As I stated the C402 is marginal for that runway. It would depend on winds, temperature and the weight of the aircraft. Light weight with a 15 knot headwind it would be fine. 88 degree day with calm winds and a moderate load I would not put my family onboard. Keep in mind that when you fly on a part 121 commercial airline they calculate takeoff performance so that if they lose a engine at the most critical point in the takeoff roll they can either stop on the remaining runway or continue the takeoff safely. Part 91 charter operators are not required to do that and can calculate performance based on both engines.
