Textual info items that provide additional data about the HSI source are displayed to the left of
the HSI display. The information available depends on the data being provided by the HSI
source. Examples of info items that may be displayed include DTW (distance to waypoint), ID
(VOR identifier), and frequency.
Wind Vector
Wind vector information is located just above the OAT display on the PFD. The
winds aloft arrow indicates the wind direction relative to your current direction of
flight. The wind strength, direction, and cross wind component are also textually
provided. If SkyView cannot make an accurate winds aloft calculation, the
arrow is not displayed and the numbers are replaced by dashes. The display of
winds aloft requires an active GPS connection and an OAT probe. In very light
winds, the wind speed number is not displayed, although the arrow is. Note
that due to a limitation in the SV-GPS-250 hardware, winds information will
not be available above 415 knots ground speed if it is being used as the GPS source.
Slip/Skid Ball
The action of the slip/skid ball simulates an analog slip/skid ball and provides a
visual representation of lateral acceleration. When the ball is within the two
vertical lines, the aircraft is in coordinated flight. Figure 28 is an example
SkyView slip/skid ball.
Angle of Attack Indicator
The Angle Of Attack (AOA) Indicator will display only when a Dynon AOA/Pitot probe
has been properly installed and calibrated. During normal flight, the AOA Indicator
will display green. As the AOA approaches and then reaches critical, the green and
yellow bars will disappear, leaving only red. Figure 29 is an example SkyView AOA
indicator.
A thorough explanation of AOA and the principles of operation of Dynon's AOA
Pitot probe are beyond the scope of this guide. Detailed information about AOA
and Dynon's approach to AOA is available at
