What went well

Touchdown 315 m in — inside the full-score zone
Threshold crossed at 29 ft and 117 kt — both inside band
Straight touchdown — 2.83 m off the centreline, no bounce

What held you back

Departure Climb 3 — bank angle up to 31.8 ° at 66 %, climb speed 158 kt against 188 kt at 80 %, −0.99 points
Arrival Touchdown — Touchdown rate was -448 fpm at 46 %, bank angle up to 4.4 ° at 75 %, −0.88 points
Arrival Landing — Flare profile at 68 %, −0.57 points

Next time

Departure

Lower the nose and add power to accelerate back to climb speed.

What happened: Climb speed was slower than the target during the climb.

Watch for: Airspeed indicator against climb speed target.

Arrival

Keep the back pressure coming through the flare so the sink does not return at 246 fpm.

What happened: The flare arrested the sink, but then the sink returned before touchdown.

Watch for: Watch the VSI in the flare and keep arrested sink from returning before touchdown at 448 fpm.

Between four hundred and a thousand feet you're heavy, close to the ground and still carrying flap, and speed is the margin holding all three apart. Slow here doesn't feel like anything — the aeroplane climbs, the nose is up, nothing complains — right up until a turn, a gust or a bank tightens the wing's job and the margin is already gone. The fix is rarely "fly faster", it's lowering the nose a degree and letting the speed build before the next thing you do. Pitch buys altitude, speed buys options, and at this height options are the scarcer of the two.

Speed and pitch

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

Lifted off at 127 kt with 7.9° of pitch. Climb 3 averaged 158 kt, 30 kt under its 188 kt target.

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 824 ft.

Reached 35 ft with 1,469 m of runway left; gear up at 16 ft, inside the 400 ft that gets full marks; then climbing at 2,170 fpm on average to 824 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 gear-up ring is coloured by its mark. The shaded stretch is Climb 3, scored on its average speed against the target.

Plan view the roll down the 2,801 m runway.

Rolled from 101 m in, drifted 4.3 m right of the centreline and was back on it to lift off. Airborne 34 % 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 stabilisation gates

Two stabilised approach gates, each with seven checks, where the approach path is 1,000 ft and 500 ft above the runway. They are the approach's score: the checks passed out of the checks that ran.

When the approach was stable

Every check met from 4 nm to the threshold.

How to read this

Each line is one of the gate checks, run along the whole final rather than only at the gates: green where it would have passed, amber where it would not. The glideslope, centreline and speed lines use the bands in the charts beside this card. The sink rate is allowed what the glideslope needs at your ground speed plus 600 fpm, the wings 10° of bank, and the gear and flap are read from when you moved the levers. The bottom line is green where every check held at once, ignoring blips shorter than 0.2 nm, and the sentence above it says from where it held to the threshold. A ring is a stabilisation gate, where the checks in the table were taken.

The approach to WBGG 07

The final from 4 nm, with the stabilisation gates on it.

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

Inside the glideslope band from 4 nm to the threshold, never more than 160 ft below the slope.

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. A ring is a stabilisation gate: green when every check there passed, amber with the failed checks named beside it.

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.

Speed against the approach speed. The green band runs from 5 kt slow to 29 kt fast at the 1,000 ft gate, closing to 17 at 500 ft and 10 at the threshold.

Your indicated airspeed down the final, against the approach speed for this aircraft at its landing weight. The band allows 5 kt slow and more on the fast side further out, closing as you get lower, because the speed is expected to come off on the way down. The figures are knots above (+) or below (−) the approach speed.

The flare68.03

The flare wandered off the target profile. The flare took all the sink out 20 ft agl above the runway and the aircraft then dropped the rest of the way, 246 fpm of sink coming back. Touchdown was 315 m past the threshold. Hold the attitude and let it settle rather than pushing - a balloon is almost always excess speed, so the fix is on the approach, not in the flare.

The crosswind

5 kt across from the right, which takes about 3° of crab to hold the centreline at 102 kt. Touched down with 3° of it still on, wings level.

Wind 110° at 8 kt · 6 kt head · 5 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 99 kt at touchdown to taxi speed (30 kt) in 29 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 1,524 m of the approach.

Began the flare high, at 58 ft, 162 m before the threshold; crossed the threshold at 29 ft, 21 ft below the 50 ft target. Touched down 315 m in, close to 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 750 fpm at the flare to 130 fpm at 23 ft, then back up to 450 fpm at touchdown. The nose came up 4.2° 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.

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.
