Keep the approach speed on target
Every knot above Vref is stored kinetic energy, and energy stored at the threshold must be dissipated in ground effect before the aeroplane will stop flying. Because kinetic energy scales with the square of speed, the excess you must dissipate grows fast. At a 45-knot approach, five knots hot is over a tenth more speed and roughly a quarter more energy to get rid of in ground effect. This is why the fix is never in the flare. It was decided three miles earlier, on final, at the airspeed indicator.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
One stabilised approach gate: five checks where the approach path is 500 ft above the runway. The 1,000 ft gate was not assessed, because the approach did not join final that far out.
Side view — the last 3,465 ft of the approach.
Plan view — the full 3,465 ft runway, to the same scale as the side view.
The 875 ft touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The flight in the Sirius began with a departure roll from runway 22 at ID41 Stibnite. The takeoff distance was 1,077 ft, representing 49% of the runway length. The liftoff speed was 59 kn. The local weather at the time of departure was 37 °F, with a 4 kn wind coming from 273° resulting in a crosswind of 3 kn and a headwind of 3 kn.
The enroute climb commenced overhead ID41 Stibnite Yellow Pine in Idaho, United States. The aircraft climbed from 7,035 ft asl to 8,597 ft asl, an increase of 1,563 ft over 2 minutes, covering a distance of 2 nm.
The enroute descent began 2 miles west of ID41 Stibnite Yellow Pine. The aircraft descended from 8,605 ft asl to 6,676 ft asl, a decrease of 1,929 ft over 2 minutes, covering a distance of 3 nm.
The landing took place on runway 17 at 3U2 Johnson Creek with a runway length of 3,465 ft. The height at threshold was 62 ft agl and the speed at threshold was 81 kn. The touchdown occurred 874 ft from the threshold at a speed of 72 kn with a VSI of -235 ft/m. The local weather at the time of landing was 40 °F, with a 3 kn wind coming from 251° resulting in a crosswind of 2 kn and a headwind of 1 kn. The total landing distance was 1,723 ft, representing 50% of the runway length.
Overall, the total flight distance was 9 nm, taking 61 minutes and utilizing 3 lbs of fuel.
