Target Alt - can’t set AGL?

[Crimguy]

I recall being able to set a target altitude prior to arriving at a waypoint in AGL on the real GTN but that button is always greyed out. Somethjng I’m doing wrong or a limitation in the simulator?

Hello,

As the TDS GTNXi is based on the real world unit, operation is exactly the same as in real life. Most likely this is a confusion. Please provide us with a screenshot of what you are seeing and let us know how to reproduce/as well as what you expect to happen differently.

Best regards.
