This paper summarizes the preliminary design activity of a new cargo aircraft, including aerodynamic design and wind tunnel tests. A new concept of a dedicated cargo aircraft was evaluated by IAI. The fuselage shape was optimized for standard cargo containers. The resulting cross section was fairly rectangular. Other design requirements were - high speed, good ground performance, low fuel consumption and competitive price. These were met by choosing high power turboprop engines and by designing simple and efficient high lift devices. During the preliminary aerodynamic design phase two major aspects were emphasized: 1. Drag and lift goals 2. Good handling qualities, considering the high engine power effects
