4.3.10.4 TERMINAL ANNUNCIATE*
When performing approach navigation, the TERMINAL ANNUNCIATE output is active when operating
within 30 nautical miles of the departure or arrival airport and the CDI scale is the equivalent or 1.0 nm or
less.
4.3.10.5 TAWS AUDIO ACTIVE OUT*
The TAWS AUDIO ACTIVE OUT is active when the GTN is playing a TAWS alert. This output can be
connected to the Audio Inhibit input of other units with audio that is lower priority than TAWS.
4.3.10.6 VLOC ANNUNCIATE* (GTN 750 Only)
The VLOC ANNUNCIATE output is driven when the unit is configured with a single CDI/HSI and the
VOR/ILS data is being displayed on the CDI/HSI. This output parallels the VLOC annunciator on the
display.
4.3.10.7 LOI ANNUNCIATE*
The LOI ANNUNCIATE output is active when the GPS receiver detects a position error, or is unable to
calculate the integrity of the position. On the 400W/500W Series navigators, this output was called
'Integrity Annunciate'.
4.3.10.8 MESSAGE ANNUNCIATE*
When a new status message is available, the MESSAGE ANNUNCIATE output is active and the
message annunciator flashes. When status messages remain effective, the message annunciator
illuminates continuously.
4.3.10.9 APPROACH ANNUNCIATE*
When performing approach navigation, the APPROACH ANNUNCIATE output is active while an
approach is active.
4.3.10.10 ILS/GPS APPROACH*
The ILS/GPS APPROACH output is active when:
GPS navigation is selected and either a GPS approach mode is active or 0.3 nm is selected for the
CDI full scale deflection; or
VLOC navigation is selected and an ILS channel has been selected.
This output may be connected to the ILS Engage input of an autopilot or flight director to provide higher
autopilot gain while the GTN is operating in the ILS or GPS Approach modes of operation.
4.3.10.11 TAWS INHIBIT ANNUNCIATE*
The TAWS INHIBIT ANNUNCIATE is active when TAWS is inhibited on the GTN.
4.3.10.12 TERRAIN WARNING ANNUNCIATE*
The TERRAIN WARNING ANNUNCIATE is active when a TAWS warning is active on the GTN.
4.3.10.13 TERRAIN NOT AVAILABLE ANNUNCIATE*
The TERRAIN NOT AVAILABLE ANNUNCIATE is active when TAWS on the GTN is enabled but
not available.
4.3.10.14 TERRAIN CAUTION ANNUNCIATE*
The TERRAIN CAUTION ANNUNCIATE is active when a TAWS caution is active on the GTN.
