The MD 500E is a lightweight, piston-powered member of the MD 500 family, typically used for training, utility, and light observation; it generally offers the shortest range in this group and commonly seats a pilot plus three to four passengers depending on interior and mission fit. The MD 520N is in the same light single-engine class but replaces the conventional tail rotor with the NOTAR system, aiming for lower external noise and improved tail-rotor safety; its range is broadly similar to other light singles, and passenger capacity is typically comparable to the 500E. The MD 530F is a more powerful light single (often configured for high/hot performance), remaining in the same general category but usually providing better useful load and mission flexibility; seating is again usually in the four- to five-place range including the pilot. The MD 600N steps up to a larger light/medium single-engine utility category with NOTAR, typically offering more cabin volume, greater range, and seating around six to seven total. The MD 902 Explorer is a twin-engine NOTAR helicopter in the light/medium twin category, generally providing the greatest range and the highest typical seating, commonly around eight to nine total.
