Zeffy, thanks for the clarification – HUD #353.
However, Re The pilot need only temporarily place the FPV short of the runway until the 3.0-deg GS reference line moves "down" to the desired spot in the TDZ. Typical visual technique is to place the GS reference line on the PAPI. Once the GS reference line is on the PAPI lights, the FPV is moved back "up" to the GS reference line.
If the pilot cannot see or perhaps comprehend where the touchdown zone is, nor perhaps see the PAPI (were they working / installed) then the HUD visual mode might be little more than a distraction. Technology is a wonderful thing, but most systems have limits, even pitfalls.
IMHO (and experience with HUD) it could be quite feasible that if the pilot was using HUD he was concentrating on maintaining a reasonable flight path in the turbulent tailwind conditions that he overlooked the GS reference ‘sliding’ down the runway well beyond a sensible touchdown point.
