Shorten the long landing
Ground effect becomes significant below about one wingspan of height. A Cessna 172, with a 36 ft span, enters ground effect at flare height - the float it feels in the hold-off is ground effect arriving on cue. An A320, with a span around 117 ft, has been in ground effect since before the threshold and there is no sudden cushion to feel, only a gradual reduction in induced drag that lengthens any float you allow.

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 6,726 ft of the approach.
Plan view — the first 6,726 ft of the 12,130 ft runway, to the same scale as the side view.
Touched down 2,384 ft past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Boeing 777-200ER taxied from the parking area to runway 31R at KJFK, a movement that lasted 9 minutes and covered 2 nm.
During the departure roll on runway 31R at KJFK the aircraft accelerated through a takeoff distance of 5,655 ft, 63 % of the runway, and lifted off at 165 kt. Local weather was temperature 80 °F, wind 3 kt from 290°, with a 1 kt cross-wind and a 3 kt head-wind.
Climb commenced overhead the KNO1 Canarsie waypoint, rising from 1,012 ft asl to 34,936 ft asl - an increase of 33,924 ft - in 23 minutes while covering 165 nm.
The first cruise segment began 7 miles south-west of MA72 Tuckernuck Airport and continued for 467 minutes, during which 4,152 nm were flown.
Descent started 7 miles west of Skiathos, dropping from 35,004 ft asl to 4,431 ft asl - a decrease of 30,574 ft - in 17 minutes and covering 107 nm.
A brief cruise followed 7 miles south-west of Vouliagmeni, lasting 2 minutes and spanning 6 nm.
The second descent began 2 miles south-east of Vouliagmeni, descending from 3,975 ft asl to 1,679 ft asl - a loss of 2,296 ft - in 3 minutes and covering 7 nm.
Final approach to runway 03R at LGAV Athens was executed from the south-west, on a heading of 35.0° at 4 nm and 1,384 ft agl.
Landing on runway 03R, which is 12,130 ft long, occurred with a threshold speed slightly above target at 144 kt. Touchdown was recorded 1,028 ft beyond the touchdown zone, at a speed of 129 kt and a descent rate of minus 185 fpm; the aircraft was offset by 11 ft from the centreline. Local conditions were temperature 78 °F, wind 3 kt from 320°, with a 3 kt cross-wind and a 1 kt head-wind. Total landing distance was 6,470 ft, 53 % of the runway, and runway rollout alignment was perfect.
Runway rollout proceeded without deviation, confirming the perfect alignment noted at touchdown.
The aircraft taxied from the runway to the parking area in 6 minutes, covering 1 nm.
Overall, the flight covered 4,446 nm, required 527 minutes of airborne time, and consumed 125,921 lb of fuel.
The Boeing 777-200ER, scored 98.5%, entered the final approach to runway 03R at LGAV Athens Eleftherios Venizelos International Airport from the south-west on a heading of 35.0 ° at 4 nm and 1,384 ft agl; the approach was assessed as unstable at the 1,000 ft gate because the sink rate was too high, while the local weather was 78 °F with a wind of 3 kt from 320 ° (crosswind 3 kt, headwind 1 kt).
At threshold the height was good and the threshold speed was slightly above target at 144 kt, indicating the aircraft crossed the runway threshold marginally faster than planned.
Touchdown occurred 1,028 ft beyond the touchdown zone; the touchdown speed of 129 kt was good, the touchdown rate was good at minus 185 fpm, and the touchdown point was slightly misaligned by 11 ft from the centreline.
The total landing distance was 6,470 ft, representing 53 % of the 12,130 ft runway, and the runway rollout alignment was perfect.
Refine the approach to achieve a stabilized sink rate by the 1,000 ft gate and aim to reduce the threshold speed to the target value; these adjustments will bring the already high score even closer to optimal performance.
