INTRODUCTION

The Traffic Function of the Bendix/King KMD 550/850 Multi Function
Display allows for the display and control of several models of traffic
avoidance systems. Some examples are TCAS I (Traffic Collision
Avoidance System), TCAS II, TAS (Traffic Avoidance System) and TIS
(Traffic Information Service).
This Pilot's Guide Addendum describes the operation of the KMD
550/850 display for controlling the display of traffic. The detailed descrip-
tion of the general operation of the KMD 550/850 is contained in the
other sections of the KMD 550/850 Pilot's Guide. For detailed informa-
tion on the proper use and interpretation of the displayed traffic data
when using TCAS I, TCAS II and TAS systems, please reference the
pilot's guide that is provided with the traffic avoidance system.
The traffic avoidance system is used for detecting and tracking aircraft
near your own aircraft. Aircraft detected, tracked, and displayed are
referred to as Intruders. Intruders are shown as symbols on the traffic
display. The system identifies the relative threat of each Intruder by
using various symbols and colors. The intruder's altitude, relative to
your own aircraft's altitude, is annunciated if the Intruder is reporting alti-
tude. A trend arrow is used to indicate if the Intruder is climbing or
descending more than 500 feet per minute.
The Traffic Information Service (TIS) is a data link service that provides
information similar to VFR radar traffic advisories normally received over
voice radio. The data is received from the terminal Mode S radar system
through a TIS capable Mode S transponder to the KMD display once per
radar scan (approximately every 5 seconds).
TIS provides the relative position, relative altitude, altitude trend, and
estimated ground track angle for as many as 8 intruders that are within 7
NM horizontally and +3,500/-3000 feet vertically of the aircraft receiving
TIS. Only aircraft with operating transponders that are within the surveil-
lance volume of a TIS Mode S radar are visible to TIS. Terminal Mode
S radars equipped with TIS provide the service to 55 NM (or possibly
greater) of the radar location, and as low as the "line of site" limitation
inherent to radar surveillance.
ATC procedures and the "see and avoid concept" will continue to be the
primary means of ensuring aircraft separation. However, if communica-
tion is lost with ATC, TCAS/TAS/TIS adds a significant backup for colli-
sion avoidance.
