Eyes That Never Blink™

Early Traffic Alert/Advisory Systems

In the early days of flight, pilots were equipped with all they needed for effective collision avoidance–a sharp pair of eyes.

PreliminaryBut increasing traffic at higher speeds led to the development of TCAS I and II (Traffic Alert and Collision Avoidance Systems)

which were too expensive for most regional airlines, business aircraft, and general aviation aircraft.

SKYWATCH®

BFGoodrich Avionics Systems, Inc. recognized the need for an alternative to expensive TCAS systems and developed the SKYWATCH model SKY497 Traffic Advisory System (TAS) and the SKYWATCH HP model SKY899 TAS/TCAS I.

The SKYWATCH HP can be installed as a TAS to provide most of the capabilities of TCAS I, but at a significantly lower cost, making it practical for small aircraft. The SKYWATCH HP can also be installed as a TCAS I.

In addition to its TCAS I capability, SKYWATCH HP improves upon the SKY497 by adding ADS-B surveillance, a larger display range (15 nmi), and a higher maximum closure rate (1200 kn).

Proven Experience

BFGoodrich Avionics Systems, Inc. has been involved in the development of collision warning programs since the early 1980’s. In 1985, BFG began development of an enhanced collision warning system for the Navy’s T-34C training aircraft.

Based largely on the success of the Navy project, BFG was selected to validate the specifications for TCAS I. As a result, BFG’s original TCAS I unit, the TCAS791 was the first TCAS I to be TSO’d, first to receive a full, unrestricted STC, first to fly, and first to be delivered.

Safety Summary

	CAUTION	To avoid power surges that could damage the SKY899 and the
	page 3-1	optional WX-1000, start your engines before turning on the SKY899.
		If the SKY899 is in SKYWATCH mode, the display will not auto-
	page 3-5	matically switch into Stormscope mode to display thunderstorms or
		Stormscope errors. Use the remote SKYWATCH/Stormscope mode
		switch to periodically check for thunderstorms or Stormscope errors.
		The SKY899 relies on information obtained from transponders in
	page 3-6	nearby aircraft. The SKY899 does not detect or track aircraft which
		are not equipped with an operating Air Traffic Control Radar
		Beacon System (ATCRBS) transponder.
		The SKY899 does not track intruder aircraft approaching at a
	page 3-6	closure rate greater than 1200 knots.
		Some traffic within the chosen display range may not be displayed
	page 3-6	due to traffic prioritizing, antenna shielding, or ground intruder
		filtering.
	CAUTION	Optimum SKY899 performance is realized when intruder aircraft
		are reporting their altitude (via a mode C or other altitude
	page 3-6
		reporting transponder).
		Do not attempt evasive maneuvers based solely on traffic informa-
	page 3-6	tion on the display. Information on the display is provided to the
	Preliminary

flight crew as an aid in visually acquiring traffic; it is not a replacement for Air Traffic Control (ATC) and See & Avoid techniques.
