The system information, procedures and guidelines
found in this presentation are for Reference Only.
The information & procedures in this presentation
have been taken from the FAA Approved Airplane
Flight Manual and Pilot’s Operating Handbook (POH).
The Information & Procedures in this presentation
DO NOT SUPERSEDE the Information & Procedures
in the POH. In the event of conflict, the POH shall
take precedence.
System Description
The SkyWatch model SKY497 is an airborne Traffic
Advisory System (TAS). SkyWatch monitors a radius of
approximately 11 nautical miles around the aircraft by
interrogating transponders in the monitored area and
determining if a collision threat exists.
To determine if a collision threat exists, SkyWatch
calculates the range, altitude, bearing, and closure rate
of all transponder equipped aircraft within the 11 nautical
mile range.
SkyWatch can track up to 30 aircraft, but displays only
10 of the most threatening intruders.
System Description
SkyWatch will issue a Traffic Advisory (TA) when it detects
an intruder aircraft within:
0.55 nautical mile horizontal distance
±800 ft relative altitude
Or detects an intruder aircraft that is on a course that
will intercept the SkyWatch airplane’s course
within 20 seconds (non-altitude reporting intruder aircraft)
Or 30 seconds (altitude reporting intruder aircraft)
System Description
Traffic Advisories are indicated on the Avidyne MFD and the
GNS 430 displays as well as an audio advisory:
“Traffic-12 O'clock High – 3 miles”
Warnings are announced in the headphones and over the
cabin speaker.
System Description
The SkyWatch System consists of a Transmitter
Receiver Computer (TRC) installed under the copilot’s
seat just forward of the spar tunnel and a directional
antenna installed on the airplane exterior above the
cabin.
The system also utilizes inputs from the altitude encoder,
the aircraft heading system (PFD’s Magnetometer), and
a speed switch plumbed into the pitot system.
Electrical power for system operation is 28 vdc supplied
through the 2.5-amp SKYWATCH Circuit Breaker on the
Avionics Non-Essential bus.
Initialization
Self-Test
Automatic at power up
Requires 25 seconds to complete
Error messages are displayed on MFD
NOTE
The SkyWatch system will annunciate the aural test pass
only if the self-test is initiated by the pilot
Initialization
Self-Test
In addition to the power-up self-test, an automatic selftest is performed several times each minute.
If the SkyWatch is in STBY or FAILED modes, an
operator initiated self-test may be performed using the
Avidyne MFD setup page as described below:
1. Select the MFD SETUP page.
2. Press the Traffic Self Test Button on the left hand
side of the MFD page.
3. About 10 seconds later there will be a aural
announcement.
Traffic Types
Traffic Alert (TA)
Intruder will be displayed as a TA for 8 seconds
after threat has passed as well as the audio of
traffic location relative to aircraft when traffic
conflict is issued.
WARNING
The SkyWatch system does not provide conflict
resolution (RA). Any maneuver to avoid traffic
must be made by visual contact or at the direction
of Air Traffic Control.
Traffic Types
Proximate Traffic
Traffic within 4 NM and within 1200 feet
Other Traffic
Within 11 NM and within 9900 feet
NOTE
GPS display allows a view out to 12 NM, however the
system is only capable of displaying traffic within 11
NM.

Operation
During the takeoff run, SkyWatch will automatically
switch to operational mode approximately 8 seconds
after 35 KIAS is achieved.
During the landing roll out, SkyWatch will
automatically switch back to STBY approximately 24
seconds after the airplane slows to 35 KIAS or
below.
Operation
When the SkyWatch issues a TA (Traffic Advisory), visually scan
outside for the intruder aircraft. Call ATC for Guidance. If you visually
acquire the intruder aircraft, use normal right-of-way procedures to
maintain separation.
SkyWatch is a Traffic Advisory System (TAS), it should not be
referred to as TCAS (Traffic Collision Alert System).
No Recommended avoidance maneuvers are provided nor
authorized as a direct result of a TAS intruder display or TAS Alert.
Do not maneuver solely on traffic information shown on the
display. Information shown on the display is provided as an aid
in visually acquiring traffic.
It is not a replacement for ATC and See & Avoid techniques.
Controlled via GPS 430 interface

SkyWatch can only detect aircraft that are equipped with
operating transponders.
Traffic information shown on the GARMIN 430 displays is provided
as an aid in visually acquiring traffic. Pilots must maneuver the
aircraft based only upon ATC guidance or positive visual acquisition
of conflicting traffic.
If the pilot is advised by ATC to disable transponder altitude
reporting, the SkyWatch must be turned OFF.
