Mark --

What Lou just posted is all there is, I guess. I can see some practical application for the Radar Altimeter within a couple thousand feet AGL, but the other one doesn't seem very useful. The one in the 727 was a major leap forward!

I have tried both of the forum methods of posting pics and I always get a message that for security reasons I have to re-select the pic. When I do re-select it. I get this symbol, but no picture is uploaded.

Lou, thanks for the explanation and the tips for paint.net etc. Will look into that.
