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.
The approach before the go-around was abandoned. Its marks are shown, but only the approach that landed counts.

The crosswind
10 kt across from the right, which takes about 9° of crab to hold the centreline at 63 kt. Touched down with the nose 3° left of the track, away from the wind, 6° of bank.
Wind 226° at 12 kt · 7 kt head · 10 kt across
How to read this
The wind is the one recorded at the landing, split along the runway (headwind or tailwind) and across it. To hold the centreline in a crosswind the nose points a little into wind - the crab - and is straightened with rudder just before the wheels touch, often with the into-wind wing lowered to stop the drift. These are the nose against the direction you were actually moving, and the wings, at the moment of touchdown. Shown for reading; not marked.
The stop
From 62 kt at touchdown to taxi speed (30 kt) in 11 s, an average deceleration of 0.18 g.
How to read this
Your ground speed from the moment the wheels touched until you were down to taxi speed, against the distance rolled. A steep line is hard braking, a shallow one a long, gentle roll. For scale, an airliner's lowest autobrake setting decelerates at about 0.15 g, a medium one about 0.3 g. Shown for reading; not marked.
Your ground speed60 kt and taxi speed
Side view — the last 5,000 ft of the approach.
Crossed the threshold at 39 ft, 11 ft below the 50 ft target. Touched down 1,237 ft in, 237 ft past the ideal 1,000 ft.
How to read this
The last stretch of the approach and the touchdown, from the side. The height is stretched so that the last few feet show: 80 ft top to bottom, against 5,000 ft across. The dashed line is the ideal, 50 ft over the threshold and down 1,000 ft in. The flare ring is where you began raising the nose, and "descent slowed" is where the sink came off; the figures beside them are the sink rate, pitch and speed at that point.
Sink and pitch — through the flare, lined up with the side view.
The sink went from 1,780 fpm at 38 ft to 170 fpm at touchdown. The nose came up 8.2° on the way down.
How to read this
Lined up with the side view above, so a point on one sits under the same point of the other. On top, how fast you were coming down: 0 is level, and −600 is 600 ft a minute down. Below, the pitch. In a flare the nose comes up and the descent slows towards 0. The figure at the touchdown line is your touchdown rate.
Plan view — the full 5,000 ft runway, to the same scale as the side view.
Touched down 210 ft left of the centreline, and steered back to 25 ft left by the end of the rollout.
How to read this
The runway from above, with your left at the top. Touching down inside the green bracket scores full marks for the distance. The shaded part is the rollout, up to where it ended. The arrow beside the runway is the crosswind, pointing the way the air was moving, so it pushed the aircraft that way.
