Keep the taxi smooth
Turn speed is limited by lateral load on the tyres and the people in the back, and lateral acceleration goes with the square of speed. On an illustrative 25 m turn radius, 10 kt produces about 0.11 g of side load, while 20 kt produces about 0.43 g. Doubling the speed quadruples the load. That square law is the entire content of the "10 knots in turns" rule, and it tells you why a slightly-too-fast turn feels fine and a moderately-too-fast one throws the cabin crew across the galley.

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 1,665 m runway, to the same scale as the side view.
The 273 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 12 minutes and covered a distance of 2 nautical miles. The aircraft then departed from runway 09 at KMMH Mammoth Yosemite Airport, with a takeoff distance of 1,046 meters, which accounted for 49% of the runway. The liftoff speed was 82 knots.
The local weather conditions at the time of departure were characterized by a temperature of 1 °C, with a wind speed of 24 knots blowing from 259°. This resulted in a crosswind of 12 knots and a tailwind of 21 knots. The aircraft then began its enroute climb, starting 2 miles east of KMMH Mammoth Yosemite Airport, and climbed from an altitude of 7,823 feet above sea level to 25,572 feet above sea level, an increase of 17,749 feet, in 14 minutes and covering a distance of 20 nautical miles.
Following the enroute climb, the aircraft entered a level cruise phase, which started 7 miles south of Round Valley, California, and lasted for 144 minutes, covering a distance of 607 nautical miles. The enroute descent then began 1 mile southwest of ID13 Sky Island Ranch Airport, St Maries, Idaho, and the aircraft descended from an altitude of 24,686 feet above sea level to 3,374 feet above sea level, a decrease of 21,312 feet, in 20 minutes and covering a distance of 63 nautical miles.
The final approach to runway 20 at KSZT Sandpoint Airport was made from the northeast, with a heading of 212.0°, at a distance of 4 nautical miles and an altitude of 1,238 feet above ground level. The landing on runway 20 was successful, with a touchdown distance of 273 meters, which was good, and a touchdown speed of 90 knots, which was fast. The touchdown rate was fair at -222 feet per minute, and the runway touchdown alignment was very good.
The local weather conditions at the time of landing were characterized by a temperature of 4 °C, with a wind speed of 6 knots blowing from 180°. This resulted in a crosswind of 3 knots and a headwind of 5 knots. The total landing distance was 529 meters, which accounted for 32% of the runway. The runway rollout alignment was perfect, and the taxiing to the parking from the runway took less than 1 minute and covered a distance of less than 1 nautical mile.
The total flight distance was 699 nautical miles, and the flight duration was 189 minutes. The aircraft used 435 kilograms of fuel during the flight.
The aircraft in question, a M500, successfully landed at KSZT Sandpoint Airport, with a final approach from the north east at a heading of 212.0°. The aircraft was at an altitude of 1,238 feet above ground level (agl) and 4 nautical miles from the runway at the time of the approach. The pilot demonstrated excellent control and precision, as evident from the very good runway touchdown alignment.
Upon touchdown, the aircraft's speed was slightly above the target threshold speed, registering at 100 knots. However, the touchdown distance of 273 meters was considered good, indicating a smooth and controlled descent. Unfortunately, the touchdown speed of 90 knots was faster than desired, which may have contributed to a slightly higher touchdown rate of -222 feet per minute (fpm). Despite this, the pilot managed to maintain a fair touchdown rate, showcasing their ability to adapt to changing circumstances.
The local weather conditions at the time of the landing were relatively calm, with a temperature of 4°C and a wind speed of 6 knots from 180°. The crosswind component was minimal at 3 knots, while the headwind component was 5 knots, which likely contributed to the aircraft's slightly faster touchdown speed. The total landing distance of 529 meters was 32% of the runway length, indicating a relatively short landing roll.
The most impressive aspect of the landing was the perfect runway rollout alignment, which demonstrated the pilot's exceptional control and precision. This is a testament to their skill and experience, as well as the aircraft's handling characteristics. Overall, the landing was considered successful, with the pilot demonstrating a high level of proficiency and control throughout the approach and touchdown phases.
