I would assume the crew would use VNAV with a 3° descent angle, which would put them in position for landing as if there was no displaced threshold. At 500' above the airport, the crew would have to disconnect the autopilot and then do some sort of level off or reduced descent rate maneuver to land further down the runway”

Given the NOTAMS I wouldn’t assume they would use VNAV….

It would LNAV and probably some other vertical mode such as V/S to fly a continuous descent…

I have not looked at the plates for what was available for 23 on the night but agree with FlightDetent’s thoughts..

BTW going back to my previous thoughts/comments re F25 vs F30 - whilst F30 almost certainly wouldn’t have saved things on the night it’s perhaps worth considering the choice of F25 and not F30 on a limiting”ish runway was a major source of comment in the report published post the Qantas 744 Bangkok gardening exercise about 20 years ago.
