Section 7 - Systems Description
The SkyWatch model SKY497 is an airborne Traffic Advisory System
(TAS). SkyWatch monitors a radius of approximately 6 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 with the 6 nautical
mile range. When SkyWatch detects an intruder aircraft within 0.55
nautical mile horizontal distance and a ±800 ft relative altitude or
detects an intruder aircraft 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),
SkyWatch will issue a Traffic Advisory (TA). Traffic Advisories are
indicated on the GNS 430 displays and aural “Traffic, Traffic” warnings
are announced in the headphones and cabin speaker.
