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 149 kt with 11.7° 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 984 ft.
Reached 35 ft with 1,263 m of runway left; then climbing at 1,540 fpm on average to 984 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 3,806 m runway.
Rolled from 107 m in, never more than 1.4 m off the centreline. Airborne 60 % 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.
The final from 4 nm.
Profile height against the 3° glideslope, with its 1° band in green.
Inside the glideslope band from 4 nm to the threshold, never more than 180 ft above the slope.
Your height above the runway against the distance still to go. The glideslope is the steady descent path to the aiming point, 305 m past the threshold: 3° here, which is about 320 ft for every nautical mile out, crossing the threshold at about 50 ft. The row under the distances is the height it puts you at. Inside the green band your path is drawn green; outside it, amber.
Plan distance off the extended centreline, your left at the top, with the 1° band. Sideways distances are drawn 4× larger than distances along the final.
Inside the 1° band all the way from 4 nm, never more than 89 m off the centreline.
Looking down from above, flying left to right towards the runway: up the page is left of the centreline, down is right. Sideways distances are stretched so that small drifts show, so a line that looks wild here may be only a few tens of feet. The labels are how far off you were at each distance, amber when outside the band.
Speed against the approach speed. The green band runs from 5 kt slow to 32 kt fast at the 1,000 ft gate, closing to 18 at 500 ft and 10 at the threshold.
Inside the speed band all the way, between +5 kt and +30 kt on the approach speed of 139 kt.
Your indicated airspeed down the final, against the approach speed for this aircraft at its landing weight. The band allows 5 kt slow and more on the fast side further out, closing as you get lower, because the speed is expected to come off on the way down. The figures are knots above (+) or below (−) the approach speed.
Over the threshold
Touchdown
Calm: nothing to correct for. Touched down with the nose 7° right of the track, 6° of bank.
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 140 kt at touchdown to taxi speed (30 kt) in 27 s, an average deceleration of 0.22 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 1,834 m of the approach.
Crossed the threshold at 33 ft, 17 ft below the 50 ft target. Touched down 565 m in, 260 m past the ideal 305 m.
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 1,834 m across. The dashed line is the ideal, 50 ft over the threshold and down 305 m 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 640 fpm at 31 ft to 240 fpm at touchdown. The nose came up 1.7° 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 first 1,834 m of the 2,995 m runway, to the same scale as the side view.
Touched down 3.8 m left of the centreline, and steered back to 0.7 m right 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.
Touched down 565 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The flight began with a taxiing period from the parking to the runway, which took 13 minutes and covered a distance of 4 nautical miles. The aircraft, a Boeing 737-800, then departed from runway 14R at SKBO El Dorado International Airport in Bogota, Colombia. The takeoff distance was 2,180 meters, which accounted for 57% of the runway. The liftoff speed was 149 knots.
The local weather conditions at the time of departure were characterized by a temperature of 22 degrees Celsius and a wind speed of 2 knots from a direction of 30 degrees. This resulted in a crosswind of 2 knots and a headwind of 0 knots. The aircraft then began its enroute climb, starting 2 miles south east of the airport and reaching an altitude of 16,912 feet above sea level. The climb was a significant one, with an increase of 7,549 feet in just 4 minutes, covering a distance of 19 nautical miles.
Following the initial climb, the aircraft entered a level cruise phase, which lasted for 2 minutes and covered a distance of 9 nautical miles. This cruise phase started 5 miles south west of Tena, Colombia. The aircraft then began another climb, this time from 17,022 feet to 34,988 feet above sea level, an increase of 17,966 feet in 22 minutes, covering a distance of 161 nautical miles. This climb started 2 miles south east of Apulo, Colombia.
The aircraft then entered another level cruise phase, which lasted for 31 minutes and covered a distance of 246 nautical miles. This cruise phase started 3 miles north west of Boavita, Colombia. The aircraft then began its descent, starting overhead SVGE Ganadería Pedernales Airport in Venezuela. The descent was significant, with a decrease of 32,098 feet in just 19 minutes, covering a distance of 109 nautical miles.
The final approach to runway 10 at SVVA Arturo Michelena International Airport was made from the west, with a heading of 92.0 degrees at a distance of 4 nautical miles and an altitude of 1,448 feet above ground level. The landing was successful, with a touchdown point 153 meters beyond the touchdown zone. The touchdown speed was 134 knots, which was considered good, while the touchdown rate was fair at -243 feet per minute. The runway touchdown position was slightly misaligned by 4.3 meters from the centerline.
The local weather conditions at the time of landing were characterized by a temperature of 26 degrees Celsius and a wind speed of 0 knots from a direction of 93 degrees. This resulted in a crosswind of 0 knots and a headwind of 0 knots. The total landing distance was 1,757 meters, which accounted for 59% of the runway. The runway rollout alignment was very good.
The taxiing period from the runway to the parking took just 1 minute and covered a distance of less than 1 nautical mile. The total flight distance was 556 nautical miles, taking a total of 90 minutes to complete. The aircraft used a total of 4,242 kilograms of fuel during the flight.
