Human Factors
After completing a practice RNAV approach to Runway 5; I landed and was rolling out on Runway 5. During the rollout DHC-6 calls jump plane departing [intersecting runway] and obstructs the runway intersection. I yell 'look out' on radio as max braking was applied to prevent a collision. I was able to get the aircraft stopped in time. Pilot on jump plane said 'sorry thought you were clearing on Delta.'  After which point we exited on Delta; but had planned to roll to end of the runway. All appropriate radio calls had been made.'
The pilot of a PA24 reported a critical ground conflict during landing rollout when a Twin Otter began a takeoff roll on a crossing runway at a non-towered airport.
