5 AIRCRAFT APPLICATION DATA
This section describes the MK VI and MK VIII EGPWS interfaces for aircraft applications. Section 5.1 is a listing of the
selection categories defining the various aircraft sensor interfaces and EGPWS functional options. Section 5.2 describes
how the Category ID’s are selected and programmed for the interface to aircraft sensors and EGPWS functional options.
Section 5.3 and its sub-sections define the specific aircraft interfaces available for the MK VI and MK VIII EGPWS.
5.1 Configuration Types
The selection of the basic interfaces to the MK VI and MK VIII EGPWS can be found in the following categories:
Aircraft / Mode Type Select Category 1
Air Data Input Select Category 2
Position Input Select Category 3
Altitude Callouts Category 4
Audio Menu Select Category 5
Terrain Display Select Category 6
Options Select Group 1 Category 7
Radio Altitude Input Select Category 8
Navigation Input Select Category 9
Attitude Input Select Category 10
Heading Input Select Category 11
Windshear Input Select Category 12
I / O Discretes Select Category 13
Audio Output Level Category 14
Future Configuration Category Category 15
Future Configuration Category Category 16
Future Configuration Category Category 17
5.2 Configuration Selection
Each category provides information relative to aircraft interfaces or EGPWS functional options required or used for
EGPWS operation. Each category must be defined for the specific aircraft application according to the available aircraft
sensors or equipment and the intended EGPWS function. The choices provided are available in each category identified
by an “ID” number. The ID number is selected for each category and is used to load the selected configuration in a
configuration module installed in the aircraft wiring (physically part of one of the EGPWC mating connectors). For
example, selecting Category 2, ID 1 defines the Air Data Input as ARINC 429 per Table 5.3.2-1 in Category 2. With this
ID programmed into the configuration module the EGPWC will look for and use the interface defined for this ID. Table
5.2 can be used to record the selected ID for each category for later reference when programming the configuration
module. This programming is accomplished using a programming software tool available from Honeywell or generating a
data text string and transferring this data (in either case) via the EGPWC RS-232C (see 4.3.1) to the configuration module.
Once programmed, the configuration is available and read by any installed EGPWC on power up.
