Garmin GPSmap 496 False Terrain Alert
Nope. I'm not following the ILS using the 496. I'm following the glide slope
receiver and localizer. The 496 is sitting there as a toy, and complaining
that we're about to hit terrain. Even as a non-IFR certified device, Garmin
confirms that the unit should not do this. Nor does it do this at any other
airport, nor on the flip side runway. This may be a software bug or an error
in the terrain database.
Will continue to troubleshoot.
Thanks,
-Ron

Ron,
This is very disconcerting to the passengers, and
if I was really flying the approach in IMC, you can be assured that this
would be extremely disconcerting to me!
I wish you the best for resolving the problem, but as an aside, you're
putting way more trust in a non-certified handheld device than I ever
would. What you pay for is what you get. The ILS you're following down
there IS certified, as is your receiver. I don't think the 496 nor its
terrain database were ever designed to do close range avoidance. Trust it
when avoind terrain by miles, not tens of feet.
