Gnd Glideslope Inhibit Discrete; Glideslope Inhibit Discrete; Gnd Glideslope Cancel Discrete; Decision Height Discrete - Honeywell MK V Line Maintenance Manual

3.8.12 GND GLIDESLOPE INHIBIT DISCRETE

Type: Switch for inhibit of Glideslope mode
Signal Status: Glideslope Inhibit or Not Inhibit
Fault monitoring: Mode 5 will be disabled and "Glideslope" will not be enunciated during cockpit Self-Test and the
long vocabulary test if inhibited.

Glideslope Inhibit Discrete

3.8.13 +28 V GLIDESLOPE INHIBIT DISCRETE
Type: Switch for inhibit of Glideslope mode
Signal Status: Glideslope Inhibit or Not Inhibit
Fault monitoring: Mode 5 will be disabled and "Glideslope" will not be enunciated during cockpit Self-Test and the
long vocabulary test if inhibited.
+28V Glideslope Inhibit Discrete

3.8.14 GND GLIDESLOPE CANCEL DISCRETE

Type: Supplied by momentarily actuated cockpit Glideslope mode manual inhibit switch.
Signal Status: Glideslope is canceled if glideslope function is active
Fault monitoring: Activation of this input for more than 15 seconds will result in the 'Glideslope Cancel Invalid' fault
which will cause a GPWS INOP indication. Typically, the Glideslope cancel can only be selected
below 2000 feet AGL. However, some configurations only allow it below 1000 feet AGL.
Glideslope Cancel Discrete

3.8.15 DECISION HEIGHT DISCRETE

Type: Decision Height Bug switch
Signal Status: Less than Decision Height or Greater than Decision Height
