SEATTLE-<\/strong> The Boeing 777-9<\/a> team, operating at Clinton Sherman Airport (CSM) in Oklahoma, battled fierce winds, torrential hail, and thunderstorms to complete critical braking certification tests for Boeing\u2019s new widebody jet, operated by airlines like Emirates (EK) and Qatar Airways (QR).<\/p>\n\n\n\n

Over 63 days, more than double the planned duration, the team, led by test director Madison Strauss, conducted rigorous tests on the first 777-9<\/a> flight test airplane, WH001, relocating to Lubbock Preston Smith Airport (LBB) in Texas when weather disrupted operations, ensuring the world\u2019s largest twin-engine jet meets stringent safety standards.<\/p>\n\n\n\n

Boeing 777-9 Brake Certification<\/h2>\n\n\n\n

In early March, the 777-9 flight test team established operations at Clinton Sherman Airport (CSM) to evaluate brake and wheel performance under dry conditions.<\/p>\n\n\n\n

The first test airplane, WH001, underwent hard braking maneuvers to define operational limits, generating data for regulatory approval.<\/p>\n\n\n\n

Project pilot Heather Ross explained, \u201cWe test these extremes to know the airplane\u2019s boundaries, ensuring it meets our expectations and those of the regulator.\u201d<\/p>\n\n\n\n

Testing required calm winds below 10 knots (12 mph) and dry runways, conditions often absent during the Oklahoma spring. Madison Strauss noted, \u201cOur analysis team set tight wind limits to isolate brake performance from external factors.\u201d<\/p>\n\n\n\n

High winds frequently halted testing, prompting the team to fly to Lubbock (LBB)<\/a> for crosswind evaluations. Severe storms, including hail risks, forced two evacuations to protect the aircraft, significantly extending the 63 day timeline, far beyond the initial 30 day forecast.<\/p>\n\n\n\n

Complex Remote Operation<\/h2>\n\n\n\n

Remote testing demanded meticulous planning and a multi-disciplinary support network, both on-site and at Boeing\u2019s Seattle hub, Boeing Field (BFI).<\/p>\n\n\n\n

Flight test maintenance specialist Marlon Mercado highlighted logistical challenges: \u201cSecuring the right equipment, tools, and parts for 24 hour operations, split into two 12 hour shifts, is the toughest part.\u201d<\/p>\n\n\n\n
