D-model (two-seat variant)

The D-model (two-seat variant) is a version of a vehicle, aircraft, or device designed specifically for two people—such as a pilot and a passenger or instructor and learner. It typically features a streamlined design optimized for maneuverability or performance, with controls accessible to both occupants. This configuration allows for tandem (one behind the other) or side-by-side seating, enabling direct communication and collaboration. The D-model is often used in training, recreation, or specialized operations where a smaller, more agile setup is advantageous. Overall, it provides an efficient, compact platform for dual occupancy purposes.
