Human Factors; Procedure
I was the flying pilot during the event. We were flying the ILS Z RWY 36 approach to SEQM. The autopilot (VNAV PTH) engaged and we started the descent to 10500 feet after [passing] R-223. I did not have sufficient drag out which allowed the aircraft to accelerate to maintain descent rate. We would arrive high at QSV. After receiving a terrain message I disconnected the autopilot and adjusted the pitch attitude. The remainder of the approach was hand flown in day visual conditions.
B757 First Officer experienced increasing airspeed as the aircraft descended on the approach path after passing the 223 Radial during the ILS Z Runway 36 at SEQM. The descent rate required to catch up triggered a GPWS warning. The remainder of the approach was hand flown.
