Touched down at 88 fpm — a soft arrival
Touchdown 1,000 ft in — inside the full-score zone
1.12 G at touchdown — inside band

What held you back

Arrival Landing — at 15 %, Landing and flare profile at 41 %, −3.05 points
Arrival Final 1 — Approach angle 0.9 ° at 0 %, bank angle up to 11.3 ° at 78 %, −2.18 points
Departure Roll — landing lights off should be on, then strobe light off should be on; Liftoff speed was 32 kn at 30 %, −1.00 points

Hold the approach angle

See Arrival Final 1

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 31 kt with 9.3° 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 602 ft. The distance scale changes past the runway end.

Reached 35 ft with 1,290 ft of runway left; then climbing at 920 fpm on average to 602 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 2,358 ft runway.

Rolled from 143 ft in, drifted right of the centreline, 10 ft at the widest, and lifted off 6 ft right, in 6 kn of crosswind from the left. Airborne 17 % 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 U72 22

The final from 4 nm.

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

Low from 4 nm to 1.4 nm (up to 1,070 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, 1,000 ft 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 3× larger than distances along the final.

Joined 1,590 ft left of the centreline, then drifted 780 ft right between 2.1 and 0.8 nm, then inside the band from 0.8 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

No wind recorded: nothing to correct for. Touched down with the nose 1° right of the track, wings level.

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 59 kt at touchdown to taxi speed (30 kt) in 6 s, an average deceleration of 0.23 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 2,192 ft of the approach.

Touched down 1,000 ft in, close to the ideal 1,000 ft.

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 2,192 ft across. The dashed line is the ideal, 50 ft over the threshold and down 1,000 ft 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 600 fpm at 20 ft to 90 fpm at touchdown. The nose came up 4.3° 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.

Touched down 6 ft left of the centreline, and stayed within 7 ft of it down the rollout.

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.
