Dear friends,
Some days ago I bought a GTN 750 and GTN 650. The problem is now, that the ILS-approach does not work any more. I put both CDIs into the VLOC-mode, the device accepts the localizer, but it don't come down on the glidepath although the autopilot is in the approach mode. It is not so, that is doesn't work properly (like a wrong glide-path-angel) it doesn't work anyhow.
