3.3 Configurable Interface s
The following subsections define configurable interfaces for the EGPWS. Typical interface
connection information and diagrams are provided. Use this in conjunction with Appendix E
which has detailed interface configuration information.
3.3.1 Category 1 - Aircraft / Mode Type Select
Category 1 specifies the general aircraft type, warning mode definitions, , fixed or retractable
gear, and engine torque interface.
Note: Category 15 will set the engine torque value used for autorotation mode.
3.3.1.1 Aircraft / Mode Type
The Aircraft Type identifies the aircraft as “Manufacture and Model”. The aircraft category defines
configurable data that control performance. The configurable values are not user defined or
controlled.
Appendix E Table E 3.1.1
lists the combinations of Aircraft/Mode Types and identifies the first MK
XXII EGPWS version in which the option was available (see the Effectivity entry), and describes
the options available with each Aircraft/Model type (see Description column).
3.3.1.2 Instructions
1. Using Appendix E Tables E 3, under Step/category 1 select Aircraft type. Using Table E 3.1.1
select ID number for your aircraft type and record that number on Table E 3 under Ident No.
This number will be used for programming the configuration module.
2. Using Appendix E Table E 3.1.1 under Aircraft/Model Type Table use table E 3.1.1-x to
determine the torque wiring interconnects and record it on Appendix A Fig A1-2.
Note. Aircraft types 129, 130 and 138 with software version –010 and earlier are configured for
the raw low level DC torque input. This interface will not work. With software version –011 these
types are configured to use an external Buffer Amplifier provideing a gain of 30.23. For these
applications it is recommended that either the No Torque configuration or the Shadin Converter
configuration, described below, be used.
3.3.1.3 Generic Helicopter with and without Torque
For any airframe not listed in Appendix E table E 3.1.1 contact Honeywell GPWS hot line 1
800 813-2099.
Generic helicopter types are provided for aircraft with torque interfacing problems. Category 1 ID
type 146, 147, 148, and 149, allow interface to airframes without torque input,. These types do
