Flight Score
Arrival
Reduce power sooner on the approach so your speed is back to 188 kt well before the stabilisation gate.
What happened: This flight was fast at the stabilisation gate, then crossed the threshold high on a shallow descent and 30 kt above VREF; carrying that extra speed through to the threshold usually carries the touchdown long, and this flight touched down 234 m past the target point.
Watch for: Airspeed indicator: 188 kt 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.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
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 500 ft gate: speed 30 kt FAST on the reference speed of 188 kt.
The approach, gate by gate
Side view — the last 2,701 m of the approach.
Plan view — the first 2,701 m of the 3,201 m runway, to the same scale as the side view.
Touched down 691 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Concorde taxied from the parking area to runway 20 at LPPT Humberto Delgado Airport in less than 1 minute, covering less than 1 nm.
During the departure roll on runway 20, the aircraft used 2,060 m of runway, representing 64 % of the available length, and lifted off at 214 kt. Ambient conditions were 26 °C with a wind of 1 kt from 080°, a cross-wind component of 1 kt and a tail-wind component of 1 kt.
Climb commenced overhead Alvalade, rising from 1,179 ft asl to 10,502 ft asl - a gain of 9,324 ft - in 3 minutes while covering 14 nm.
The first cruise segment began 10 nm south-west of Cascais and lasted 8 minutes, during which the aircraft travelled 39 nm.
Descent began 5 nm south of Charneca de Caparica, descending from 10,510 ft asl to 7,020 ft asl - a loss of 3,490 ft - in 3 minutes and covering 17 nm.
A second cruise phase started 1 nm south of Cadaval, persisted for 6 minutes and spanned 27 nm.
The next descent started 2 nm north of LPSC Santa Cruz Airfield Torres Vedras, dropping from 6,987 ft asl to 4,028 ft asl - a decrease of 2,959 ft - in 3 minutes while covering 15 nm.
Final approach to runway 20 at LPPT was executed from the north on a heading of 203.0° at 4 nm and 1,307 ft agl; local weather reported 20 °C with a wind of 3 kt from 296°, a cross-wind of 3 kt and no head-wind component.
Landing on runway 20 occurred with a threshold height of 73 ft agl and a threshold speed of 219 kt. Touchdown was recorded 309 m beyond the touchdown zone at a speed of 209 kt, with a touchdown rate of minus 287 fpm and perfect runway alignment.
Runway rollout alignment remained perfect, and the aircraft used a total landing distance of 2,655 m, representing 83 % of the runway length of 3,208 m.
After landing, the Concorde taxied back to the parking area in 4 minutes, covering less than 1 nm.
In total, the flight covered 119 nm, took 28 minutes, and consumed 25,501 kg of fuel.
The final approach to runway 20 at LPPT Humberto Delgado Airport was flown from the north on a heading of 203.0 ° at 4 nm and 1,307 ft agl, with temperature 20 °C, wind 3 kt from 296 °, a 3 kt cross-wind component and no head-wind. The approach was assessed as unstable at the 1,000 ft gate because the sink rate was too high.
During the threshold and flare phase the aircraft crossed the threshold at a height of 73 ft agl, which was well above the target, and the threshold speed was too high at 219 kt.
Touchdown occurred 309 m beyond the touchdown zone with a speed of 209 kt, which was excessively fast, and a vertical rate of -287 fpm that was rated fair. Runway touchdown alignment was perfect.
The rollout covered a total landing distance of 2,655 m, representing 83 % of the runway, and runway rollout alignment remained perfect.
To improve the 82.2 % score, focus on reducing the approach and threshold speeds to meet target values and managing sink rate to achieve the correct threshold height, which will help place the touchdown nearer the intended aim point and lower the touchdown speed.
