What went well

Touched down at -165 fpm — a soft arrival
Straight touchdown — 1.05 m off the centreline, no bounce
Flare on profile — 100 %

What held you back

Departure Taxi — peak taxi speed 39 kt at 57 %, −1.15 points
Arrival Approach — overspeed warning, then GPWS warning; 1,000 ft gate 83 %, 500 ft gate 83 %, −1.11 points
Arrival Landing — GPWS warning; Threshold speed was too high at 142 kt at 70 %, −0.51 points

Next time

Arrival

Reduce power earlier on final so the speed settles to 117 kt before the gate.

What happened: The approach was 39 kt fast at the stabilisation gate, and carrying that extra speed over the threshold usually carries the touchdown long, which happened here by 272 m.

Watch for: Airspeed indicator: 117 kt at the threshold.

See Arrival ApproachArrival 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 129 kt, on the 128 kt target, and lifted off at 142 kt 3.5 s later, the nose coming up at 1.9° a second. Climb 3 averaged 181 kt, 12 kt over its 169 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 795 ft.

Reached 35 ft with 2,247 m of runway left; gear up at 60 ft, inside the 400 ft that gets full marks; then climbing at 1,240 fpm on average to 795 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 3,623 m runway.

Rolled from 74 m in, drifted left of the centreline, 2.5 m at the widest, and lifted off 1.5 m left. Airborne 28 % of the way down the runway, before the 75 % line.

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.

When the approach was stable

Never every check met at once: fast all the way.

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 KSFO 28R

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 140 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.

Plan distance off the extended centreline, your left at the top, with the 1° band. Sideways distances are drawn 11× larger than distances along the final.

Inside the 1° band all the way from 4 nm, never more than 34 m off the centreline.

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 18 at 500 ft and 10 at the threshold.

Fast from 4 nm to the threshold (up to +76 kt).

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. Crossing the threshold 25 kt above target, the aircraft floated down the runway before touching. Touchdown was 729 m past the threshold. The flare cannot burn off excess energy - fix the approach speed and the float goes with it.

The crosswind

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

Wind 270° at 4 kt · 4 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 121 kt at touchdown to taxi speed (30 kt) in 53 s, an average deceleration of 0.09 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 1,652 m of the approach.

Crossed the threshold at 40 ft, close to the 50 ft target; began the flare at 25 ft. Touched down 729 m in, 424 m past 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 1,652 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 320 fpm at the flare to 160 fpm at touchdown. The nose came up 1.7° 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.

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.
