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.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
One stabilised approach gate: five checks where the approach path is 500 ft above the runway. The 1,000 ft gate was not assessed, because the approach did not join final that far out.
Side view — the last 1,524 m of the approach.
Plan view — the first 1,524 m of the 2,207 m runway, to the same scale as the side view.
The 255 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The flight in the Boeing 737-800 began with a short 2-minute taxi from the parking area to the runway at SBTE Senador Petrônio Portela Airport. The departure roll took place on runway 02, with a takeoff distance of 1,205 meters, covering 54% of the runway. The liftoff speed was 148 knots. The local weather at the time of departure was reported as 27°C, with a 2-knot wind coming from 120°, resulting in a crosswind of 2 knots and a tailwind of 1 knot.
Once airborne, the enroute climb began 1 mile north of SBTE Senador Petrônio Portela Airport, climbing from 1,307 feet above sea level to 39,367 feet, covering a total distance of 259 nautical miles in 43 minutes. The enroute level cruise phase commenced 16 miles north of Montes Altos and lasted for 217 minutes, covering a total distance of 1,798 nautical miles.
The descent phase started 23 miles northwest of Diego de Almagro, descending from 40,093 feet to 2,303 feet over a span of 12 minutes and 74 nautical miles. The landing took place on runway 17 at SCAT Desierto de Atacama Airport, with a runway length of 2,207 meters. The height at the threshold was 19 feet above ground level, with a speed of 122 knots. The touchdown occurred 257 meters from the threshold at a speed of 117 knots and a vertical speed indicator reading of -79 feet per minute. The local weather at the time of landing was 16°C, with a 2-knot wind coming from 19°, resulting in a crosswind of 1 knot and a tailwind of 1 knot. The total landing distance covered was 714 meters, equivalent to 32% of the runway length.
After landing, a short 1-minute taxi was conducted from the runway to the parking area. The total flight distance traveled was 2,139 nautical miles, taking a total of 282 minutes and consuming 12,461 kilograms of fuel.
