Boeing Advances 777-9 Certification with Final Human Factors Simulator Evaluation Ahead of 2027 First Delivery

USA – Boeing has completed the fourth and final phase of simulator-based human factors evaluations for the 777-9 flight deck, involving more than 200 airline pilots from customer carriers across seven global locations over three years, as the manufacturer works toward first delivery in 2027 and FAA certification of the world's largest twin-engine jet.

• The 777-9 is the first Boeing airplane to use simulator evaluations with airline pilots to demonstrate compliance with updated human factors regulations governing flight deck design, issued by the FAA following the Aircraft Certification, Safety & Accountability Act of 2020.
• For the fourth phase, crews from five customer airlines participated in flight scenarios in Boeing's Seattle simulator, ranging from full gate-to-gate flights to partial scenarios evaluating specific design aspects. Boeing intentionally introduced system malfunctions during flight profiles, with crews responding in real time without prior knowledge of what was being tested.
• The multi-year evaluation program spanned four phases across seven locations (Dubai, Frankfurt, Gatwick, Hong Kong, Miami, Seattle, and Singapore), with approximately 70 flight scenarios developed, 118 days of testing, and more than 10,000 observer notes documented in the fourth phase alone, supported by over 800 hours of preparation across 150+ planning sessions.
• The 777-9 flight deck is designed for high commonality with the existing 777 and 787 Dreamliner, incorporating advancements including large-format displays with touchscreen capability, optional dual head-up displays, a redesigned pilot seat, and a unique control and indicator for the 777-9's folding wingtips.
• Boeing will submit data from the study to the FAA to support certification, with insights from the evaluation also intended to benefit future Boeing airplane programs.

Statements

• "This is the first time we're taking a look at the flight deck in its entirety against these new human factors regulations," said Captain Tanner Sims, Engineering Test Pilot at Boeing.
• "Each crew was completely naïve to what we were testing. We wanted their true, unbiased reaction to a particular situation," said Captain Tanner Sims, Engineering Test Pilot at Boeing.
• "We were looking at everything – at the flight deck, checklists, alerting – it's all-encompassing," said Captain Gary Mandy, 777X Chief Technical Pilot at Boeing.
