Section 1 Description

1.1 Introduction

This manual contains information on the RGT Series Switch/Annunciator Panel. All
derivative products will be covered by manual supplements, which can be obtained from
NAT as required.

Information in this section consists of purpose of equipment, features and specifications.

1.2 Purpose of Equipment

The RGT-102 is an advanced control panel for Enhanced Ground Proximity Warning
Systems (EGPWS). The design incorporates user-friendly controls, multiple mounting
options, panel lighting, and dual control installation capability.

Dual Control Installations

Providing the ability to have dual controls in the cockpit is an industry exclusive for the
RGT-102. Aircraft installations are no longer restricted to limited panel locations. The
controller can be mounted as either a single unit between both pilots or as two individual
controls on either side. This provides more flexibility in mounting options and ensures
easy accessibility for both pilots.

Controls

Each control panel provides DISPLAY and SYSTEM illuminated annunciator switches.
The DISPLAY switch provides fast selection of enabling and disabling of the terrain
(TERR) mode of the EGPWS system. The SYSTEM switch for all variants allows the
override function of the system to be selected or deselected; this is indicated by the
condition of the OVRD light of the upper half of the SYSTEM switch. Depending on the
variant, the lower half of the SYSTEM switch provides status indication for FAULT,
INOP or FAIL conditions of the EGPWS system. A protective clear cover over the
SYSTEM switch prevents accidental activation.

Multiple Mounting Options

The RGT-102 is available in a 1.5" x 3.5" instrument panel CAM mount or 5.75" Dzus
mount configuration for pedestal installations. An adapter plate (p/n 910-1410-215) is
available to convert the instrument panel cam mount version to a Dzus mount, providing
additional installation flexibility.

Panel Options

Panel lighting is standard white, 0-28 Vdc, or 0-5 Vac. Switch indicator displays can be
driven directly by the aircraft 14/28 Vdc display bus or internally from a brightness bus
that is controlled by the aircraft instrument panel power bus. Panel colours are black,
grey, or brown.
