VASI, AVASI, etc, maybe a stupid question, but...
Hi everyone,
Maybe it's a stupid question, so in advance sorry about that.
I know what is a VASI and an AVASI, but what is exactly a SAVASI (Simplified Abbreviated Visual Approach Slope Indicator) ? What does 'Simplified' mean and how does it work ?
Thank for your answer(s).
Vincent.

which is the difference between a 3 degree PAPI and a 3 degree VASI??
VASIs are separate bars of lights (like multiple PAPIs) but each bar is always all red or all white. Glideslope info comes from the progressive change of colour of the bars. I'll try to find some pictures.
Ahh! Found some of PAPIs
And some VASIs.
