Keep the approach speed on target
See Arrival Landing
Every knot above Vref is stored kinetic energy, and energy stored at the threshold must be dissipated in ground effect before the aeroplane will stop flying. Because kinetic energy scales with the square of speed, the excess you must dissipate grows fast. At a 45-knot approach, five knots hot is over a tenth more speed and roughly a quarter more energy to get rid of in ground effect. This is why the fix is never in the flare. It was decided three miles earlier, on final, at the airspeed indicator.

The roll
Liftoff and climb
Plan view the roll down the 3,591 m runway.
Rolled from 69 m in, never more than 1.2 m off the centreline. Airborne 52 % 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.
Side view from the start of the roll to the end of Climb 3 at 966 ft.
Reached 35 ft with 1,344 m of runway left; then climbing at 2,930 fpm on average to 966 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 shaded stretch is Climb 3, scored on its average speed against the target.
Speed and pitch from brake release to the end of the climb, against time.
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 grey dashed line across the pitch is the attitude held from 35 ft to the end: a nose held steady is a climb speed that holds, and the airspeed trace sits directly above it to compare. The shaded stretch is Climb 3, the part of the climb scored on holding the climb speed.
Two stabilised approach gates, each with seven checks, where the approach path is 1,000 ft and 500 ft above the runway.
At the 1,000 ft gate: gear still up, no landing flap set, sink rate more than 600 fpm beyond what the glideslope needed, centreline more than 1° off and speed more than 34 kt above the approach speed of 134 kt.
At the 500 ft gate: gear still up, no landing flap set, glideslope more than 1° off the runway's 3°, centreline more than 1° off and speed more than 20 kt above the approach speed of 134 kt.

Side view — the last 1,524 m of the approach.
Crossed the threshold at 33 ft, 17 ft below the 50 ft target. Touched down 97 m in, 208 m short of 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 1,524 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 stayed between 2,120 fpm and 2,330 fpm from 34 ft to the runway. The pitch barely changed. Into 34 ft at 216 kt, 82 kt over the 134 kt approach speed, and 217 kt at touchdown.
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 full 1,524 m runway, to the same scale as the side view.
Touched down 21 m left of the centreline, and steered back to 7.6 m left by the end of the rollout. 37 kt across from the right, which takes about 10° of crab to hold the centreline at 217 kt. Touched down with 7° of it still on, 2.8° of bank.
Wind 255° at 38 kt · 7 kt head · 37 kt across
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. 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. The sentence gives the nose against the direction you were actually moving as the wheels touched, and the steepest bank as they touched, the figure the touchdown's Bank tile marks. The rest of it is shown for reading, not marked.
The 97 m touchdown sits inside the full-score zone. The 3.38 G arrival bounced.
The rest of the report
The flight began with a departure roll from runway 27R at London Heathrow Airport, EGLL. The Boeing 787-9 aircraft took off with a takeoff distance of 1,871 meters, which was 52% of the runway. The liftoff speed was 173 knots. At the time of departure, the local weather conditions were a temperature of 6 degrees Celsius, with a wind speed of 7 knots at 259 degrees. The crosswind was 1 knot, and the headwind was 7 knots.
As the aircraft climbed, it started its enroute climb overhead Harmondsworth, a location in Greater London, England. The aircraft climbed from an altitude of 1,150 feet above sea level to 5,741 feet above sea level, an increase of 4,591 feet in just 2 minutes, covering a distance of 7 nautical miles. The enroute level cruise then started overhead EGLT Ascot Racecourse Heliport Ascot Heath in Surrey, England, and lasted for 2 minutes, covering another 7 nautical miles.
The aircraft then began another enroute climb, this time from 1 mile west of Send in Surrey, England. It climbed from 5,745 feet above sea level to 35,569 feet above sea level, an increase of 29,824 feet in 18 minutes, covering a distance of 139 nautical miles. The enroute level cruise then started overhead Saint-Germain-la-Campagne in Normandie, France, and lasted for 751 minutes, covering a significant distance of 5,092 nautical miles.
As the aircraft approached its destination, it began its enroute descent, starting 11 miles southwest of Simon's Town in the Western Cape, South Africa. The descent was from 37,725 feet above sea level to 1,650 feet above sea level, a decrease of 36,076 feet in 24 minutes, covering a distance of 118 nautical miles.
The final approach to landing was made from 1 nautical mile to 1 nautical mile at an altitude of 1,627 feet above ground level. The aircraft then approached touchdown at the same location, with a descent from 34 feet above ground level to 0 feet above ground level, a decrease of 34 feet in 0 seconds. Unfortunately, the touchdown speed was excessively fast at 217 knots, and the touchdown rate was very heavy at -2,136 feet per minute.
The aircraft landed safely, with a touchdown distance of 97 meters. The local weather conditions at the time of landing were a temperature of 21 degrees Celsius, with a wind speed of 35 knots at 253 degrees. The crosswind was 34 knots, and the headwind was 8 knots.
After landing, the aircraft taxied to the parking area from the runway, taking 51 minutes and covering a distance of 16 nautical miles. The total flight distance was 5,387 nautical miles, taking 850 hours, and the aircraft used 65,453 kilograms of fuel during the flight.
