737-400

The Boeing 737-400 is a MONOPLANE type aircraft designed for civil transport and introduced to the global aviation scene in the mid-twentieth century. The aircraft completed its maiden flight in 1988, marking an important step in the technological development of its category.

Originally designed to meet the strict requirements of regional and international airlines, it complied with rigorous standards of operational efficiency, structural robustness, and passenger comfort in the cabin.

The overall production of this model represented a milestone in the industrial development of its manufacturer.

From an engineering perspective, the Boeing 737-400 stands out for a solid airframe, entirely made of metal or lightweight alloys, optimized to guarantee flight safety and excellent aerodynamic stability.

Thrust is provided by 2x CFM56-3, proven and efficient powerplants offering steady cruise performance. With an estimated range of 3800 km, it features an internal configuration capable of accommodating up to 188 passengers or the respective operational load.

The onboard avionics and control design facilitated piloting even under complex meteorological conditions.
