TRAFFIC ALERT AND COLLISION AVOIDANCE
SYSTEM (TCAS)
ThisTCASIIsystemisdescribedinHoneywellPub. No. 28--1146--070,
and includes the following elements:
D Computer
D Antenna.
TCASisdesignedtoactasabackuptotheATCand the”seeandavoid”
concepts. TCAS continuously surveys the airspace around theaircraft
seeking ATC transponder replies from other aircraft in the vicinity.
Flightpaths of these aircraft are predicted based on their tracks. When
TCAS is activated through the radio management unit and selectedfor
display on the MFD, nearby traffic is displayed. When traffic poses a
collision threat, the PFD displays a climb or descent vertical speed
command.

880 Weather Radar System, which is fully described in
Honeywell Pub. No. A28--1146--102, includes the following components:
D Weather Radar Receiver Transmitter Antenna
D Weather Radar Controller.
The PRIMUS
â
880 Weather Radar System is an X--band radar
designed for weather detection and analysis. The PFDand MFD show
storm intensity levels in bright colors contrasted against a deep black
background. Areas of heaviest rainfall appear in magenta, significant
rainfallisinred,rainfallofmediumintensityappearsinyellow,andareas
ofweakestrainfallappearingreen.Afterproperevaluation,thepilotcan
chart a course around these storm areas. The radar can also be used
for ground mapping. In the map mode, prominent landmarks are
displayed that help the pilot identify coastline, hilly or mountainous
regions, cities, or even large structures. In ground mapping mode,
video levels of increasing reflectivity are displayed as black, cyan,
yellow, and magenta. The weather radar system has a turbulence
(TURB) detection mode and an autotilt function.
