Next time

Departure

Make small rudder corrections against a point at the far end to hold the centreline.

What happened: During the ground roll you drifted 17 m off the runway centreline.

Watch for: Watch runway alignment against the centreline, correcting with small rudder inputs.

See Departure Roll

Arrival

Fly a slightly steeper approach path to cross the threshold at 50 ft agl instead of 137 ft agl.

What happened: The aircraft crossed the threshold at 137 ft agl against a 50 ft agl target, above the normal profile. This fault pattern is often followed by a long touchdown beyond the target point, and here the aircraft touched down at 1,196 m against a 457 m target.

Watch for: Radio altimeter against the 50 ft threshold crossing target on short final.

See Arrival LandingArrival Touchdown

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.

Rotated at 166 kt, 5 kt above the 161 kt target, and lifted off at 174 kt 3.2 s later, the nose coming up at 1.8° a second. Climb 3 averaged 174 kt, 8 kt over its 166 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 dashed green line is the speed to rotate at for this aircraft at its weight, and the green dot is where the nose started to come up. The figures at liftoff are the pitch then and how fast the nose came up, in degrees a second. 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 876 ft.

Reached 35 ft with 1,196 m of runway left; gear up at 476 ft, inside the 698 ft that gets full marks; then climbing at 2,040 fpm on average to 876 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 4,014 m runway.

Rolled from 164 m in, drifted right of the centreline, 17 m at the widest, and lifted off 18 m right, in 5 kn of crosswind from the right. Airborne 60 % 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 six 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.

At the 1,000 ft gate: gear still up, sink rate more than 600 fpm beyond what the glideslope needed and centreline more than 1° off.

At the 500 ft gate: centreline more than 1° off and speed more than 5 kt below the approach speed of 160 kt.

When the approach was stable

Never every check met at once: gear up until 2.8 nm, sinking too fast until 2.8 nm, right of the centreline until 1.1 nm, slow from 2.3 nm and high from 0.7 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.

On the glideslope from 4 nm to 0.7 nm, then high to the threshold (up to 100 ft over).

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.

How to read this

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 flare100.00

The flare tracked the target profile exactly. The aircraft floated down the runway before touching. Touchdown was 1,196 m past the threshold. Threshold speed was not the cause here - hold the aim point on the approach and let the aircraft settle rather than holding it off, and the touchdown comes back to the numbers.

The crosswind

Little crosswind (2 kt): nothing to correct for. Touched down with the nose 3° right of the track, wings level.

Wind 354° at 3 kt · 2 kt head · 2 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 68 kt at touchdown to taxi speed (30 kt) in 5 s, an average deceleration of 0.39 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.

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.

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.
