Description
Traffic Awareness System (TAS)
The TAS option is available with model NGT-9000+ and NGT-
9000R+. TAS is an active system that operates as an aircraft-to-
aircraft interrogation device. The unit interrogates transponders in the
surrounding airspace similar to ground based radar; with an effective
active-mode surveillance range of 35 nmi. When replies to these
active interrogations are received, the responding aircraft’s range,
altitude, and closure rates are computed to plot traffic location and
predict collision threats. The NGT-9000+ or NGT-9000R+ 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 NGT-9000+ or alternate display.
The system display shows the relative position of traffic using text,
shapes (i.e., Traffic Advisory = solid circle; Other Traffic = open
diamond, Proximate Traffic = solid diamond) and colors.
The effective active-mode surveillance range is 35 nmi and
track 35 ATCRBS intruders simultaneously with the other aircraft
bearing relative to the nose of own aircraft.
The tracking of other aircraft is in a cylindrical volume centered
on own aircraft with a maximum radius of 35 nmi and extending
10,000 ft above and 10,000 ft below own aircraft.
The system uses an audio output that announces Traffic Advisory
and relative bearing, relative altitude and range.
Refer to Chapter 4 Principles of TAS Operation for more information.
