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 3,847 m runway, to the same scale as the side view.
The 432 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The flight on the Boeing 737-800 began with a smooth taxi from the parking area to the runway, taking 3 minutes to cover less than 1 nm. The departure roll on runway 31L at KPSP Palm Springs International Airport was successful, with a takeoff distance of 940 meters, which accounted for 56% of the runway. The liftoff speed was 140 knots. Despite a local temperature of 19°C, the wind conditions were calm with 0 knots of wind at 69°, resulting in no crosswind or headwind.
The enroute climb commenced 1 mile northeast of Palm Springs, climbing from 1,485 feet above sea level to 39,999 feet above sea level, covering 252 nm in 30 minutes. The level cruise phase commenced 2 miles west of Coolidge and lasted 113 minutes, covering 1,162 nm. The descent phase started 5 miles east of Hatley, descending from 39,452 feet asl to 1,883 feet asl in 14 minutes, covering 83 nm.
Final approach to runway 36L at KHSV Huntsville International Carl T Jones Field was from the south, maintaining a heading of 1.0° at 4 nm and 1,240 feet above ground level. The landing on runway 36L was successful, with a runway length of 3,847 meters. The touchdown was good at a distance of 432 meters, with a speed of 117 knots and a rate of -235 feet per minute. The runway touchdown alignment was very good.
The total landing distance was 899 meters, which accounted for 23% of the runway, with a perfect runway rollout alignment. The taxi back to the parking area from the runway was quick, taking less than 1 minute to cover less than 1 nm. The total flight distance was 1,504 nm, lasting 161 minutes and consuming 7,170 kg of fuel. Overall, the flight was executed smoothly with successful takeoff, climb, cruise, descent, and landing phases.
