Boeing Completes Natural Icing Flight Tests for 777X and 737-10
Boeing recently flew its upcoming 777-9 and 737-10 aircraft into supercooled clouds to evaluate handling characteristics during natural ice accumulation. Flight crews targeted up to two inches of buildup on critical aerodynamic surfaces, successfully verifying that both airframes maintain stable performance in adverse weather. Test pilots reported the aircraft flew so normally that the accretion was barely noticeable without onboard instrumentation. For aspiring airline crews, these milestones signal that next-generation flight controls are becoming increasingly resilient to hazardous atmospheric conditions.
