Where did you get the wind quoted from? I haven't seen it in the report. I've only seen mentioning of 'speed over the ground'
As I said, from the CIAIAC report.
"the surface winds were weak (2-3 kt) and from the south" (Page 147)
"aircraft IBE3415 was some 6 NM away from the runway on final at a ground speed (GS) of 232 kt. The wind was from the NW at around 10 kt" (Page 152)
"The IAS decreased constantly throughout the descent, from 215 kt at the FAP to 155 kt above the threshold" (also Page 152)
which makes me believe the investigators only used data from the radar, and not from the aircraft itself...
"The parameters recorded on the QARs (Quick Access Recorder) on both aircraft were available to investigators. The information obtained was compared against the radar data in order to reconstruct the sequence of events." (Page 148)
