Next time

Work on the flare

See Arrival Landing

You crossed the threshold slow. Without the speed there is little energy left to round out with, so the flare comes up short and the touchdown tends to be firm - and that feels exactly like flaring too late. Resist the fix that feels natural, flaring earlier: it bleeds off more speed and makes the next landing firmer still. Fly the approach speed all the way to the threshold, and the flare has something to work with.

Speed and pitch

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

Lifted off at 63 kt with 6.2° 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.

Side view from the start of the roll to 333 ft. The distance scale changes past the runway end.

Reached 35 ft at the runway end; then climbing at 1,060 fpm on average to 333 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.

Plan view the roll down the 376 m runway.

Rolled from 55 m in, drifted 18 m left of the centreline and was back on it to lift off. Airborne 73 % 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 approach to 85U 25

The final from 4 nm.

Profile height against the 3° glideslope, with its 2° band in green.

On the glideslope from 2.7 nm, where the final began, to 1.3 nm, then low to 0.3 nm (up to 390 ft under), then back on it to the threshold.

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.

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.

The crosswind

Little crosswind (1 kt): nothing to correct for. Touched down with the nose 1° right of the track, wings level.

Wind 275° at 4 kt · 4 kt head · 1 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 51 kt at touchdown to taxi speed (30 kt) in 9 s, an average deceleration of 0.12 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 410 m of the approach.

Touched down 70 m in, 235 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 410 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 230 fpm at 4 ft to 80 fpm at touchdown. The nose came up 3.0° 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 410 m runway, to the same scale as the side view.

Touched down 27 m left of the centreline, and stayed about there down the rollout, 19 m left at the widest.

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.
