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.

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 5,000 ft of the approach.
Plan view — the first 5,000 ft of the 5,142 ft runway, to the same scale as the side view.
Touched down 2,063 ft past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The flight began with a taxiing period from the parking to the runway, which took 6 minutes and covered less than 1 nautical mile. The aircraft, a TBM 930, then departed from runway 36R at KDFW Dallas Fort Worth International Airport. The takeoff distance was 835 meters, which is 20% of the runway length. The liftoff speed was 107 knots.
The local weather conditions at the time of departure were a temperature of 9°C, with a wind speed of 4 knots at 350°. The crosswind was 1 knot, and the headwind was 4 knots. The aircraft began its enroute climb 1 mile east of Grapevine, Texas, and climbed from 1,253 feet above sea level to 2,326 feet above sea level, an increase of 1,073 feet in 2 minutes, covering 6 nautical miles.
The enroute level cruise started 1 mile west of Farmers Branch, Texas, and lasted 4 minutes, covering 17 nautical miles. The aircraft then began another enroute climb 2 miles east of KRBD Dallas Executive Airport, climbing from 3,070 feet above sea level to 4,594 feet above sea level, an increase of 1,524 feet in 4 minutes, covering 18 nautical miles.
The enroute level cruise started 1 mile north of Garrett, Texas, and lasted 2 minutes, covering 9 nautical miles. The aircraft then began another enroute climb 5 miles southeast of Ennis, Texas, climbing from 4,797 feet above sea level to 5,437 feet above sea level, an increase of 640 feet in 2 minutes, covering 8 nautical miles.
The enroute level cruise started 1 mile south of 4XS1 Coyote Field Corsicana, Texas, and lasted 44 minutes, covering 171 nautical miles. The aircraft then began its descent 1 mile northeast of Seabrook, Texas, and descended from 5,436 feet above sea level to 1,298 feet above sea level, a decrease of 4,138 feet in 8 minutes, covering 12 nautical miles.
The final approach to runway 31R at KHOU William P Hobby Airport was from the southeast, heading 317.0° at 4 nautical miles and 1,248 feet above ground level. The landing on runway 31R was at a runway length of 1,567 meters. The threshold height at 67 feet above ground level was above the target, and the threshold speed was excessively high at 114 knots.
The touchdown point was 200 meters beyond the touchdown zone, and the touchdown speed at 105 knots was excessively fast. The touchdown rate was fair at -248 feet per minute. The runway touchdown position was slightly misaligned by 7.3 meters from the centerline. The local weather conditions at the time of landing were a temperature of 10°C, with a wind speed of 4 knots at 270°. The crosswind was 3 knots, and the headwind was 3 knots.
The total landing distance was 1,112 meters, which is 71% of the runway length. The runway rollout alignment was misaligned by 20.4 meters from the centerline. The taxiing period from the runway to the parking took 4 minutes and covered less than 1 nautical mile. The total flight distance was 247 nautical miles, taking 78 minutes, and the aircraft used 265 kilograms of fuel.
The TBM 930 aircraft successfully landed on runway 31R at KHOU William P Hobby Airport, but the landing was not without its issues. The final approach was initiated from the southeast, heading 317.0° at 4 nautical miles and 1,248 feet above ground level (agl). The aircraft touched down 200 meters beyond the touchdown zone, which is a significant deviation from the intended landing spot.
The touchdown speed of 105 knots was excessively fast, indicating that the pilot may have been unable to slow the aircraft down sufficiently before touchdown. This is a critical aspect of landing, as excessive speed can lead to a longer rollout distance and increased risk of overrunning the runway. The touchdown rate of -248 feet per minute (fpm) was fair, but it could have been improved with more precise control of the aircraft's descent.
The threshold height at 67 feet agl was above the target, suggesting that the pilot may have been unable to maintain a stable approach path. This could be due to a variety of factors, including wind shear or a lack of experience with the aircraft. The threshold speed of 114 knots was also excessively high, which is a concern as it may indicate that the pilot was not able to slow the aircraft down sufficiently before reaching the threshold.
The runway touchdown position was slightly misaligned by 7.3 meters from the centerline, which is a relatively minor deviation. However, the runway rollout alignment was misaligned by 20.4 meters from the centerline, which is a more significant issue. This could be due to a variety of factors, including a lack of control during the rollout or a failure to properly align the aircraft with the runway centerline.
The local weather conditions at the time of the landing were relatively calm, with a temperature of 10°C and winds of 4 knots at 270°. The crosswind and headwind components were both 3 knots, which is a relatively minor factor in this case. Overall, while the landing was not perfect, the pilot was able to bring the aircraft safely to the ground, albeit with some deviations from the intended landing spot.
