4-4 SkyView Pilot’s User Guide - Revision Q
Airspeed Indicator
The Airspeed Indicator is displayed on the left side of
the PFD and incorporates an airspeed tape with a
digital readout, true airspeed (TAS), airspeed trend
indicator, and airspeed bug. Figure 14 is an example
SkyView Airspeed Indicator.
Units can be set to miles per hour, nautical miles per
hour (knots), or kilometers per hour. Reference the
SkyView System Installation Guide for instructions on
how to change the displayed units.
The airspeed tape displays indicated airspeed
including gray, white, green, yellow, and red ranges
to provide a graphical representation of aircraft
speed in relation to the aircraft's limits. These ranges
are controlled by setting the airspeed limitations for
the aircraft. Refer to the SkyView System Installation
Guide for instructions on how to configure the
airspeed limitation color thresholds.
Airspeed will display “---” at zero through 20 knots, at
which point it will become alive. Once alive, it will read
down to 15 knots. Below 15 knots, “---” will again be displayed.
The indicated airspeed (IAS) digits scroll up and down, simulating an analog Airspeed Indicator.
The rate of change of the digits provides a sense of the increase or decrease in speed.
The airspeed trend indicator (ATI) is displayed as a magenta bar on the airspeed tape. It grows
proportionally in the direction of the rate of change (acceleration or deceleration). The ATI is
scaled to indicate a 6-second airspeed trend which means that if the acceleration is kept
constant, the airspeed will end up at the number indicated at the end of the trend line after 6
seconds have passed.
True airspeed (TAS) is digitally displayed at the bottom of the airspeed tape.
Airspeed Bug
The airspeed bug is displayed in cyan on the airspeed tape and its associated digital readout is
displayed at the top of the Airspeed Indicator.
To set the airspeed bug:
1. Enter the Joystick Function Menu.
2. Move the joystick up or down to highlight (IAS).
3. Click the joystick or move it left or right to close the menu (this is optional).
(IAS) will now display just above that joystick. The airspeed bug setting on the PFD will be
outlined to signal that it is selected. Turn the joystick to adjust the airspeed bug. Note that
while the airspeed bug is changing, its display window lights up in cyan to draw your attention
