The total increase in altitude from 5200 feet to 6620 feet over that distance is 1420 feet. At a normal rate of climb (120 feet per nautical mile at this altitude), the maximum altitude that can be gained over that distance is 720 feet, which is 700 feet below the required MOCA. Thus, a MCA for fix ABC of 5900 feet MSL (700 feet above the MEA of the previous segment) will be published for fix ABC for traffic continuing into the airway segment concerned from that fix.
