See Arrival Final 2

Preparing for a stable approach will give you time to decide on whether to attempt the landing or going around. Too much altitude with a high sink rate will result in carrying too much speed onto the runway. Configuring flaps and the gear late also won't help the speed decay.

Speed and pitch

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

Lifted off at 66 kt with 3.8° 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 736 ft.

Reached 35 ft with 2,496 m of runway left; then climbing at 900 fpm on average to 736 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.

Rolled from 175 m in, drifted left of the centreline, 3 m at the widest, and lifted off 2.9 m left. Airborne 13 % 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 DTTA 19

The final from 4 nm.

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

High from 2.2 nm, where the final began, to 0.8 nm (up to 990 ft over), 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.

Joined 517 m left of the centreline at 2.2 nm, then inside the band from 1.8 nm to the threshold.

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

4 kt across from the left, which takes about 4° of crab to hold the centreline at 53 kt. Touched down with 3° of it still on, wings level.

Wind 140° at 5 kt · 3 kt head · 4 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 58 kt at touchdown to taxi speed (30 kt) in 9 s, an average deceleration of 0.18 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 19 ft, 31 ft below the 50 ft target. Touched down 93 m in, 212 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 450 fpm at 19 ft to 380 fpm at touchdown. The nose came up 1.0° 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.
