4.4.5 Winds/Temps aloft
The EFD1000/500 MFD Winds /Temps Aloft screen displays the forecast wind vector
and temperature at the selected altitude above MSL on a basic weather map. Winds are
depicted as barbs up to a map range of 500 nm; for map ranges of 1000 nm and above
station identifier and temperatures may be omitted. (
Figure 4-26
)
When the map range is below 500 nm the wind direction is depicted by wind pointer
lines extending upwind from the reporting weather station (the small dot on the
bottom of the shaft). Wind speed is depicted by pennants or short lines (barbs) on the
upwind end of the shaft. Each short barb represents 5 kts, each long barb represents
10 kts and a pennant represents 50 kts. Wind pointer lines can depict winds up to 190
kts (3 pennants and 4 long barbs). The Winds Aloft legend provides a depiction of each
type of measurement. (
