Requirements — Airbus A350-XWB Passenger Aircraft Requirements [general]

• The aircraft shall achieve a minimum market share of 25% in the long-haul widebody segment within 5 years of entry into service.
• The aircraft shall demonstrate a 20% improvement in fuel efficiency per passenger-kilometer compared to previous generation aircraft in its class.
• The aircraft shall be certified by EASA and FAA for passenger operations prior to its scheduled entry into service.
• The aircraft shall be capable of accommodating between 300 and 440 passengers in a typical three-class configuration.
• The aircraft shall be a twin-engine, widebody, long-haul passenger aircraft with a maximum range of at least 8,100 nautical miles.
• The aircraft shall incorporate a full fly-by-wire flight control system with redundant channels for all primary flight surfaces.
• The aircraft shall utilize an Integrated Modular Avionics (IMA) architecture compliant with ARINC 653 and interconnected via an AFDX (ARINC 664) data network.
• The aircraft primary airframe structure shall be composed of at least 50% advanced composite materials by weight.
• The aircraft shall be powered by a 230 VAC variable-frequency electrical power generation and distribution system.
• The aircraft shall maintain cabin pressure altitude below 6,000 feet at a cruising altitude of 40,000 feet.
• The flight control system shall enable precise control of aircraft pitch, roll, and yaw axes.
• The IMA system shall provide fault-tolerant execution of flight-critical applications.
• The aircraft shall provide autonomous navigation capabilities using multiple redundant sensor inputs.
• The Fuel Control System (FCS) shall manage engine fuel flow to achieve optimal thrust and fuel efficiency.
• The aircraft shall provide an emergency evacuation system capable of evacuating all passengers and crew.
• The aircraft shall provide an in-flight entertainment (IFE) system for passenger use.
• The aircraft wingspan shall not exceed 65 meters.
• The unit recurring cost (URC) of the aircraft shall not exceed $300 million (2024 USD).
• The development schedule shall not exceed 8 years from program launch to first customer delivery.
• The aircraft shall be capable of operating from runways with a minimum length of 2,000 meters at sea level, ISA conditions, MTOW.
• Failure to achieve EASA/FAA dual certification within the planned schedule.
• Integration complexity of the IMA and AFDX network leading to unforeseen system interactions or performance issues.
• Supply chain disruption for advanced composite materials or critical avionics components.
• The regulatory framework for aircraft certification (EASA CS-25, FAA FAR Part 25) will remain largely stable during the development program.
• Qualified engineering talent and manufacturing capabilities for advanced composite structures are available at competitive costs.
• The AFDX (ARINC 664) and ARINC 653 standards will continue to be the industry-preferred architecture for integrated avionics.
