CHAPTER 1. WELCOME TO THE ST3400 TAWS/RMI
What is the ST3400
The ST3400 is a multi-function display with a self-contained TAWS
(Terrain Awareness Warning System) system. It includes a TAWS
computer, graphics symbol generator and an integrated full-color screen,
built within a standard 3-inch instrument chassis. It includes bearing-
pointer features to directly replace an existing mechanical RMI (Radio
Magnetic Indicator), and has the optional capability of acting as a Primary
or secondary Traffic indicator, showing traffic either in standard TCAS
format or overlaid on terrain when connected to an external traffic
detection system.
Terrain protection is enabled during all airborne phases of flight -
Departure, Enroute, Terminal, and Approach and in any selected display
mode.
The ST3400 is a situational awareness tool and an alerting and warning
device. It is not intended to be used for primary navigation of the aircraft.
During normal flight operations the system remains essentially silent. It
uses GPS, radar altitude, barometric altitude, and other relevant data in
combination with its internal database information to provide the pilot with
a full-time terrain display. The look ahead function compares the aircraft
flight path to terrain and obstacle database information and distance to
known runways.

are smart and exclusive Sandel features that
provide the pilot with fast access to usable information, maximizing
relevant data and reducing nuisance alerts. Pilot workload in interacting
with the system during normal flight is minimal. In PRED (Predictive)
mode, the ST3400 can show only terrain that represents a potential threat
during an emergency climb in an easily interpreted format.
The ST3400 includes a built-in caution and warning system providing
annunciation and aural alerts. Provision is made for all the
traditional/standard Ground Proximity Warning System (GPWS) alerts,
new enhanced terrain alerts, and various advisories. All of the alerts are
automatically displayed. The unit supports optional external caution and
warning annunciators.
An internal recorder automatically records a minimum of the last ten hours
of flight data. Oldest data is automatically overwritten with most recent
data. This data can be used by Sandel Customer Support to analyze recent
alert activity.
