Shorten the long landing
Ground effect becomes significant below about one wingspan of height. A Cessna 172, with a 36 ft span, enters ground effect at flare height - the float it feels in the hold-off is ground effect arriving on cue. An A320, with a span around 117 ft, has been in ground effect since before the threshold and there is no sudden cushion to feel, only a gradual reduction in induced drag that lengthens any float you allow.

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 2,566 m of the approach.
Plan view — the first 2,566 m of the 3,042 m runway, to the same scale as the side view.
Touched down 1,213 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The flight began with the aircraft, a British Aerospace 146-200, taxiing from the parking area to the runway at KSBD San Bernardino International Airport. This process took 4 minutes and covered a distance of 1 nautical mile. The aircraft then departed from runway 24, with a takeoff distance of 728 meters, which accounted for 24% of the runway. The liftoff speed was 121 knots.
The local weather conditions at the time of takeoff were characterized by a temperature of 18 degrees Celsius, with a wind speed of 17 knots at a direction of 19 degrees. This resulted in a crosswind of 13 knots and a tailwind of 11 knots. The aircraft then began its enroute climb, starting overhead KSBD San Bernardino International Airport, and climbed from an altitude of 2,112 feet above sea level to 6,386 feet above sea level, an increase of 4,274 feet, in 3 minutes and covering a distance of 11 nautical miles.
The enroute level cruise started 2 miles west of Fontana, California, and lasted for 9 minutes, covering a distance of 46 nautical miles. The aircraft then began its enroute descent, starting 2 miles northwest of Beverly Hills, and descended from 6,405 feet above sea level to 2,421 feet above sea level, a decrease of 3,984 feet, in 2 minutes and covering a distance of 7 nautical miles.
The aircraft then began another enroute climb, starting 2 miles southeast of Topanga, and climbed from 2,422 feet above sea level to 6,395 feet above sea level, an increase of 3,974 feet, in 4 minutes and covering a distance of 12 nautical miles. The enroute level cruise then started overhead Hollywood, and lasted for 9 minutes, covering a distance of 46 nautical miles.
The aircraft then began its final descent, starting 1 mile east of Fontana, and descended from 6,418 feet above sea level to 1,462 feet above sea level, a decrease of 4,957 feet, in 3 minutes and covering a distance of 9 nautical miles. The final approach to runway 24 at KSBD San Bernardino International Airport was made from the northeast, with a heading of 252.0 degrees at an altitude of 281 feet above ground level.
The landing on runway 24 was characterized by a touchdown point that was 567 meters beyond the touchdown zone, with a touchdown speed of 122 knots, which was a little fast. The touchdown rate was fair at -224 feet per minute, and the runway touchdown alignment was perfect. The local weather conditions at the time of landing were characterized by a temperature of 16 degrees Celsius, with a wind speed of 0 knots at a direction of 90 degrees.
The total landing distance was 2,255 meters, which accounted for 74% of the runway. The runway rollout alignment was also perfect. The aircraft then taxied to the parking area from the runway, taking 4 minutes and covering a distance of less than 1 nautical mile. The total flight distance was 136 nautical miles, taking 40 minutes, and the aircraft used 1 kilogram of fuel.
The British Aerospace 146-200 aircraft successfully landed at San Bernardino International Airport (KSBD) on runway 24. The final approach was initiated from the north-east, heading 252.0° at an altitude of 281 feet above ground level (agl) and 0 nautical miles from the runway. The aircraft's approach was characterized by a slightly high threshold height, exceeding the target by 113 feet agl, and a threshold speed that was too high at 159 knots.
Upon touchdown, the aircraft landed 567 meters beyond the designated touchdown zone, which is a significant deviation. The touchdown speed of 122 knots was also a bit faster than ideal, indicating that the pilot may have been unable to fully arrest the aircraft's descent. However, the touchdown rate of -224 feet per minute (fpm) was considered fair, suggesting that the pilot was able to maintain some control over the aircraft's descent.
The local weather conditions at the time of the landing were favorable, with a temperature of 16°C and a wind speed of 0 knots from 90°. This meant that there was no crosswind or headwind to contend with, making the landing slightly easier. The runway touchdown alignment was perfect, indicating that the pilot was able to maintain a stable approach and touchdown.
The total landing distance of 2,255 meters was 74% of the available runway length, which is a relatively high percentage. This suggests that the pilot may have been unable to fully utilize the available runway length, possibly due to the high touchdown speed and distance beyond the touchdown zone. The runway rollout alignment was perfect, indicating that the pilot was able to maintain control of the aircraft during the rollout phase.
Overall, while the landing was successful, there were some areas for improvement, including a high threshold height, high threshold speed, and a touchdown speed that was a bit too fast. The pilot may have benefited from a more precise approach and touchdown, as well as a more controlled descent to minimize the landing distance.
