Pre-Flight
The 430 on our newly acquired Grumman Tiger seems to be loosing GPS signal, especially during the approach phase. It acquires satellites quickly during the start up and generally holds fine. At times, it looses signal during the cruise momentarily. During the approach phase, it failed RAIM, and messages kept popping indicating no coverage, loss of signal, etc.
The plane currently at the avionics shop. The mechanic ran several tests on ground, and could not replicate the problem. The thinks that the antenna cable might be a culprit, but he didn't sound so sure. I was wondering if any of you have had a similar issue and how it was resolved. Thanks for your inputs in advance.
