Pulsating Visual Approach Slope Indicator (PVASI)

The PVASI is a rare approach lighting aid that has been replaced at many airports. Houston West airport (KIWS) still has one on runway 15, it's interesting to use on a dark night. It's in FS, try it.🙂

Any idea of how many there are...is this a US thing? Having flown in the UK and US I have not seen one...or even heard of one during ground school. Very interesting.

Not sure how many are left and I think it's only in the US. They were replaced by the PAPI. I think the story was that they were easily confused with other airport and surrounding lights. 🙂

Interesting concept. I hope the red / white lights are distinct and don't go a pink colour, in transition like some.

It's in Flight Simulator, go to KIWS and fly it. 🙂

I see, weird.

I flew around the airport and icame across some areials, i couldnt believe how tall they were, over 2000ft!

if anyone lives in this area, please tell me if this may be true.

That aerial cant be too proportion, look at the size, it would dwarf the Eifel Tower! lol.

One that size would be visible from Google Earth, I cant see it... anyone else.

Good point there "Air-Head" about the Eifel Tower.

I guess its Just another M$ F$9 Scenery Error

Flight Simulator has it correct, I think they're very thin TV station antennas. They are 2049 feet MSL(above sea level) and 1970 feet above the ground. I saw them when I lived in Houston. They are on the Houston sectional chart, 10 miles Southwest of KHOU. HUB 240 radial/10 miles. 🙂
