Narrative:

I was taxiing aircraft #1 from the south end of the ramp to runway 20 for takeoff at ZZZ. As I left the ramp; I announced my taxi intentions after hearing aircraft #2 announce their intentions to depart the airline ramp for runway 20. As I approached the taxiway coming out of the airline ramp; aircraft #2 was just pulling out of the chocks and had to make a few tight turns before they would be able to taxi onto taxiway a. I decided that there would be sufficient time and spacing to continue past the airline ramp before they would be in a position to enter taxiway a. As I was in the intersection of taxiway a and the airline terminal ramp; aircraft #2 decided to substantially increase speed around a sharp 90 degree right turn then a sharp 90 degree left turn onto taxiway a. I had to take evasive action to the right side of taxiway a almost to the point where my aircraft (aircraft #1) right landing gear was off the pavement. When questioned whether or not they saw aircraft #1; the response was that they didn't hear me on the radio. Aircraft #1 was clearly in a position that aircraft #2 could have seen it during their maneuvering onto taxiway a. The crew of aircraft #2 did not show any concern for the situation. I would like to recommend that operators ensure that their flight crews be more aware of their situational awareness while conducting ground operations. Especially at uncontrolled airports. In the future; I will not assume that another aircraft has me in sight or that they will continue to taxi at their present speed when estimating whether or not to continue my taxi even if I clearly have the right-of-way.

Title: C208 DEPARTING RAMP AT NON TOWERED ARPT HAS CLOSE ENCOUNTER WITH ACR DH8 ENTERING THE TXWY AT ANOTHER INTERSECTION.

Narrative: I WAS TAXIING ACFT #1 FROM THE S END OF THE RAMP TO RWY 20 FOR TKOF AT ZZZ. AS I LEFT THE RAMP; I ANNOUNCED MY TAXI INTENTIONS AFTER HEARING ACFT #2 ANNOUNCE THEIR INTENTIONS TO DEPART THE AIRLINE RAMP FOR RWY 20. AS I APCHED THE TXWY COMING OUT OF THE AIRLINE RAMP; ACFT #2 WAS JUST PULLING OUT OF THE CHOCKS AND HAD TO MAKE A FEW TIGHT TURNS BEFORE THEY WOULD BE ABLE TO TAXI ONTO TXWY A. I DECIDED THAT THERE WOULD BE SUFFICIENT TIME AND SPACING TO CONTINUE PAST THE AIRLINE RAMP BEFORE THEY WOULD BE IN A POS TO ENTER TXWY A. AS I WAS IN THE INTXN OF TXWY A AND THE AIRLINE TERMINAL RAMP; ACFT #2 DECIDED TO SUBSTANTIALLY INCREASE SPD AROUND A SHARP 90 DEG R TURN THEN A SHARP 90 DEG L TURN ONTO TXWY A. I HAD TO TAKE EVASIVE ACTION TO THE R SIDE OF TXWY A ALMOST TO THE POINT WHERE MY ACFT (ACFT #1) R LNDG GEAR WAS OFF THE PAVEMENT. WHEN QUESTIONED WHETHER OR NOT THEY SAW ACFT #1; THE RESPONSE WAS THAT THEY DIDN'T HEAR ME ON THE RADIO. ACFT #1 WAS CLEARLY IN A POS THAT ACFT #2 COULD HAVE SEEN IT DURING THEIR MANEUVERING ONTO TXWY A. THE CREW OF ACFT #2 DID NOT SHOW ANY CONCERN FOR THE SITUATION. I WOULD LIKE TO RECOMMEND THAT OPERATORS ENSURE THAT THEIR FLT CREWS BE MORE AWARE OF THEIR SITUATIONAL AWARENESS WHILE CONDUCTING GND OPS. ESPECIALLY AT UNCTLED ARPTS. IN THE FUTURE; I WILL NOT ASSUME THAT ANOTHER ACFT HAS ME IN SIGHT OR THAT THEY WILL CONTINUE TO TAXI AT THEIR PRESENT SPD WHEN ESTIMATING WHETHER OR NOT TO CONTINUE MY TAXI EVEN IF I CLEARLY HAVE THE RIGHT-OF-WAY.
