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.

Two stabilised approach gates, each with six checks at 1,000 ft and 500 ft above the runway. They are the approach's score: the checks passed out of the checks that ran.
Side view — the last 2,424 m of the approach.
Plan view — the first 2,424 m of the 3,762 m runway, to the same scale as the side view.
Touched down 1,873 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Taylorcraft BC-12D departed from runway 07R at PANC Ted Stevens Anchorage International Airport, using a takeoff distance of 606 m which represented 16 % of the available runway. Liftoff was achieved at 59 kt. Ambient conditions were 20 °C with a wind from 224° at 3 kt, a 2 kt crosswind component and a 2 kt tailwind component.
Climb commenced overhead the departure airport, with the aircraft climbing from 173 ft asl to 125 ft asl, an increase of 48 ft, in 1 minutes while covering less than 1 nm.
A go-around was executed on runway 25L at PANC, the aircraft aborting the approach at 0 ft agl before re-establishing a climb.
Subsequent landing was performed on runway 25L, whose total length is 3,762 m. The threshold height at 95 ft agl was significantly above the target and the threshold speed was recorded as 87 kt. Touchdown occurred 1,334 m beyond the touchdown zone with a speed of 44 kt and a descent rate of minus 14 fpm. The touchdown point was offset 12.1 m from the centreline. Local weather remained 20 °C with a wind from 227° at 3 kt, a 2 kt crosswind component and a 2 kt headwind component.
Rollout distance measured 2,220 m, representing 59 % of the runway, and the aircraft’s path was misaligned by 21.4 m from the centreline during the rollout.
In total the flight covered 4 nm, taking 3, and consumed 0 kg of fuel.
The Taylorcraft BC-12D approached runway 25L at PANC in 20 °C conditions with a wind from 227° at 3 kt, including a 2 kt headwind and a 2 kt crosswind, and prepared for landing on the 3,762 m runway.
During the threshold and flare phase the threshold height was recorded at 95 ft AGL, which was significantly above the target, and the threshold speed was excessively high at 87 kt.
Touchdown occurred 1,334 m beyond the designated touchdown zone; the aircraft’s speed at touchdown was 44 kt, described as good, and the vertical rate was perfect at minus 14 fpm. The touchdown point was misaligned by 12.1 m from the centreline.
The rollout covered a total landing distance of 2,220 m, representing 59 % of the runway length, and the runway rollout alignment was misaligned by 21.4 m from the centreline.
To improve the 58.8 % score, reduce the threshold speed and height to meet target values and aim to touch down within the touchdown zone while maintaining centreline alignment throughout the rollout.
