SkyView Pilot’s User Guide - Revision S 7-29
Traffic is displayed using a set of symbols that are commonly used in aviation for traffic/TCAS
systems. As seen in Figure 100, this includes:

A symbol that depicts the type of traffic. It can be a Traffic Advisory Symbol, Proximity
Advisory Symbol, or Non-Threat Symbol. These are further discussed later in this
section. Data being received by a TIS device, such as the SV-XPNDR-26X, is limited to 8
simultaneous targets by the inherent capability of the TIS system. If there are more than
8 traffic targets that are potential threats, the TIS ground station determines the highest
priority targets and transmits them to your aircraft.

Relative altitude in hundreds of feet is displayed above the symbol as a signed integer.
So, the target in Figure 100 is +08, or 800 feet higher than our aircraft. This area is blank
if the altitude of a target is not known.

An up or down arrow to the right of the traffic symbol indicating whether the aircraft is
climbing or descending, if available from the traffic source. No arrow is shown when an
aircraft is maintaining altitude, or if climb/descend information is not available. Traffic
from TIS traffic sources such as the SV-XPNDR-26X will not show a vertical speed
component unless it is greater than +/-500 fpm

If available from the traffic device, an orange vector arrow that starts at the target and
points in the aircraft’s direction of travel. This length of the vector represents where the
aircraft is expected to be in one minute based on its current trajectory.
o The data received by a TIS device (such as the SV-XPNDR-26X) does not include
the speed of aircraft since it is not sent by the ground-based TIS equipment.
SkyView therefore assumes that all TIS targets are travelling at 150 knots.
o TIS additionally only provides the direction that individual traffic targets are
moving in to the nearest 45° increment (0 °, 45°, 90°, etc.). This limitation may be
noticed as a seemingly abrupt change in aircraft direction on the display as the
traffic direction “snaps” from one 45° increment to the next when the TIS device
updates an aircraft’s direction.
Traffic displayed on the Map Page can be configured to include just Traffic
Advisories (TA), all targets, or no targets. See the SkyView System Installation Guide
for information on how to configure how traffic is displayed.
Traffic Advisory (TA) Targets

These are targets that have a high chance of ending up near the aircraft. They will often be
lower priority targets that then become higher priority targets as they approach. SkyView
