TAWS failure

[davenicoll]

Hello,

After starting up my GTN units I get a TAWS failure followed by the following message:-

" Terrain/TAWS configuration is invalid. GTN needs service"

Can someone explain please and how to cure it.

Thank you

Hello,

While in flight, from within the TDS GTNXI Interface, Settings tab, check each GTNXo units settings for the TAWS Mode to be set to auto, then restart the flight.
