This aircraft, central to propulsion and avionics testing, has not flown since September 2024. <\/p>\n\n\n\n<p>The upcoming functional check flight, expected as early as January 15, 2025, will pave the way for the full resumption of the certification program.<\/p>\n\n\n\n<p>A seven-week labor strike in late 2024 further exacerbated the program&#8217;s delays, contributing to Boeing\u2019s decision to push initial deliveries to 2026. Despite these challenges, Boeing remains committed to advancing the 777X, a key part of its long-haul fleet offerings.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"682\" src=\"https:\/\/aviationa2z.com\/wp-content\/uploads\/2022\/07\/Boeing777xLarge-10-1024x682.jpg\" alt=\"\" class=\"wp-image-23134\" srcset=\"https:\/\/aviationa2z.com\/wp-content\/uploads\/2022\/07\/Boeing777xLarge-10-1024x682.jpg 1024w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2022\/07\/Boeing777xLarge-10-scaled-600x399.jpg 600w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2022\/07\/Boeing777xLarge-10-300x200.jpg 300w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2022\/07\/Boeing777xLarge-10-768x511.jpg 768w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2022\/07\/Boeing777xLarge-10-1536x1022.jpg 1536w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2022\/07\/Boeing777xLarge-10-2048x1363.jpg 2048w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2022\/07\/Boeing777xLarge-10-750x499.jpg 750w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2022\/07\/Boeing777xLarge-10-1140x759.jpg 1140w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Photo: Boeing<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-boeing-777x-certification-flights-overview\">Boeing 777X Certification Flights Overview<\/h2>\n\n\n\n<p>The 777X certification fleet consists of four aircraft, each contributing to specific aspects of the program:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>WH001<\/strong>: First flown in January 2020, this prototype has primarily conducted stability, control, and aerodynamic testing.
