TWA060

Another CDU Issue

Recommended Posts

Guys,I just completed a short trial flight at FL210 just to see how the 777 flies. Great flight with very few issues that weren't operator error! Thanks for a great aircraft.I did have an error with the CDU that may need to be addressed. I was at FL210 and entered a crossing restriction of 250/10000 for a waypoint and hit Activate. The restriction was added to the waypoint but the subsequent waypoint altitudes weren't recalculated. They stayed at FL210. Also the prior waypoint was only 9nm ahead of the waypoint with the restriction and it also stayed at FL210. It seems to me that the subsequent waypoint altitudes should be adjusted based on the new restriction as well as any waypoints between the newly calculated T/D and the restricted waypoint.I haven't flown a second flight to try to reproduce - maybe tomorrow.
