1.2 FUNCTIONAL DESCRIPTION
The SKYWATCH® HP SKY899 is a new generation airborne traffic alert/advisory system that increases
the active-mode surveillance range over the SKY497 system from 11 nmi to 35 nmi.
The SKY899 advises the flight crew where to look for transponder equipped aircraft that may pose a
collision threat. It is intended for use by corporate and general aviation aircraft. SKY899 alerts the flight
crew to nearby transponder equipped aircraft and assists the pilot in the visual acquisition of aircraft that
may represent a danger. Traffic information, out to a selected range, is graphically displayed on the
display. The system display shows the relative position of traffic using text, shapes (i.e., Traffic Advisory
= solid circle; Other Traffic = open diamond) and colors (if display is TCAS I compatible). Major
differences between SKYWATCH and SKYWATCH HP are listed below:
