John asked about how far the airplane will have traveled down the runway at
different touchdown speeds. The best way to determine that is to find videos
of KRs landing on hard-surfaced runways that have standard runway markings.
Better yet, see if you can find videos that KR pilots may have posted where
they have a camera mounted on the airplane or elsewhere, looking out at the
runway as the approach and landing are made. Best of all would be if you could
see the instrument panel (airspeed indicator) as well as the runway markings
during the approach and landing. I'm sure there are some out there, but I'm
not sure where.
There are many places on the web (and in the AIM) where you can find the
spacing and length of standard runway markings and get a good idea of distances
covered during the approach and landing.
