Like their Asiana 214 analysis, Sooeet did a new analysis for UPS 1354, including nice plots of position and airspeed. It's darned good,
I tend to agree with firesysok: that article is dodgy.
If Soooeeet's plot is to be believed, it's plainly obvious the crew couldn't see the runway because the track deviates well left from a long way out. It's claim that weather was not a factor appears itself to be a furphy. The crew either couldn't see the runway or were majorly distracted by something in/with the aircraft.
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.
What is this rubbish? Intercepting the PAPI glideslope at 10-15nm? If they are like ours, you can't even see them that far out; at night they are just a white/pink/red blur. And let's not forget that it was Scattered at 1100 and Broken at 3500ft. PAPI would not have been visible.
"Engine power to maintain speed and spoilers to increase descent rate"? And these guys are casting judgement on a dead crew??
