Crew possibly land with >15kts tailwind knowing nothing until at the earliest the flare and depending on experience levels maybe not properly recognising the symptoms at all.
Wild, ridiculous speculation I would say. Even if they realised in the flare they had the option to go around.
did not calculate last TWC as they were short finals.
Most trainers would know that Progress Page 2 has the component you mention. No need to try to calculate anything on short final......of course it is recommended for the PM to have Progress Page 2 displayed during approach in RYR isn't it?
