The Tu-204SM is medium-range airliner, with a seating capacity of 210 passengers, and 174 in a two-class layout. The plane targets the low-cost carrier market. This plane has been upgraded to meet relevant, and future Russian/International safety requirements, including new ICAO and Eurocontrol standards which includes all environmental parameters, noise, and emission levels.
The Tu-204SM will have a compact airframe. However the Tu-204SM will feature many design and aerodynamic similarities to the Tu-204-100/100E/100V. The aircraft's flight navigation system and avionics will permit a two-pilot crew.
The Tu-204SM is an upgraded variant of the Tu-204-100/300 upgrades include new TA-18 APU-200, new equipment, improved streamlining, and general aerodynamic design with improved interiors. An advanced Flight Control System equipment (ASO-204/FMS) with automatic on board system maintenance and diagnostics will be featured. The cockpit is automated with wide LCD displays, and Heads-Up Displays (HUD). There will be improvements in power systems (APU), control, fire safety, fuel management and hydraulic systems, and the aircraft's certification is expected to take place in 2011.
The Tu-204SM will implement an "E-Pilot" concept, and feature new flight control and navigation equipment, a new VSUPT-85-204 computer, a new throttle management system, and a SCD-100-1 Computer Flight Management System. There will also be these following upgrades so the aircraft would be in compliance with international requirements and P-RNAV. The upgrades are a new system for measuring SIVD data, and a modern airplane equipment control system. It will also feature a KSEIS-204E electronic display and warning system. To also help simplify aircraft operations all controls are produced in English.
The uppgrades to passenger/interior accommodations includes new luggage shelves and under-floor compartment for large trunks, multi-colored LED lighting, sound-absorbing structures in the passenger cabin, audio and video displays for in-flight entertainment.
The Tu-204SM will feature advanced, and upgraded PS-90A2 engines, a unified twin-spool turbofan engine with a high bypass ratio. The PS-90A2 has a life cycle cost decreased by 35% with simultaneous increase in reliability by 50 to 100%.
The PS-90A2 will pass AP-33 aviation standards certification, harmonized with FAR Part 33 and JAR33. The price for one Tu-204SM is estimated at $40–47 million
