T-VASIs without tears

[johnl]

Many years ago, Australia came up with a wonderful landing aid called T-VASI, which was technically superior to the VASI and PAPI systems. Some antipodean runways, even in FS, still have it, and it's worth checking out the GAAR destinations to see if it occurs in your scenery, as mistakes in identification can be embarrassing (though fun for the spectators). My own setup has T-VASI approachs on YBCG runways 14/32 (leg 10).

Pilots (especially newcomers to the GAAR) should bear in mind that:-
(1) T-VASIs have no red lights, but lots of WHITE ones.
(2) If your approach is too high, the T-VASI array displays as an inverted "T" with 1/2/3 lights in the vertical leg indicating that you are slightly high/high/very high.
(3) If your approach is correct, the T-VASI array displays as a horizontal bar (actually 2 pairs of white lights). If you haven't done your homework,this may lead you to assume that you are too high on a PAPI or VASI approach....
(4) If your approach is too low, the T-VASI array displays as an upright "T" with 1/2/3 lights in the vertical leg indicating that you are slightly low/low/very low.

Please fly (and land) safely, then you'll be able to enjoy the barbie, the beer, and the fireworks (OOOOH!!! AAAAAH!!).

So does YARG as I landed there at the end of the test flights. I wondered what was wrong with their VASI but I flew it visually as far as glide path went.
