No, a VASI is two lights (or sets of lights), arranged along the side of a runway, in a "column".
PAPI (Precision Approach Path Indicator) is a set of 4 lights, arranged in a "row" on one side of the runway.
There is also a tri-color, single-light VASI. But, it is not used much in the US.
Thanks for the info, I haven’t been in the cockpit for a few years. But as you point out VASI and PAPI accomplish the same function, providing the pilot with rudimentary glide slope information. This “crash,” failing any subsequent finding that there was a mechanical problem, is simply a pilot screw up! Just look at the descent data that one of the other posters put up. Vertical speed was all over the map! Just glad that more lives were not lost. From the look of the plane, they must have evacuated very quickly.
