6L -- When entry of any data on the WIND/TEMP page occurs, the
D
CLEAR prompt at 6L is displayed, as shown in Figure 5--15.
Selection of this prompt clears all entries on the page and returns
the default values displayed when the page was first accessed.
6R -- When entry of a valid wind/temperature occurs, the ENTER
D
prompt at 6R is displayed, as shown in Figure 5--15. A valid
wind/temperature entry requires entry of an altitude and entry of
wind and/or temperature. When an entry is valid, the data is
displayed in reverse video and the ENTER prompt is displayed.
WIND AND TEMPERATURE MODEL BLENDING
The FMS wind and temperature model blends wind and temperature
entries with the current position sensed wind and temperature. The
sensed wind and temperature are blended in proportion to the distance
away from the aircraft. For example, at present position, sensed wind
and temperature are blended at 100%. At 350 NM, sensed is blended
50% and entered at 50%. For other distances, wind and temperatures
are blended proportionately.
