Improve the touchdown
There are several things that can go wrong during the flare, carrying too much speed over the threshold, starting the flare at the wrong height and inconsistent flight control inputs, all contribute to a poor flare resulting in a hard touchdown or a float down the runway.

Two stabilised approach gates, each with six checks at 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 2,561 m runway, to the same scale as the side view.
The 201 m touchdown sits inside the full-score zone. The 1.90 G arrival is the firm side of smooth.
The rest of the report
The Boeing 707-320 taxied from the parking area to runway 27R at EGLL in less than 1 minute, covering less than 1 NM.
During the departure roll on runway 27R, the aircraft accelerated for a takeoff distance of 2,536 m, representing 65 % of the runway, and lifted off at 200 kt. Ambient conditions were 19 °C with a 1 kt wind from 270°, giving a headwind component of 1 kt and no crosswind.
Climb commenced over Colnbrook, England, with the aircraft ascending from 1,063 ft ASL to 35,623 ft ASL, a gain of 34,560 ft achieved in 11 minutes while covering 72 NM.
Level cruise began over Eastington, England, and was maintained for 373 minutes, during which the aircraft traversed 2,853 NM.
Descent was initiated over Ashaway, Rhode Island, United States, with a reduction from 35,992 ft ASL to 666 ft ASL, a loss of 35,326 ft accomplished in 17 minutes and spanning 119 NM.
The final approach to runway 04R at KJFK was flown from the southwest on a heading of 32.0° at 2 NM and 641 ft AGL.
Landing on runway 04R at KJFK occurred on a runway 2,561 m long; the threshold speed was 164 kt, and touchdown was recorded at 197 m from the threshold with a speed of 163 kt. The aircraft touched down with a heavy rate of minus 1,019 fpm and was laterally displaced 33.9 m from the centreline. Weather at the time was 15 °C with a 1 kt wind from 270°, providing a 1 kt tailwind and a 1 kt crosswind.
The total landing roll measured 1,142 m, equivalent to 45 % of the runway length, and the rollout alignment was off by 310.5 m from the centreline.
After exiting the runway, the aircraft taxied to the parking area in 15 minutes, covering a distance of 2 NM.
In total, the flight covered 3,051 NM, required 418 minutes, and consumed 55,724 kg of fuel.
The Boeing 707-320 approached runway 04R at KJFK from the south-west on a heading of 32.0° at 2 nm and 641 ft agl, with temperature 15 °C, wind 1 kt from 270°, a 1 kt crosswind and a 1 kt tailwind. The final approach was recorded with a score of 74.1 % and the aircraft remained on the correct glide path to the runway threshold.
At threshold the height was reported as good, but the threshold speed was well above target at 164 kt.
Touchdown occurred 197 m down the runway at a speed of 163 kt, which was fast, and the vertical rate was very heavy at minus 1,019 fpm. The touchdown point was excessively misaligned by 33.9 m from the centreline, and the total landing distance measured 1,142 m, representing 45 % of the available runway.
During rollout the aircraft remained excessively misaligned, deviating 310.5 m from the centreline.
Future landings would benefit from tighter centreline control during flare and rollout to keep the touchdown point within a few metres of the centreline, and from moderating the descent rate to achieve a lighter vertical speed while maintaining the appropriate touchdown speed near VREF.
