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 1,802 m of the approach.
Plan view — the first 1,802 m of the 3,623 m runway, to the same scale as the side view.
Touched down 935 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Airbus A350-900 taxied from the parking area to runway 07L at PANC, covering 1 nm in 6 minutes.
During the departure roll on runway 07L, the aircraft accelerated through a takeoff distance of 1,145 m, representing 36 % of the runway, and lifted off at 160 kt. Local weather at the time was 14 °C with a wind of 5 kt from 12°, including a 5 kt crosswind component and a 1 kt headwind.
Climb commenced overhead Lake Hood (LHD) in Anchorage, with the airplane ascending from 1,140 ft asl to 40,997 ft asl, an increase of 39,857 ft achieved in 29 minutes while covering 210 nm.
Level cruise began 38 miles south-west of the 0AA1 Yakataga waypoint and continued for 111 minutes, during which 908 nm were flown.
Descent was initiated 6 miles north-east of Parksville, British Columbia, with the aircraft descending from 41,000 ft asl to 1,708 ft asl, a loss of 39,292 ft in 24 minutes over a distance of 138 nm.
The final approach to runway 16L at KSEA was conducted from the north, on a heading of 180.0° at 4 nm and 1,268 ft agl. Weather at Seattle-Tacoma reported a temperature of 20 °C, wind 7 kt from 199°, a 2 kt crosswind and a 7 kt headwind.
Landing on runway 16L, whose length is 3,623 m, occurred with a threshold speed of 137 kt. Touchdown was recorded 518 m beyond the touchdown zone at a speed of 130 kt, with a touchdown rate of minus 79 fpm. The aircraft’s touchdown point was laterally offset by 15.4 m from the centreline, and the total landing distance measured 1,720 m, equivalent to 47 % of the runway.
During rollout, the aircraft remained misaligned by 15.4 m from the centreline, consistent with the touchdown deviation.
After exiting the runway, the Airbus A350-900 taxied to the parking area in 1 minute, covering less than 1 nm.
In total, the flight covered 1,264 nm, lasted 173 minutes, and consumed 15,456 kg of fuel.
The Airbus A350-900 approached runway 16L at Seattle-Tacoma International Airport from the north on a final approach heading 180.0 ° at 4 nm and 1,268 ft agl, with a temperature of 20 °C, wind 7 kt from 199 °, a 2 kt cross-wind component and a 7 kt head-wind component.
At threshold the aircraft maintained a good threshold height, but the threshold speed was well above target at 137 kt.
Touchdown occurred 518 m beyond the designated touchdown zone; the aircraft touched down at 130 kt, which was a little fast, yet the touchdown rate was excellent at minus 79 fpm. The runway touchdown position was significantly misaligned by 15.4 m from the centreline, and the total landing distance measured 1,720 m, representing 47 % of the 3,623 m runway.
During rollout the aircraft remained misaligned by 15.4 m from the centreline.
Improving lateral alignment on final and at touchdown will reduce the 15.4 m offset observed. Refining speed control to bring the threshold and touchdown speeds closer to target values will further enhance landing precision.
