[edit] Design and development

The M-311 is a small tandem two-seat shoulder-wing monoplane with a retractable tricycle landing gear, powered by a single Pratt & Whitney Canada JT15D-5C turbofan. It is based on the earlier S-211, with the addition of both structural and equipment improvements. The airframe has been strengthened, and a glass cockpit and modern avionics have been added. As a basic trainer, the aircraft is designed to complement the Aermacchi M-346 advanced trainer. The aircraft was designed with a secondary close air support capability with five underwing hardpoints.

The prototype aircraft first flew in June 2005.^[1]

In April 2008, Alenia and ENAER of Chile signed an agreement to jointly manufacture and sell the M-346 and M-311 in South America.

On 28 May 2008, Boeing and Alenia signed a joint agreement to cooperate on marketing, sales, training and product support for both the M-346 and M-311.^[2][3]
