Keep the approach speed on target
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.

Two stabilised approach gates, each with six checks at 1,000 ft and 500 ft above the runway.
The approach, gate by gate
Side view — the last 1,524 m of the approach.
Plan view — the full 1,524 m runway, to the same scale as the side view.
The 97 m touchdown sits inside the full-score zone. The 3.38 G arrival is the firm side of smooth.
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.
The Boeing 787-9 aircraft experienced a challenging landing at a location with coordinates -36.3007837 latitude and 18.6569363 longitude. The final approach to landing began at an altitude of 1,627 feet above ground level (agl) and 1 nautical mile (nm) from the ground, resulting in a score of 41.4%. This score indicates that the landing did not meet the expected standards, likely due to the excessive speed and heavy touchdown rate.
As the aircraft approached the touchdown point, it descended from 34 feet agl to 0 feet agl in a matter of seconds, resulting in a significant decrease in altitude. The touchdown occurred at the same coordinates as the final approach, indicating that the aircraft did not deviate from the intended landing path. However, the touchdown speed of 217 knots (kt) was excessively fast, which contributed to the heavy touchdown rate of -2,136 feet per minute (fpm).
The local weather conditions at the time of landing were characterized by a temperature of 21°C and a wind speed of 35 kt from 253°. The crosswind component was 34 kt, while the headwind component was 8 kt. Despite these challenging weather conditions, the aircraft managed to maintain a relatively short touchdown distance of 97 meters.
After touchdown, the aircraft began its rollout, covering a distance of 1,827 meters. The aircraft's altitude remained at 0 feet above sea level (asl) throughout the rollout phase. Overall, while the landing was not perfect, the aircraft's ability to maintain a short touchdown distance and navigate through challenging weather conditions is a testament to its capabilities.
However, the excessive speed and heavy touchdown rate are areas of concern that need to be addressed to improve the overall landing performance of the aircraft. This may involve adjustments to the flight control inputs, thrust settings, or other factors that contribute to the aircraft's descent and touchdown characteristics.
