Human Factors
IFR flight plan filed TVL - ZZZ. 2 pilots. I was the designated SIC and the Pilot Flying for this flight. We elected to depart VFR and obtain our IFR clearance once airborne. We announced our taxi intentions for Runway 36. We noted a few aircraft in the area either landing or flying by the airport. As we held short of Runway 36 at intersection Bravo; we saw an aircraft on our TCAS at 1;700 feet AGL about 4 miles south of the airport heading toward the airport. I visually acquired the aircraft soon thereafter. After hearing no further traffic advisories from other aircraft; the PIC and I agreed to depart Runway 36. The PIC announced our intentions to depart Runway 36 and no further calls (from other aircraft) were initially heard. As we crossed the hold short line; the aircraft that we visually acquired earlier stated their intention to land Runway 36 and began descending. We immediately stopped the aircraft and told the other aircraft we were past the hold short line; but not on the runway surface. The other pilot acknowledged our location and continued their approach to landing. The PIC reiterated that we were already past the hold short line and the other pilot just acknowledged our location. No attempt to increase spacing through S-turns; a 360 or go around was made by the other pilot as we were stopped between the hold short line and the left edge of the runway surface (displaced threshold). Not knowing how fast the aircraft was going to approach the runway; we elected to stay put and maintain visual contact with the landing aircraft. As that aircraft landed; another aircraft (PC-12) announced their intentions to land while on a left base to final. Again; we announced we were past the hold short line but not on the runway surface. They acknowledged our location and continued to land while showing no attempts to increase spacing for us to move our aircraft. After the second aircraft landed; we departed Runway 36 without further incident.
Flight crew reported runway incursion and ground conflict with landing aircraft at TVL non-towered airport.
