EYES THAT NEVER BLINK™ Early Traffic Advisory Systems In the early days of flight, when air traffic was light and slower moving, pilots were equipped with all they needed for effective collision avoidance–a sharp pair of eyes to scan the horizon. Even today, visual contact is still the surest means of identifying intruder aircraft. But with more traffic in closer proximity and at higher speeds, today’s pilots need all the help they can get.

System Description SKY497 Chapter 1 System Description General Description The SKYWATCH™ model SKY497 from BFGoodrich Avionics Systems, Inc. is an airborne Traffic Advisory System (TAS). It monitors the airspace around your aircraft and advises the flight crew where to look for transponder-equipped aircraft that may pose a collision threat. The SKY497 is intended for use by corporate and general aviation aircraft. Figure 1-1 shows the major components of the SKY497.
System Description SKY497 Display The display is a self-contained, 3-ATI-sized unit with a high resolution, green monochrome Cathode Ray Tube (CRT) display. The bezel contains four momentary contact push-button switches and an on/off/brightness knob. The display provides control and display functions for the SKY497 and for a WX-1000 STORMSCOPE (if installed). The display does not display traffic and storm information simultaneously.

System Description SKY497 Functional Description The SKY497 is an active system that operates as an aircraft-to-aircraft interrogation device. The SKY497 interrogates transponders in the surrounding airspace similar to the way that ground-based radar interrogates aircraft transponders. When the SKY497 receives replies to its interrogations, it computes the responding aircraft’s range, bearing, relative altitude, and closure rate. The SKY497 then plots the traffic location and predicts collision threats.
