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 are invalid, the wind direction and
speed are dashed and the wind direction arrow
is removed.
4.4.5 Wind Speed, Direction, and Arrow (when enabled)
The Wind Speed, Direction, and Direction Arrow are displayed in the lower right portion
of the Data Bar. The Wind Speed has a range of 10–999 knots or mph, using the same
unit of measure as the Airspeed Indicator.
The Wind Direction and Arrow have a range of 001°–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 flight. For example, if the current
direction of flight is 360° and the wind is from 360°, the arrow will point straight down
on the display (a headwind blowing toward your aircraft).
When the computed wind speed is below 10 knots or mph (depending on aircraft
configuration) the wind speed and direction values are blank, and the wind arrow is
removed. If the wind data is out of range or invalid, the values are dashed, and the
wind arrow is removed.
4.4.6 Barometric Pressure Setting Display
The Barometric Pressure Setting Field is displayed on the upper right corner of the Data
Bar and is pilot-adjustable, as discussed in Section 4.4.1. When the Altitude Tape is
disabled, the Barometric Pressure Setting field remains visible. However, an installer can
disable the field and remove it from the display. .
