Guys,
The discussion is going around in circles ..
The concern is not when you are landing on a 5000 ft runway .... doesn't matter how much of a botched job is made of the flare.
However, the normal manufacturer's data is based on next to no float ... and not much flare ... if the data is unfactored or only factored nominally and is not based on the higher "normal" speed, then the "normal" approach speed is (not may .. IS) going to put you beyond the book landing distance figures.
This sort of ignorance has bent more than a few aircraft over the years .. including a business jet in Oz when the rules were changed some years ago ..... Centaurus is not trying to stir an argument .. rather his intention is to highlight a problem which is largely hidden due to the bulk of training operations being conducted from runways which are not distance critical.
