To understand it better, we compiled the many indications that points to weight increase and ran them through our proprietary model to understand why and see what it means for the aircraft’s performance.
Weight increase is an evil that all aircraft programs battle with. Our analysis shows that 777X is no different.
Engine thrust is one of the areas which will be increased to mitigate increased weight. We give the latest status of GE9X thrust development, now beyond 105,000 lb.
A number of airframe changes have been made. We analyze their consequences and make predictions for future maximum weight increases.
