For a leg of 290 NM, with 20 pax and 3 crew, I figure a takeoff weight of 15417 kg. At an airport elevation of 5500 feet, that requires 5200 feet of dry runway at 30 deg C air temp. I haven't got the wet runway details, but adding 15% for wet conditions makes the length required 5980 feet. So the ERJ 135ER should be able to safely stop within the 7000 feet ASDA with an abort just before V1.
