Garmin GTN 750 Touch X-plane

Recommended Posts

XP reallity GTN 750/650 manual shows about Failue Annuciation function.

Anybody how knows how such function could be impemented in X-plane?

The only working is as shown i first row. 

Tested in XP-11 and XP-9, same same


Failures Annunciation


When enabled in the configuration panel, the GTN plugin uses the following datarefs6 as failures sources:

sim/operation/failures/rel_gps sim/operation/failures/rel_g430_gps1

Satellite reception failure, displays "No GPS Position"


Differential GPS failure, reduces location accuracy.
Satellite reception mode switches to 3D instead of 3D-Diff.


COM radios failure only.


NAV radios failure only.


Both COM and NAV radios failure.


Transponder failure.


Audio Panel failure.

If data fields become invalid, the GTN typically annunciates the failures with a large red X, as shown.

The only failure that works is GPS unavailable via GPS430 command in the first line above.

I cannot figure out how to reach this functions!

I whant to control the operation failure from IOS if possible or thru keyboard. 

Even in plugin admin there is som keys to use but those above is not vissible anywhere.

Tested in XP 9 and XP 11 and that is the same.

Best regards
