Some interesting points about the VOR approach into SXM.
If descending to an MDA of 770 feet the VDP distance is 2.2 DME.
If descending to an MDA of 500 feet the VDP distance is 1.5 DME.
So if WestJet was descending to 770 feet, the prevailing visiblity might not have enabled the runway to be visible.
Clearly though, the aircraft was below 770 feet on the go-around.
Probably descended below MDA, broke out below the 3 degree path, and executed a go-around.
