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.
The approach, gate by gate
Side view — the last 1,524 m of the approach.
Plan view — the first 1,524 m of the 3,195 m runway, to the same scale as the side view.
The 463 m touchdown sits inside 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 3 minutes and covered less than 1 nautical mile. The aircraft, a TBM 850, then departed from runway 01 at KSDY Sidney - Richland Regional Airport. The takeoff distance was 771 meters, which accounted for 44% of the runway. The liftoff speed was 98 knots.
As the aircraft climbed, it started its enroute climb 1 mile northwest of Sidney, Montana. The climb took 3 minutes and covered 4 nautical miles, with an increase in altitude from 3,045 feet above sea level to 8,152 feet above sea level, a total increase of 5,107 feet. The enroute level cruise then began 4 miles northwest of KSDY Sidney - Richland Regional Airport and lasted for 52 minutes, covering a distance of 199 nautical miles.
The enroute descent started 13 miles east of Billings, Montana, and took 3 minutes to descend from 7,978 feet above sea level to 4,652 feet above sea level, a decrease of 3,325 feet. The descent covered a distance of 10 nautical miles.
The final approach to runway 28R at KBIL Billings Logan International Airport was made from the east, with a heading of 292.0 degrees at 4 nautical miles and 1,067 feet above ground level. The landing on runway 28R was successful, with a touchdown distance of 462 meters, which was 25% of the runway length. However, the touchdown speed was excessively fast at 88 knots, and the threshold speed was too high at 86 knots.
The runway touchdown position was misaligned by 12.6 meters from the centerline, and the runway rollout alignment was slightly misaligned by 12.3 meters from the centerline. The local weather conditions at the time of landing were a temperature of 19 degrees Celsius, with a wind speed of 7 knots at 249 degrees. The crosswind was 5 knots, and the headwind was also 5 knots.
The taxiing period from the runway to the parking took 1 minute and covered less than 1 nautical mile. The total flight distance was 220 nautical miles, which was covered in 68 minutes, and the aircraft used 191 kilograms of fuel during the flight.
The TBM 850 aircraft successfully landed at KBIL Billings Logan International Airport, achieving a score of 89.7%. The final approach was conducted from the east, heading 292.0° at 4 nautical miles and 1,067 feet above ground level (agl). The aircraft touched down on runway 28R, which has a length of 3,195 meters.
The threshold height was satisfactory, but the threshold speed was too high at 86 knots. This indicates that the pilot may have been able to flare the aircraft more effectively to reduce the touchdown speed. The touchdown distance of 462 meters was considered good, but the touchdown speed of 88 knots was excessively fast. A lower touchdown speed would have been more desirable to reduce the stress on the aircraft's landing gear.
The touchdown rate of -10 feet per minute (fpm) was perfect, indicating that the aircraft was able to touch down smoothly and maintain a stable descent rate. However, the runway touchdown position was misaligned by 12.6 meters from the centerline, which may have been due to a slight deviation in the pilot's alignment during the final approach.
The local weather conditions at the time of the landing were characterized by a temperature of 19°C and a wind speed of 7 knots from 249°. The crosswind component was 5 knots, while the headwind component was also 5 knots. These conditions were relatively calm, which may have contributed to the successful landing.
The total landing distance of 806 meters was 25% of the runway length, indicating that the aircraft was able to stop within a reasonable distance. However, the runway rollout alignment was slightly misaligned by 12.3 meters from the centerline, which may have been due to a slight deviation in the pilot's alignment during the rollout phase. Overall, the landing was considered successful, but there were some areas for improvement, particularly in terms of touchdown speed and alignment.
