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.

Speed and pitch

From brake release to the end of the climb, against time, then the takeoff point by point.

Lifted off at 33 kt with 7.7° of pitch.

How to read this

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.

Side view from the start of the roll to the end of Climb 3 at 732 ft. The distance scale changes past the runway end.

Reached 35 ft with 829 m of runway left; then climbing at 840 fpm on average to 732 ft.

How to read this

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 1,086 m runway.

Rolled from 50 m in, drifted right of the centreline, 2.3 m at the widest, and lifted off 2 m right, in 5 kn of crosswind from the right. Airborne 7 % of the way down the runway, before the 75 % line.

How to read this

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 crosswind

Little crosswind (2 kt): nothing to correct for. Touched down with the nose 7° left of the track, 9° of bank.

Wind 265° at 2 kt · 1 kt head · 2 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 32 kt at touchdown to taxi speed (30 kt) in 1 s, an average deceleration of 0.11 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.

Side view — the last 1,524 m of the approach.

Crossed the threshold at 40 ft, close to the 50 ft target. Touched down 125 m in, 180 m short of the ideal 305 m.

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 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 370 fpm at 35 ft to 160 fpm at 13 ft, then back up to 540 fpm at touchdown. The nose went down 2.9° 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 1,524 m runway, to the same scale as the side view.

Touched down on the centreline.

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.
