"Additionally, UPS1354 flew well above the PAPI glide-slope for runway 18 until about 15 nautical miles out, at which time UPS1354 began a very rapid descent while maintaining 300 knots, likely using a combination of engine power to maintain speed, and spoilers to increase descent rate. UPS1354 attempted to intercept the PAPI glide-slope from above by means of this rapid descent between 15 and 10 nautical miles from the runway touch down zone"
..."likely using a combination of engine power to maintain speed, and spoilers to increase descent rate."
