GPS approach to RWY 14 at GIG has poor vertical guidance and places aircraft well above a normal VDP to land on RWY 15 with displaced threshold...potentially causing an overrun if landing long due to high approach. The RWY has NO PAPI installed at the new threshold and the VNAV path is much too high at minimums.This approach has all the ramifications of a runway overrun because there is no discernible threshold and there is no PAPI guidance system to assist a visual landing. The glide path for the [VDP] is much too high for the display's threshold.Install a PAPI at the new displaced threshold on this runway...also do not call it RWY 14 as it is still the same RWY 15 it has always been. In addition; paint a discernible new threshold with appropriate markings and remove all other markings prior to the threshold.
B777-200 Captain reported the charted minimums on the temporary RNAV (GNSS) U Runway 14 chart; for SBGL; are too high to enable a safe landing from a VDP.
