Shorten the long 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.

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 1,891 m of the approach.
Plan view — the first 1,891 m of the 3,564 m runway, to the same scale as the side view.
Touched down 709 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Airbus A350-1000 taxied from the parking area to runway 14L at SKBO El Dorado International Airport in 8 minutes, covering 2 nm.
During the departure roll on runway 14L, the aircraft used 1,690 m of runway, representing 45 % of the available length, and lifted off at 150 kt. Ambient conditions were 17 °C with a wind of 12 kt from 090°, giving a cross-wind component of 7 kt and a head-wind component of 9 kt.
The first en-route climb commenced 1 mile east of SKBO, climbing from 9,384 ft asl to 37,819 ft asl - an increase of 28,434 ft - in 26 minutes while covering 195 nm.
A level cruise began 22 miles east of SKVD Viga Del Fuerte Airport and lasted 16 minutes, during which the aircraft flew 134 nm.
The second climb segment started 7 miles east of MPSE Miraflores Airport, ascending from 37,997 ft asl to 39,000 ft asl - a gain of 1,003 ft - in 3 minutes over 26 nm.
Subsequent cruise operations were initiated 2 miles north of Santa Fe, Panama, and continued for 56 minutes, covering 377 nm.
A third climb was logged from latitude 14.9773651 and longitude -78.5316268, rising from 39,006 ft asl to 40,001 ft asl - an increase of 995 ft - in 2 minutes across 14 nm.
The following cruise segment originated at latitude 15.2268753 and longitude -78.5094758, lasting 63 minutes and traversing 536 nm.
Descent phase one began 65 miles west of MYAB Clarence A. Bain Airport, descending from 39,999 ft asl to 3,993 ft asl - a loss of 36,006 ft - in 22 minutes while covering 142 nm.
A brief cruise followed 5 miles north-west of FA35 Lindbergh's Landing Airport, lasting 3 minutes and covering 14 nm.
Descent phase two started 5 miles north-west of Kendall West, Florida, with the aircraft descending from 3,561 ft asl to 1,299 ft asl - a reduction of 2,262 ft - in 2 minutes over 7 nm.
The final approach to runway 09 at KMIA Miami International Airport was conducted from the west, on a heading of 87.0° at 4 nm and 1,280 ft agl.
Landing on runway 09 employed a runway length of 3,555 m; the threshold speed was 146 kt. Touchdown occurred 294 m beyond the touchdown zone at a speed of 157 kt, with a vertical speed of minus 193 fpm and perfect alignment. Local weather reported 30 °C with a wind of 12 kt from 089°, a cross-wind component of 1 kt and a head-wind component of 12 kt. The total landing distance recorded was 1,811 m, representing 51 % of the runway.
Runway rollout alignment was reported as perfect.
The aircraft taxied from the runway to the parking area in 1 minute, covering less than 1 nm.
In total, the flight covered 1,454 nm, required 191 minutes of elapsed time, and consumed 19,070 kg of fuel.
The Airbus A350-1000 established the final approach to runway 09 at KMIA Miami International Airport from the west on a heading of 87.0° at 4 nm and 1,280 ft agl, with a temperature of 30 °C, wind 12 kt from 89°, a 1 kt cross-wind component and a 12 kt head-wind component.
At threshold the height was good and the threshold speed was well above target at 146 kt.
Touchdown occurred 294 m beyond the touchdown zone; the aircraft was too fast at 157 kt, but the touchdown rate was good at minus 193 fpm and runway touchdown alignment was perfect.
The rollout used a total landing distance of 1,811 m, representing 51 % of the 3,555 m runway, and rollout alignment remained perfect.
Reduce the approach and touchdown speeds toward the target values and aim to achieve touchdown within the designated zone to tighten the landing envelope.
