Vertical Situation Display in B737 GC
Some time ago there has been a thread here in the forum that was started by Ray Proudfout about the VSD.
I played around a bit with it and it worked as long as you are in an area that is covered by a terrain texture file. When you'r outside of the coverage of such a file the VSD still works but there is nothing to see.
Unfortunatley the only way to switch the VSD ON or OFF is through the CDU (go to index/maint/efis/terrain). But maybe Ray has found a method of performing this through another method. I have some switches left on a Go-Flight toggle panel that could be used for this purpose, Ray could you share your fiindings with us?
Furthermore I looked-up this VSD on the internet and found quite some information about it. When you compare the VSD as installed in the PM SW with the real thing you have to conclude that it's nice but just not complete.
I'm sometimes wondering why PM doesn't document the features of the SW, looks like a kind of eastern egg now.
