Can anyone tell which runway length is required for a Beech 1900 under "normal" circumstances, i.e. 75% of its max payload and fuel, sea level, normal pressure?

I am asking because I had a discussion with someone whether some of the smaller airports in the Britanny (Bretagne) part of France were accessible by scheduled B1900. Runway lengths are all around 700-900 meters, i.e. approx. 2100-2700 ft. I know there are other considerations, but I would just like to know for runway length.

Thanks
