PFD Operation
SkyView SE Pilot’s User Guide - Revision I 4-11
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 SE 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 and SV-GPS-2020 hardware, winds information will not be
available above 415 knots ground speed if it is being used as the GPS source. The
Wind Vector will not appear if the SV-ADAHRS-200/201, SV-MAG-236, GPS, or OAT is not
functional.
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 21 is an example SkyView SE 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 22 is an example SkyView SE 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 dynon.com/aoa.
OAT
Outside air temperature (OAT) as shown in Figure 23 is displayed in the very
lower-right corner of the PFD. Units can be set to degrees Fahrenheit or degrees
Celsius. Reference the SkyView Classic / SE / HDX System Installation Guide for
instructions on how to change the displayed units. If OAT is not valid (i.e.,
disconnected or damaged), then "OAT ---" is displayed.
Extreme Pitch Warning Indicators
The SkyView SE PFD shows large red arrows as pitch warning indicators in extreme attitudes
(i.e., 45 degrees or greater pitch up or down). These indicators point to the horizon and indicate
which way to maneuver to attain a level attitude. Indicators are accompanied with a small sliver
of sky or ground bordered with a white dashed horizon line, depending on the current attitude.
The pitch warning indicators can be enabled or disabled through the setup menus. See the
