MY FS FLIGHTS
Flight Score
Arrival
Fly a slightly steeper descent on final so you cross the threshold at 50 ft rather than above it.
What happened: The aircraft crossed the threshold 34 ft agl above 50 ft agl, carried extra speed through the flare instead of losing it, and touched down well beyond the aim point. Crossing the threshold high like this usually carries through to extra speed at touchdown and a touchdown point long of the target.
Watch for: Radio altimeter: 50 ft at the threshold.
Even a modest height error carries straight through to the touchdown. Geometry alone says that crossing the threshold 10 feet high on a 3° path moves your touchdown roughly 190 feet further down the runway before the flare adds anything.

From brake release to the end of the climb, against time, then the takeoff point by point.
Rotated at 168 kt, 8 kt above the 160 kt target, and lifted off at 177 kt 2.6 s later, the nose coming up at 1.7° a second. Climb 3 averaged 196 kt, 6 kt under its 202 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 972 ft.
Reached 35 ft with 1,758 m of runway left; gear up at 108 ft, inside the 400 ft that gets full marks; then climbing at 2,170 fpm on average to 972 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 3,889 m runway.
Rolled from 59 m in, drifted 3.6 m right of the centreline and was back on it to lift off. Airborne 48 % 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.
When the approach was stable
Every check met from 4 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 3° glideslope, with its 1° band in green.
Inside the glideslope band from 4 nm to the threshold, never more than 50 ft above the slope.
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 21× larger than distances along the final.
Inside the 1° band all the way from 4 nm, never more than 18 m off the centreline.
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 36 kt fast at the 1,000 ft gate, closing to 21 at 500 ft and 10 at the threshold.
Inside the speed band all the way, between +2 kt and +13 kt on the approach speed of 142 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. The aircraft was flown onto the runway - pitch changed 0.5° and the descent was barely arrested. Touchdown was 567 m past the threshold. Start the flare with progressive back pressure rather than one pull, and keep it coming.
6 kt across from the right, which takes about 2° of crab to hold the centreline at 147 kt. Touched down with 2° of it still on, wings level.
Wind 240° at 10 kt · 7 kt head · 6 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 155 kt at touchdown to taxi speed (30 kt) in 37 s, an average deceleration of 0.18 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 1,694 m of the approach.
Crossed the threshold at 83 ft, 33 ft above the 50 ft target; began the flare late, at 8 ft. Touched down 567 m in, 263 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 1,694 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 stayed between 470 fpm and 510 fpm from the flare to the runway. The pitch barely changed.
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 1,694 m of the 3,981 m runway, to the same scale as the side view.
Touched down 2.1 m left of the centreline, and stayed within 2.6 m of it down 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 567 m past the threshold — beyond the full-score zone. The 484 fpm arrival was firm.
The rest of the report
The Airbus A350-1000 taxied from the parking area to runway 27R at EGLL London Heathrow Airport in 5 minutes, covering less than 1 nm.
Take-off was performed on runway 27R. The aircraft used 1,865 m of runway (48 % of the available length) and rotated at 168 kt. Local weather was 12 °C with wind 4 kt from 010°, a 4 kt cross-wind and a 1 kt tailwind component.
Initial climb to 1,000 ft agl took 24 seconds, averaging 1,990 fpm and reaching 203 kt at the top of the segment. The climb continued from 1,106 ft asl to 33,673 ft asl in 25 minutes, covering 173 nm, beginning overhead Colnbrook.
The aircraft level-flew at 34,200 ft asl for 748 minutes, covering 4,674 nm, starting 1 mile north-east of Beaufai.
Descent began at 34,281 ft asl and proceeded to 6,845 ft asl in 26 minutes, covering 157 nm, starting 11 miles south of FBNR Mookane Airport, with a brief level-off at 8,300 ft asl.
Final approach to runway 21R at FAOR O.R. Tambo International Airport descended from 1,362 ft agl to 123 ft agl in 111 seconds. Stabilisation checks at 1,000 ft and 500 ft above the runway were met for gear down, landing flap, sink rate, glideslope, centreline, speed and wings level. Configuration was gear down at 3,120 ft agl at 237 kt; final flap position 4 was selected at 2,927 ft agl at 205 kt.
Landing on runway 21R (runway length 3,981 m) had a threshold height of 84 ft agl, which was significantly above target, while the threshold speed of 144 kt was good. The flare was very poor, with little round-out. Touchdown occurred 160 m beyond the touchdown zone at 147 kt, a little fast, with a hard rate of -485 fpm. Runway-touchdown alignment was very good and there was no bounce. Total landing distance was 1,611 m (40 % of the runway) and rollout alignment was perfect. Local weather was 29 °C with wind 16 kt from 239°, a cross-wind of 11 kt and a head-wind component of 11 kt.
After landing, the aircraft taxied to the parking area in 4 minutes, covering less than 1 nm.
The flight covered a total of 5,012 nm in 618 minutes and used 77,348 kg of fuel.
