Hello guys,
I'm having a little problem with my NGX. It doesn't happen everytime, and some times it comeback to normal.
What happens is I'm entering the winds on the winds page and suddenly when I click for example R3 key to enter the wind for that way-point, the data doesn't get populated and the Exec button doesn't lit. I have to go to another page for that to happens. From that time on, it happens again with any data I want to change. Also I loose my vertical path and calculations and VNAV won't engage. On the legs page all time/FL data for all the waypoints are dashed, and i don't have any TD calculations.
Does someone encounter this?
Here are some screenshots.
EDIT: I just made the VNAV come back by adding a FL restriction into one of the waypoints at cruise. But if I do that, the FMC calculates the TD just after that waypoint, and in the case of the flight of the screenshots, almost 800 nm before!
