Some more details of the 777X have been revealed. The design team is taking the best features of the 777 and 787 and combining them for the
preliminary flight deck design. They plan to put the larger 787 displays, and is using a former 787 development cab at the Integrated Aircraft
Systems Laboratory in Seattle.
The current plan is to have the 787 Flight Control System (FCS), which unlike the 777 FCS operates on all three axes. The Current 777 FCS is known as
C*u, and uses speed control for longitudinal stability. The 787 system added a P Beta law for longitudinal control.
The wing fold mechanism will be standard on all aircraft, and will reduce the wing from 233 feet, down to 212 feet when folded. The crew will receive
multiple warnings on the wing fold, to let them know if they are folded or extended. The rule will be that the wingtips will be extended when the
aircraft passes the hold short line on the runway.
