History wind
The HISTORY WIND is accessed on
ground from CLIMB WIND page via
HISTORY WIND prompt [1R] and
enables a quick insert of wind data,
provided data are similar to wind
forecast for the intended flight.
During descent, the FMS stores
measured wind at a maximum of four
flight levels: CRZ FL (FLXXX), FL250,
FL150, FL050 (provided that these
fixed flight levels are less than FLXXX).
History wind can then be used for the
next flight, as a basis for the climb
wind definition.
Wind at intended CRZ FL is shown
provided it is already inserted.
CRZ wind value is then interpolated or
limited by FL50 / MAX FL when
applicable.
See examples on pictures
INSERT prompt [6R] is not displayed
if:
−
No history winds are defined,
−
History winds have been selected (It
re-appears if CRZ FL is changed),

Wind uplink request is pending or a
wind uplink is pending (not inserted
or cancelled).
If an altitude on the History wind page
is below the previous destination
runway threshold, there is no history
wind recorded for that altitude; the
field is dashed.
History wind data are not deleted at
transition to DONE, after a NAV data
base cycle change, or after a DEP
airport change. They are only deleted
when overwritten during the descent of
the next flight leg.
