I seem to recall that CCS (Caracas) is quite interesting!
Landing there some years ago in a B747-400 on what was then runway 09, but now seems to be 10, I was in the P3 position on my first visit when I witnessed the rad alt call out '100' followed instantly by '30', by which tie it was almost too late to flare, and a positive arrival followed.
This was caused by a ravine running up to almost the threshold, and the TCH was quite low anyway.
I stored this away and when landing there a couple of days later I must have been about half a dot high on the glide. The RA called 100 so I flared, only for it to call '50' about a second later, by which time I was at Vref and decreasing! We landed ok at about Vref-5 or so, but I was grateful for the mass and momentum of the B747 that saved the day!
