Flight Score
Arrival
Track the centreline through touchdown using small rudder corrections against a point at the far end of the runway.
What happened: The aircraft touched down off the centreline at 14 m, and drifting off centreline at touchdown usually carries through into the rollout, as it did here with alignment reaching 112 m.
Watch for: Watch runway centreline position, keeping deviation inside the limit through touchdown and rollout.
Ground control varies with speed, full authority at walking pace, progressively reducing as groundspeed rises. The aircraft becomes twitchy at any speed, every small pedal input swings the nose, which can encourage large-amplitude leg inputs that no real aircraft would accept.

From brake release to the end of the climb, against time, then the takeoff point by point.
Rotated at 102 kt, 11 kt above the 91 kt target, and lifted off at 106 kt 1.4 s later, the nose coming up at 4.2° a second. Climb 3 held close to its 161 kt target, at 161 kt on average.
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 dashed green line is the speed to rotate at for this aircraft at its weight, and the green dot is where the nose started to come up. The figures at liftoff are the pitch then and how fast the nose came up, in degrees a second. 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 998 ft.
Reached 35 ft with 1,310 m of runway left; gear up at 16 ft, inside the 400 ft that gets full marks; then climbing at 1,660 fpm on average to 998 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 gear-up ring is coloured by its mark. The shaded stretch is Climb 3, scored on its average speed against the target.
Plan view the roll down the 2,322 m runway.
Rolled from 62 m in, drifted 3.5 m right of the centreline and was back on it to lift off. Airborne 33 % 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 3.5° glideslope, with its 1° band in green.
Inside the glideslope band from 0.8 nm, where the final began, to the threshold, never more than 60 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: 3.5° here, which is about 370 ft for every nautical mile out, crossing the threshold at about 60 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 3× larger than distances along the final.
Inside the 1° band all the way from 0.8 nm, never more than 172 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 24 kt fast at the 1,000 ft gate, closing to 14 at 500 ft and 10 at the threshold.
Slow from 0.8 nm, where the final began, to the threshold (up to −11 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
Perfect landing flare
Little crosswind (1 kt): nothing to correct for. Touched down with the nose 10° left of the track, 2° of bank.
Wind 269° at 2 kt · 1 kt head · 1 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 83 kt at touchdown to taxi speed (30 kt) in 26 s, an average deceleration of 0.11 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 1,524 m of the approach.
Began the flare at 34 ft, 100 m before the threshold; crossed the threshold at 20 ft, 30 ft below the 50 ft target. Touched down 271 m in, close to 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 1,524 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 430 fpm at the flare to 50 fpm at touchdown. The nose came up 2.5° 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 1,524 m of the 1,872 m runway, to the same scale as the side view.
Touched down 16 m right of the centreline, and stayed about there down the rollout, 15 m right at the widest.
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 271 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
