ATR (Aerei da Trasporto Regionale) is the undisputed king of the regional turboprop market, a joint French-Italian venture that has perfected the art of short-haul efficiency. Since the 1980s, ATR has provided the ideal solution for connecting remote communities and serving "thin" regional routes where larger jets would be uneconomical. The ATR 42 and the stretched ATR 72 are the most successful regional turboprops in history, prized for their ability to operate from short, challenging runways while maintaining incredibly low fuel burn and carbon emissions. With their high-wing design and rugged landing gear, ATRs are the lifeline of islands, mountain regions, and rural networks across every continent.
