Probable Cause: 

The “Audio Inhibit” or both “GPWS Inhibit” and “Terrain Inhibit” discrete inputs are true. 

Action: 

Deselect or remove these inputs. 

Enunciation: 

“GPWS INHIBITED” 

Probable Cause: 

The “GPWS Inhibit” discrete input is true (selected) and “Terrain Inhibit” is not.

The Short Level 1 Self-Test is intended to provide a Go/No Go confidence test to indicate EGPWS functionality.  It 
indicates which Modes of the EGPWC are currently not available and activates system outputs.  The short Level 1 
Self-Test is a subset of the Long Level 1 Self-Test. 

Upon successful completion of the preamble the short Self-Test is started.  A Short Level 1 Self-Test sequence 
(following the Preamble) is as follows: 

•  GPWS INOP, Windshear INOP, Terrain INOP (or Terrain Not Available) lights turn on *
