Push – selects WIND page for the selected waypoint.

Note: ETA and estimated fuel calculations assume a direct flight across route
discontinuities.
Push – transmits a datalink request for wind and descent forecast data.
Flight crew may enter up to four altitudes on any wind page to qualify the request.
Wind Data
The FMC uses wind data to improve performance prediction accuracy. Wind data
includes altitude and direction/speed.
The FMC applies the first entered wind data to all waypoints in the flight plan.
Wind data entered at another waypoint (at the same altitude) changes wind data
downtrack from the second entered waypoint either to the end of the track, or to
the next entered wind. The wind data before the second entered waypoint does not
change. Therefore, enter wind data for waypoints closest to the airplane, then enter
wind data for waypoints downtrack from the airplane.
For example: at FL 350, 100°/085 is entered at waypoint OED. All waypoints in
the route have the OED wind data. Then, additional wind data entered at OAK
changes the wind data at OAK and through the end of the route.
