1.2.9 ADS-B Traffic Advisory System Overview (optional)
Release 2.0 and later. The ADS-B Traffic Advisory System (ATAS) [previously referred to as TSAA]
function provides traffic advisories using ADS-B In information via aural announcements over the
cockpit speakers or headset and visually via the display or a cockpit lamp. ATAS and TAS/TCAS may
operate at the same time with traffic information being correlated by the unit.
• The system display shows the relative position of traffic using text, shapes and colors.
• The dimensions of Collision Airspace Zone (CAZ) are 500 ft. horizontal radius and +/- 200 relative
altitude.
• The dimension of the Protected Airspace Zone (PAZ) is dependent on closure rate. The PAZ
dimension decreases as closure rate decreases with a minimum 500 ft. horizontal radius and +/- 300
ft. (Sensitivity A) or +/- 500 ft. (Sensitivity B) relative altitude.
• The effective active-mode surveillance range is 40 nmi and track 60 ATCRBS intruders
simultaneously with the target bearing relative to the nose of own aircraft.
• The tracking of targets is in a cylindrical volume centered on own aircraft that has, at a maximum, a
radius of 20 nmi and extends 10,000 ft. above and 10,000 ft. below own aircraft.
1.2.10 Traffic Alert and Collision Avoidance System (option) Overview
Release 3.0 and later. The Traffic Alert and Collision Avoidance System (TCAS I) option 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. 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 unit 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 unit or alternate display.
• The system display shows the relative position of traffic using text, shapes and colors.
• The effective active-mode surveillance range is 35 nmi and track 35 ATCRBS intruders
simultaneously with the target bearing relative to the nose of own aircraft.
• The tracking of targets is in a cylindrical volume centered on own aircraft that has, at a maximum, a
radius of 35 nmi and extends 10,000 ft. above and 10,000 ft. below own aircraft.
1.2.11 Terrain Awareness and Warning System Overview (optional)
Release 2.0 and later. The Class B Terrain Awareness and Warning System (TAWS) function
continuously monitors the aircraft’s position, altitude, speed, track, and phase of flight and compares the
information to an internal terrain, obstacle, and runway database. If TAWS predicts a potential Controlled
Flight Into Terrain (CFIT) situation, the system alerts the pilot visually on the Lynx NGT-9000 display,
aural announcements over the cockpit speakers or headset, or via cockpit lamps (caution and warning).
• The Remote Mount NGT-9000R does not have a TAWS display available (audio and lamps only).
1.2.12 TerrainVision
TM
Release 2.1 and later. This optional function provides a terrain display (“TERR Advisory”) similar to the
TAWS display but without visual or audio alerts.
• This function is not available for the Remote Mount NGT-9000R.
• TerrainVision
TM
is not considered a Class B TAWS.
