Plan view the roll down the 3,602 m runway.

Rolled from 112 m in, drifted right of the centreline, 23 m at the widest, and lifted off 23 m right. Airborne 65 % 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.

Side view from the start of the roll to the end of Climb 3 at 953 ft.

Reached 35 ft with 1,006 m of runway left; then climbing at 2,470 fpm on average to 953 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.

Speed and pitch from brake release to the end of the climb, against time.

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 grey dashed line across the pitch is the attitude held from 35 ft to the end: a nose held steady is a climb speed that holds, and the airspeed trace sits directly above it to compare. The shaded stretch is Climb 3, the part of the climb scored on holding the climb speed.

The approach to KBOS 33L

The final from 4 nm.

Profile height against the 3° glideslope, with its 1° band in green.

On the glideslope from 4 nm to 1.3 nm, then low to the threshold (up to 170 ft under).

How to read this

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 52× larger than distances along the final.

Inside the 1° band all the way from 4 nm, never more than 6 m off the centreline.

How to read this

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.

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

Crossed the threshold at 8 ft, 42 ft below the 50 ft target. Touched down 163 m in, 142 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 210 fpm at 8 ft to 160 fpm at touchdown. The pitch barely changed. Into 8 ft at 134 kt and 130 kt at touchdown.

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 first 1,524 m of the 2,911 m runway, to the same scale as the side view.

Touched down 1.7 m right of the centreline, and stayed within 2.8 m of it down the rollout. No crosswind: nothing to correct for. Touched down with the nose 2° left of the track, wings level.

Wind 299° at 18 kt · 18 kt head · 0 kt across

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 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. The sentence gives the nose against the direction you were actually moving as the wheels touched, and the steepest bank as they touched, the figure the touchdown's Bank tile marks. The rest of it is shown for reading, not marked.

The stop — touchdown to taxi speed.

From 107 kt at touchdown to taxi speed (30 kt) in 50 s, an average deceleration of 0.08 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.
