Reduce your height at the threshold
Even a modest height error carries straight through to the touchdown. Geometry alone says that crossing the threshold 10 feet high on a 3° path moves your touchdown roughly 190 feet further down the runway before the flare adds anything.

Two stabilised approach gates, each with five checks, where the approach path is 1,000 ft and 500 ft above the runway.
The approach, gate by gate
Side view — the last 1,524 m of the approach.
Plan view — the first 1,524 m of the 2,713 m runway, to the same scale as the side view.
Touched down 849 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Cessna 750 Citation X taxied from the parking area to runway 28L at KSFO, a movement that lasted 9 minutes and covered 2 nm.
During the departure roll on runway 28L the aircraft accelerated over a distance of 678 m, representing 20 % of the runway, and lifted off at 144 kt. Local conditions were a temperature of 23 °C, wind 27 kt from 280°, with an 8 kt cross-wind component and a 25 kt head-wind.
Climb commenced overhead KSFO, climbing from 988 ft asl to 36 997 ft asl - an increase of 36 010 ft - in 20 minutes while covering 122 nm.
Cruise began 10 miles east of 3CA7 Metz Airport and continued for 10 minutes, during which 87 nm were flown at level altitude.
Descent was initiated 8 miles east of KLOS Lost Hills Airport, descending from 36 998 ft asl to 1 381 ft asl - a loss of 35 617 ft - in 23 minutes and traversing 126 nm.
The final approach to runway 24R at KLAX was flown from the east on a heading of 263.0°, intercepting the glide path at 4 nm and 1 243 ft agl.
Landing on runway 24R, which is 2 713 m long, occurred with a threshold height of 76 ft agl and a threshold speed of 121 kt. Touchdown was recorded 422 m beyond the touchdown zone at 109 kt, with a vertical speed of minus 184 fpm and perfect runway-centerline alignment. Weather at the time was 26 °C, wind 10 kt from 250°, with a 2 kt cross-wind and a 10 kt head-wind.
Runway rollout covered a total landing distance of 1 326 m, equivalent to 49 % of the runway, and alignment remained perfect throughout the rollout.
After landing, the aircraft taxied from the runway to the parking area in 10 minutes, traveling 3 nm.
In total the flight covered 345 nm, required 73 minutes of elapsed time, and consumed 898 kg of fuel.
The Cessna 750 Citation X established a final approach to runway 24R at KLAX from the east, tracking a heading of 263.0° at 4 nm and 1,243 ft agl. Local weather was 26 °C with wind 10 kt from 250°, including a 2 kt crosswind component and a 10 kt headwind component.
At the threshold the aircraft was 76 ft agl, which was well above the target height, and the threshold speed was good at 121 kt.
Touchdown occurred 422 m beyond the touchdown zone; the speed at touchdown was 109 kt, a little fast, while the vertical rate was good at minus 184 fpm and runway touchdown alignment was perfect.
The total landing distance was 1,326 m, representing 49 % of the runway, and rollout alignment remained perfect.
Refine the final-approach altitude to meet the intended threshold height and adjust the flare to place touchdown nearer the 300 m aim point. Trim speed to bring touchdown speed closer to the target VREF.
