Ту-154 is a three-engine medium-range narrow-body airliner designed in the mid-1960s and manufactured by Tupolev. A version with a new, stronger wing, designated Tu-154B, went into production in 1975. It also had an extra fuel tank in fuselage, extra emergency exits in the tail, increased passenger capacity, and increased the maximum take-off weight. As long as the airplane had the NK-8-2U engines the only way to improve the economics of the airplane was to spread costs across more seats. The Tu-154B-1 carried 160 passengers. This version also had some minor modifications to fuel system, avionics, air conditioning, landing gear. Tu-154B-2 is minor modernization of Tu-154B-1. The airplane with increased Max. take-off weight was designed to be converted from the 160 passenger version to a 180 passenger version by removing the galley.
