For a ventral exit, 12 additional passenger seats.

(iii) For a tailcone exit incorporating an opening in the pressure shell which is at least equivalent to a Type III emergency exit with respect to dimen-sions, step-up and step-downdistance, and with the top ofthe opening not less than 56 inches from the passenger compartment .oor, 15 additional passenger seats.
