOPPED AND SET THE PARKING BRAKE AND REQUESTED THAT A TUG BE SENT OUT TO PUSH ME BACK ONTO THE TXWY. A COUNTY OFFICIAL CAME OUT AND BELIEVED THAT HE COULD MARSHAL ME BACK INTO THE CTR OF THE TXWY, BUT THE NOSEWHEEL WAS STILL NOT ABLE TO TURN. I SET THE PARKING BRAKE AGAIN AND ONCE AGAIN REQUESTED THE ASSISTANCE OF A TUG. SNOW HAD TO BE PLOWED AND SAND APPLIED BEFORE THE TUG WAS ABLE TO PULL US BACK ONTO THE TXWY. THIS WHOLE EVENT WOULD LIKELY HAVE BEEN AVOIDED HAD I HELD MY POS ON THE DE-ICE PAD UNTIL RECEIVING TAXI CLRNC AND THAT IS CERTAINLY WHAT I WILL DO FROM NOW ON. MY ONLY OTHER RECOMMENDATION IS THAT SOME THOUGHT BE GIVEN TO EXPANDING THE ARPT PAGE IN PIT TO A LARGER FOLD-OUT VERSION AS MANY OTHER LARGER ARPTS HAVE. THIS MAY HAVE ALERTED ME TO A MORE ACCURATE DEPICTION OF THE 'C' DE-ICE PAD AND ITS PROX TO TXWY B. THIS SIT RESULTED IN CLOSING THE 'C' DE-ICE PAD AS WELL AS A PORTION OF TXWY B. MY CONCERN WAS FOR THE SAFETY AND WELL BEING OF MY PAX AND CREW AS WELL AS THE ACFT.
