GPWS -SELF TEST -LEVELS 2-5
General Description
The ground proximity warning computer (GPWC) has six levels of self test:
*
1 -GO/NO-GO operational test
*
2 -Current faults
*
3 -System configuration
*
4 -Fault history
*
5 -Alert/warning history
*
6 -Discrete input test.
Self test levels 2-6 access self test information not available through the maintenance access terminal (MAT). Use a 600 ohm headphone to listen to the test information. Plug the headphone into the jack on the front panel of the GPWC.
Use the self test button on the front panel of the GPWC to access levels 2-6. The self test button has these two modes:
*
Short cancel -push the button for less than two seconds
*
Long cancel -push the button for more than two seconds.
Use the self test button for these functions:
*
Start self test level one
*
Go to the next item or flight leg within a test
*
Go to the next self test level
*
End the self test.
EFFECTIVITY
BEJ ALL
When a test level ends, the aural message PRESS TO CONTINUE annunciates. Push the self test button to go to the next test level. If you do not push the self test button within three seconds, self test ends.
Level Two Self Test -Current Faults
A level two test begins with the aural message CURRENT FAULTS. If there are no current faults, you hear the aural message NO FAULTS. If faults exist, the GPWC annunciates the faults one at a time. A short or long cancel ends the level two test.
Level Three Self Test -System Configuration
A level three test annunciates the GPWS configuration. A level three test begins with the aural message SYSTEM CONFIGURATION. A short cancel causes the test to go immediately to the next configuration item. A long cancel ends the level three test. A level three test provides this information:
*
GPWC part number
*
GPWC modification status
*
GPWC serial number
*
Application software version
*
Configuration software version
*
Terrain database version
*
Envelope modulation database version
