Flight Score
Arrival
Be established on the glideslope by the gate, and take the power back earlier on final so the height and the speed come back together. Do not push down for the height: that only adds speed.
What happened: The approach was off the glideslope at the gate, and the aircraft then crossed the threshold at 155 ft agl, 105 ft agl above the 50 ft agl target, and at 192 kt, 43 kt over the 149 kt threshold speed. High and fast together is energy the runway has to absorb, and this touchdown came 575 m beyond the aim point.
Watch for: Glideslope indication at the gate, then airspeed: 149 kt on short final
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.

From brake release to the end of the climb, against time, then the takeoff point by point.
Rotated at 174 kt, 4 kt below the 178 kt target, and lifted off at 189 kt 4.1 s later, the nose coming up at 1.7° a second. Climb 3 averaged 216 kt, 12 kt over its 204 kt target.
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.
The takeoff, point by point
Side view from the start of the roll to the end of Climb 3 at 938 ft.
Reached 35 ft with 474 m of runway left; gear up at 328 ft, inside the 400 ft that gets full marks; then climbing at 1,950 fpm on average to 938 ft.
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 3,053 m runway.
Rolled from 138 m in, drifted 6.7 m left of the centreline and was back on it to lift off. Airborne 70 % of the way down the runway, before the 75 % line.
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.
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.
At the 1,000 ft gate: gear still up and glideslope more than 1° off the runway's 2.8°.
At the 500 ft gate: sink rate more than 600 fpm beyond what the glideslope needed, glideslope more than 1° off the runway's 2.8° and speed more than 24 kt above the approach speed of 161 kt.
When the approach was stable
Never every check met at once: high all the way, gear up until 3.1 nm, banked until 0.9 nm, sinking too fast from 2.1 nm, fast from 1.7 nm and left of the centreline from 0.3 nm to the threshold.
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 final from 4 nm, with the stabilisation gates on it.
Profile height against the 2.8° glideslope, with its 1° band in green.
High from 3.9 nm, where the final began, to the threshold (up to 1,050 ft over).
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: 2.8° here, which is about 300 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 6× larger than distances along the final.
Inside the 1° band from 3.9 nm, where the final began, to 1.3 nm, then drifted 66 m right between 1.3 and 0.5 nm, then back inside it from 0.5 to 0.3 nm, then 30 m left of it from 0.3 nm to the threshold.
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 40 kt fast at the 1,000 ft gate, closing to 24 at 500 ft and 10 at the threshold.
Inside the speed band from 3.9 nm, where the final began, to 1.7 nm, then fast to the threshold (up to +33 kt).
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.
Over the threshold
Touchdown
The flare strayed well off the target profile. Crossing the threshold 43 kt above target, the flare took all the sink out 46 ft agl above the runway and the aircraft then dropped the rest of the way, 411 fpm of sink coming back. Touchdown was 1,032 m past the threshold. Hold the attitude and let it settle rather than pushing - that excess speed is what turns a normal flare into a balloon, so the fix is on the approach, not in the flare.
3 kt across from the left, which takes about 1° of crab to hold the centreline at 172 kt. Touched down with the nose 13° into wind, 4° of bank.
Wind 250° at 4 kt · 3 kt head · 3 kt across
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.
From 171 kt at touchdown to taxi speed (30 kt) in 23 s, an average deceleration of 0.32 g.
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 2,332 m of the approach.
Crossed the threshold at 154 ft, 104 ft above the 50 ft target; began the flare high, at 88 ft. Touched down 1,032 m in, 727 m past the ideal 305 m.
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 2,332 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 1,250 fpm at the flare to 620 fpm at touchdown. The nose came up 2.5° on the way down.
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.
Plan view — the first 2,332 m of the 3,371 m runway, to the same scale as the side view.
Touched down 20 m right of the centreline, and steered back to 9.3 m left by the end of the rollout.
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.
Touched down 1,032 m past the threshold — beyond the full-score zone. The 1.76 G arrival is the firm side of smooth.
The rest of the report
The Boeing 777-300ER taxied from the parking area to runway 21L at MPTO Tocumen International Airport, a taxi of 11 minutes covering 2 nm.
Take-off was on runway 21L, using 2,137 m (70 % of the runway). Rotation occurred at 174 kt. The local weather was 31 °C with wind 2 kt from 251°, giving a 2 kt headwind and a 2 kt crosswind.
Initial climb to 1,000 ft agl took 26 seconds, averaging 1,808 fpm and reaching 218 kt at the top of the segment. The climb continued from 1,047 ft asl to 32,865 ft asl in 22 minutes, covering 150 nm, beginning 2 nm south-east of Pedregal.
Cruise was level at 33,100 ft asl for 336 minutes, covering 2,669 nm, starting 57 nm north-east of Bocas del Toro.
Descent began from 33,071 ft asl to 1,802 ft asl in 21 minutes, covering 118 nm, starting 3 nm north-west of Lockwood.
Final approach to runway 28L at KSFO San Francisco International Airport descended from 1,987 ft agl to 198 ft agl in 73 seconds. Stabilisation checks at 1,000 ft and 500 ft above the runway were met for landing flap, centreline, and wings level; they were not met for gear down, sink rate, glideslope, and speed. Gear was lowered at 1,848 ft agl at 183 kt. Final flap position 6 was selected at 28 ft agl at 175 kt.
Landing on runway 28L (runway length 3,371 m) had a threshold height of 155 ft agl, which was excessively over target, and a threshold speed of 192 kt, which was too high. The flare was poor; the aircraft ballooned in the flare. Touchdown occurred 637 m beyond the touchdown zone, at 172 kt, which was fast, with a heavy rate of -626 fpm. The touchdown point was misaligned by 20.2 m from the centreline. No bounce occurred.
Total landing distance was 2,265 m (67 % of the runway). Runway rollout was slightly misaligned by 13.8 m from the centreline. Local weather at KSFO was 17 °C with wind 4 kt from 250°, giving a 3 kt headwind and a 3 kt crosswind.
After landing, the aircraft taxied to the parking area, a taxi of 10 minutes covering 1 nm.
Overall, the flight covered 2,948 nm in 396 minutes and used 58,748 kg of fuel.
