Narrative:

While taxiing south on taxiway a from ramp beneath tower, the dogleg turn to taxiway B was missed due to reduced visibility conditions caused by blowing snow which was gusting up to 25 KTS out of the northwest. When the error was realized at the intersection of taxiway a, F, and runway 35, we informed the controller we had missed the turn on taxiway B and would require a 180 degree turn to get back to it. After assessment of the conditions at our location, I opted to inform the controller we would need to continue down taxiway F and taxi on runway 27 to get back to taxiway B. This was approved and we crossed runway 35 continuing on taxiway F, turned left onto runway 27 and proceeded again across runway 35 to taxiway B. At this point the controller advised hold short of runway 35 and we replied 'we just crossed runway 35.' the controller seemed confused of our location and asked our position at which we replied 'we are on taxiway B, south.' still not sure of our position, she commanded a go around of a cheyenne turboprop if they had not landed. They had landed and passed off our left as we proceeded to runway 35 south on taxiway B. The cause of this problem was that the ground controller had thought we turned west on taxiway F and did not immediately inform us she was unsure O four position. We did repeatedly inform her of our progress and location, however, did not specifically use magnetic direction while reporting our movement. We were informed of her inability to see us too late for us to realize the need for more specific updates as to our progress and location. In closing, in reduced visibility sits communication between the controllers and pilots must be much more specific to avoid any possibility of confusion as to the location of aircraft movement on the field.

Title: UNAUTH RWY ENTRY XING OP.

Narrative: WHILE TAXIING S ON TXWY A FROM RAMP BENEATH TWR, THE DOGLEG TURN TO TXWY B WAS MISSED DUE TO REDUCED VISIBILITY CONDITIONS CAUSED BY BLOWING SNOW WHICH WAS GUSTING UP TO 25 KTS OUT OF THE NW. WHEN THE ERROR WAS REALIZED AT THE INTXN OF TXWY A, F, AND RWY 35, WE INFORMED THE CTLR WE HAD MISSED THE TURN ON TXWY B AND WOULD REQUIRE A 180 DEG TURN TO GET BACK TO IT. AFTER ASSESSMENT OF THE CONDITIONS AT OUR LOCATION, I OPTED TO INFORM THE CTLR WE WOULD NEED TO CONTINUE DOWN TXWY F AND TAXI ON RWY 27 TO GET BACK TO TXWY B. THIS WAS APPROVED AND WE CROSSED RWY 35 CONTINUING ON TXWY F, TURNED L ONTO RWY 27 AND PROCEEDED AGAIN ACROSS RWY 35 TO TXWY B. AT THIS POINT THE CTLR ADVISED HOLD SHORT OF RWY 35 AND WE REPLIED 'WE JUST CROSSED RWY 35.' THE CTLR SEEMED CONFUSED OF OUR LOCATION AND ASKED OUR POS AT WHICH WE REPLIED 'WE ARE ON TXWY B, S.' STILL NOT SURE OF OUR POS, SHE COMMANDED A GAR OF A CHEYENNE TURBOPROP IF THEY HAD NOT LANDED. THEY HAD LANDED AND PASSED OFF OUR L AS WE PROCEEDED TO RWY 35 S ON TXWY B. THE CAUSE OF THIS PROB WAS THAT THE GND CTLR HAD THOUGHT WE TURNED W ON TXWY F AND DID NOT IMMEDIATELY INFORM US SHE WAS UNSURE O FOUR POS. WE DID REPEATEDLY INFORM HER OF OUR PROGRESS AND LOCATION, HOWEVER, DID NOT SPECIFICALLY USE MAGNETIC DIRECTION WHILE RPTING OUR MOVEMENT. WE WERE INFORMED OF HER INABILITY TO SEE US TOO LATE FOR US TO REALIZE THE NEED FOR MORE SPECIFIC UPDATES AS TO OUR PROGRESS AND LOCATION. IN CLOSING, IN REDUCED VISIBILITY SITS COM BTWN THE CTLRS AND PLTS MUST BE MUCH MORE SPECIFIC TO AVOID ANY POSSIBILITY OF CONFUSION AS TO THE LOCATION OF ACFT MOVEMENT ON THE FIELD.
