Entered Speed deviation alert threshold
calculations while on the ground.
Entered waypoint alert time in seconds
prior to waypoint arrival or leg switch.
Entered cross track deviation alert
threshold (nautical miles).
TERMINAL, or APPROACH.
(c) Entry and Use of Waypoint Wind. On
the Flight Plan Waypoint page, a predicted wind can
be entered for each waypoint in the flight plan. Refer
to Figure 3C-44 and Table 3C-35. Wind entries are
used with current True Airspeed to provide improved
prediction for waypoint ETA and ETE as shown on the
Lateral Steer page, Figure 3C-42.
When wind is entered at a future waypoint, the
wind entry will be fixed at the entry waypoint and
propagate through the flight plan to all subsequent
waypoints. When new waypoints are inserted into the
flight plan, the default wind for the new waypoint will
be based on the previous waypoints wind entry.
When no wind entry is provided, the FMS uses current
wind for predicted arrivals at the waypoint. The active
waypoint wind will show the current wind conditions
and entry is not permitted. The wind for history
waypoints is the actual wind measured at waypoint
passage, and entry is not permitted. Wind direction is
entered in the direction from which the wind is blowing.
When transferring a flight plan from the alternate
to the active flight plan, the waypoint wind entered in
the alternate flight plan will be retained in the active
flight plan definition.
Command Limits and Crosstrack Deviation Alerting.
The bank command limit for the FMS steering and
flight plan leg switching is controlled by the crew
entering a value on the Navigation Configuration page.

T indicates RTA assigned to the waypoint.
Entering a and pressing this line select
key will delete the RTA at this waypoint.
The bank command limit is used by the FMS
guidance function to limit FMS commanded banks to
the entered threshold. Turn anticipation for waypoint
sequencing along the flight plan is adjusted according
to the limit specified to minimize overshoot conditions.
