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.

From brake release to the end of the climb, against time, then the takeoff point by point.
Lifted off at 55 kt with 5.9° of pitch.
Two traces from brake release: the airspeed on top, and below it the pitch, which is how far the nose is above the horizon. The figure at liftoff is the pitch then. The shaded stretch is Climb 3, the part of the climb scored on holding the climb speed.
The takeoff, point by point
Side view from the start of the roll to the end of Climb 3 at 511 ft.
Reached 35 ft with 2,935 ft of runway left; then climbing at 470 fpm on average to 511 ft.
The takeoff from the side: the height above the runway against the distance along it. The numbers along the runway are the speeds reached at each point. Lifting off in the amber last quarter of the runway costs marks for the roll length. The shaded stretch is Climb 3, scored on its average speed against the target.
Plan view the roll down the 5,502 ft runway.
Rolled from 1,333 ft in, drifted left of the centreline, 584 ft at the widest, and lifted off 519 ft left, in 6 kn of crosswind from the left. Airborne 34 % of the way down the runway, before the 75 % line.
The roll from above, with your left at the top. The line is where the wheels went, and "widest" is the furthest you drifted off the centreline. Lifting off before the amber 75 % line gets full marks for the roll length. The arrow beside the runway is the crosswind, pointing the way the air was moving, so it pushed the aircraft that way.
Over the threshold
Touchdown
3 kt across from the right, which takes about 4° of crab to hold the centreline at 45 kt. Touched down with the nose 5° into wind, wings level.
Wind 317° at 8 kt · 7 kt head · 3 kt across
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.
From 39 kt at touchdown to taxi speed (30 kt) in 6 s, an average deceleration of 0.08 g.
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.
Side view — the last 5,000 ft of the approach.
Crossed the threshold at 50 ft, close to the 50 ft target. Touched down 1,085 ft in, close to the ideal 1,000 ft.
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 550 fpm at 49 ft to 40 fpm at touchdown. The nose came up 5.1° on the way down.
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 116 ft left of the centreline, and steered back to 25 ft left by the end of the rollout.
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.
The 1,085 ft touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The flight began with a departure roll from runway 02 at KUZA Rock Hill - York County Airport, where the Icon A5 aircraft took off with a takeoff distance of 552 feet, which accounted for 10% of the runway. The liftoff speed was 55 knots, and the aircraft quickly gained altitude.
As the aircraft entered the local weather conditions, it was noted that the temperature was a pleasant 75 degrees Fahrenheit, with a wind speed of 11 knots coming from a direction of 320 degrees. This resulted in a crosswind of 8 knots and a headwind of 7 knots. The pilot took advantage of these conditions to begin the enroute level cruise, which started 1 mile southwest of Tega Cay, South Carolina. This cruise lasted for 2 minutes and covered a distance of 2 nautical miles.
After the cruise, the aircraft began its final approach to landing at Bethel-Lake Wylie Airport. The approach was initiated from 1 nautical mile away and descended to an altitude of 230 feet above ground level. As the aircraft approached the touchdown point, it began its descent from 50 feet above ground level to 0 feet, a decrease of 50 feet in just 14 seconds. The touchdown speed was a good 45 knots, and the touchdown rate was perfect at -46 feet per minute.
The touchdown distance was also satisfactory at 1,078 feet, and the local weather conditions remained the same, with a temperature of 75 degrees Fahrenheit and a wind speed of 8 knots coming from a direction of 316 degrees. This resulted in a crosswind of 3 knots and a headwind of 7 knots. After touchdown, the aircraft began its landing rollout, which covered a distance of 263 feet and ended at an altitude of 567 feet above sea level.
Finally, the aircraft taxied to the parking area from the runway, a journey that took 3 minutes and covered less than 1 nautical mile. The total flight distance was 5 nautical miles, and the flight lasted for 8 minutes, using a total of 1 pound of fuel.
