4.3.4. Wind Speed, Direction and Arrow (when enabled)
The Wind Direction Arrow, Wind Direction and Wind Speed are displayed in the lower
right portion of the Data Bar (Figure 4-36).
The Wind Speed has a range of 10 to 999 knots or mph, using the same unit of measure
as the Airspeed Indicator.
The Wind Direction Arrow (Figure 4-38) and Wind Direction have a range of 001° to
360°, using the same direction reference used by the Direction Indicator. The arrow
points in the direction of the wind and is displayed relative to the current direction of
ight. For example, if the current direction of ight is 360° and the wind is from 360°, the
arrow will point straight down on the display (a headwind blowing toward aircraft).
When the computed wind speed is below 10 knots or mph, (depending on aircraft
conguration) or if the wind data is out of range or invalid, the Wind Direction/Wind
Speed values are blank and the Wind Direction Arrow is removed.
4.3.5. Barometric Pressure Setting Display
The Barometric Pressure Setting Field is displayed on the upper right corner of the Data
Bar (Figure 4-36) and is pilot-adjustable, as discussed in Section 4.2.3.1. When the
Altitude Tape is disabled, the Barometric Pressure Setting eld remains visible. However,
an installer can disable the eld and remove it from the display. Section 4.2.3.1
provides complete information and step-by-step instructions for setting the barometric
pressure.

NOTE
The wind computations require a GPS-provided
ground track and ground speed to compute the wind
direction and speed. If a GPS is not connected to the
PFD or the data is invalid, the Wind Direction/Wind
Speed is dashed and the Wind Direction Arrow is
removed.
