EVERETT-<\/strong> Boeing<\/a> progresses toward 777X<\/a> certification, with recent crosswind tests at Lubbock Airport (LBB) marking a key milestone. The tests ensure the aircraft\u2019s performance in extreme winds for regulatory approval.<\/p>\n\n\n\n

The 777-9, the longest airliner built, aims for deliveries in 2026, with ongoing brake tests at Clinton-Sherman Airport (CSM) and reactivated flight tests for WH004.<\/p>\n\n\n\n

Boeing 777X Certification<\/h2>\n\n\n\n

Boeing\u2019s 777-9, the largest variant of the 777X family<\/a>, is undergoing rigorous testing to meet Federal Aviation Administration (FAA)<\/a> certification standards.<\/p>\n\n\n\n

In mid-March, the first test aircraft, WH001, completed crosswind testing at Lubbock Preston Smith International Airport (LBB) in Texas.<\/p>\n\n\n\n

According to Aviation Week<\/a>, these tests leveraged extreme weather conditions to evaluate the aircraft\u2019s controllability during takeoffs, landings, and maneuvers in winds up to 60 knots. <\/p>\n\n\n\n

At 252 feet 9 inches, the 777-9\u2019s length creates a significant empennage moment arm, requiring precise handling in crosswinds. <\/p>\n\n\n\n

FAA Part 23 mandates demonstrating controllability in a 90-degree crosswind at least 20% of stall speed, a critical requirement for the aircraft\u2019s safety and performance.<\/p>\n\n\n\n

Boeing\u2019s meteorologists planned the tests weeks in advance, identifying Lubbock\u2019s weather and runway layout as ideal. <\/p>\n\n\n\n
