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.
The approach, gate by gate
Side view — the last 477 m of the approach.
Plan view — the full 477 m runway, to the same scale as the side view.
Touched down 10 m short of the threshold. The arrival was smooth.
The rest of the report
The Kodiak 100 taxied to runway 04 at AYRM Maramuni Airport and commenced the take-off roll, using 265 m of runway which represented 55 % of the available length. Liftoff was achieved at 67 kt. Ambient conditions were 15 °C with a wind of 1 kt from 271°, a crosswind component of 1 kt and a tailwind component of 1 kt.
Climb began directly overhead AYRM, with the aircraft ascending from 5,154 ft asl to 6,442 ft asl, a gain of 1,288 ft achieved in 1 minute while covering 2 nm.
Cruise was established 3 nm north-east of AYRM and persisted for 3 minutes, during which the aircraft travelled 4 nm at level flight.
Descent commenced 6 nm north-east of AYRM, descending from 6,536 ft asl to 5,292 ft asl, a loss of 1,244 ft in 2 minutes and covering 5 nm.
The final approach to runway 22 at AYRM involved a descent from 151 ft agl to -94 ft agl over a period of 77 seconds, and the aircraft scored on the stabilisation gates.
Landing on runway 22 was executed with a runway length of 477 m; the threshold speed was slightly below the target at 61 kt. Touchdown occurred 81 m down the runway at 53 kt with a touchdown rate of minus 20 fpm and perfect runway alignment. Weather remained 15 °C with a wind of 1 kt from 271°, a crosswind of 1 kt and a headwind component of 1 kt.
Rollout recorded a total landing distance of 385 m, representing 81 % of the runway, and the runway rollout alignment was very good.
In total, the flight covered 14 nm, required 9 minutes of elapsed time, and consumed 20 kg of fuel.
The final approach to runway 22 at AYRM Maramuni Airport descended from 151 ft agl to -94 ft agl in 77 seconds and was scored on the stabilisation gates.
At threshold the height was good and the threshold speed was slightly below target at 61 kt; the local weather was 15 C with wind 1 kt from 271 deg, including 1 kt crosswind and 1 kt headwind.
Touchdown occurred 81 m from the threshold at a speed of 53 kt, which was good, with a touchdown rate of minus 20 fpm that was perfect and runway-touchdown alignment described as perfect.
The rollout covered a total landing distance of 385 m, representing 81 % of the 477 m runway, and runway-rollout alignment was very good.
To bring the score closer to the maximum, adjust the approach to achieve the target threshold speed rather than the slightly low 61 kt, ensuring the speed is within the prescribed band while maintaining the strong alignment and rate already demonstrated.
