Subject: Oops, I originally had ramped the vasi/papi color transition the wrong way.
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=65a49bb6e4bc6cbd14feb065f55b798b4c1db362;p=simgear.git

Oops, I originally had ramped the vasi/papi color transition the wrong way.
So as you passed through the target glide slope from low to high it would
be colored: red -> white -> small range of transition to red -> white.
Now it goes the right way so you get: red -> smooth transition to -> white.
You can tell you are getting high if you see the bottom vasi start to turn
pink ... etc. etc. hopefully just like in real life.
