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 1,597 m of the approach.
Plan view — the first 1,597 m of the 2,435 m runway, to the same scale as the side view.
Touched down 947 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The flight began with the Airbus A320 taxiing from the parking area to the runway at San Francisco International Airport, taking approximately 8 minutes and covering a distance of 2 nautical miles. Departure roll occurred on runway 28L, with the aircraft taking off after covering 44% of the runway's length. The takeoff distance was 1,470 meters, and the liftoff speed was 169 knots.
As the aircraft climbed to a higher altitude, it encountered local weather conditions with a temperature of 20°C and wind speeds of 28 knots at 269°. The crosswind was 13 knots, and the headwind was 25 knots. The enroute climb started overhead San Bruno, California, and the aircraft ascended from 1,006 feet above sea level to 37,455 feet above sea level, an increase of 36,449 feet in 19 minutes, covering a distance of 94 nautical miles.
The enroute level cruise began 3 miles northeast of the Antelope Valley Ranch Airport in Williams, California, and lasted for 38 minutes, covering a distance of 236 nautical miles. The aircraft then started its enroute descent 12 miles southwest of the Toketee State Airport in Clearwater, Oregon, and descended from 37,485 feet above sea level to 23,553 feet above sea level, a decrease of 13,932 feet in 9 minutes, covering a distance of 56 nautical miles.
The enroute level cruise resumed 8 miles northeast of the Jasper Ridge Airstrip in Jasper, Oregon, and lasted for 2 minutes, covering a distance of 11 nautical miles. The aircraft then began its enroute descent 3 miles southeast of Holley, Oregon, and descended from 22,956 feet above sea level to 1,946 feet above sea level, a decrease of 21,011 feet in 17 minutes, covering a distance of 74 nautical miles.
The final enroute level cruise started 1 mile south of Troutdale, Oregon, and lasted for 2 minutes, covering a distance of 5 nautical miles. The aircraft then began its final approach to runway 28R at Portland International Airport from the southeast, heading 299.0° at 4 nautical miles and 1,289 feet above ground level.
The landing occurred on runway 28R, which had a length of 2,435 meters. The threshold height was well above the target, but the threshold speed was good at 129 knots. The touchdown point was 522 meters beyond the touchdown zone, and the touchdown speed was 118 knots, which was good. However, the touchdown rate was hard at -451 feet per minute.
The runway touchdown position was significantly misaligned by 17.5 meters from the centerline, and the runway rollout alignment was also misaligned by 32.3 meters from the centerline. The local weather conditions at the time of landing were a temperature of 15°C and wind speeds of 10 knots at 320°, with a crosswind of 4 knots and a headwind of 10 knots.
The total landing distance was 1,507 meters, which was 62% of the runway's length. The taxiing to the parking area from the runway took approximately 6 minutes and covered less than 1 nautical mile. The total flight distance was 485 nautical miles, and the flight duration was 103 minutes, with the aircraft using 3,784 kilograms of fuel.
The Airbus A320 aircraft successfully landed on runway 28R at KPDX Portland International Airport, but the landing was not without its challenges. The final approach was initiated from the southeast, heading 299.0° at 4 nautical miles and 1,289 feet above ground level (agl). The aircraft touched down on the runway, but the touchdown point was 522 meters beyond the designated touchdown zone, indicating a slight deviation from the intended landing spot.
The touchdown speed of 118 knots was within the acceptable range, and the threshold speed of 129 knots was also satisfactory. However, the touchdown rate of -451 feet per minute (fpm) was considered hard, suggesting that the aircraft may have experienced a slightly rough landing. The runway touchdown position was significantly misaligned by 17.5 meters from the centerline, which could have contributed to the hard touchdown rate.
The local weather conditions at the time of the landing were relatively calm, with a temperature of 15°C and a wind speed of 10 knots from 320°. The crosswind component was minimal at 4 knots, while the headwind component was 10 knots, which may have affected the aircraft's approach and landing. The total landing distance of 1,507 meters was 62% of the runway length, indicating that the aircraft had sufficient runway remaining for a safe stop.
The runway rollout alignment was also significantly misaligned by 32.3 meters from the centerline, which could have contributed to the overall deviation from the intended landing spot. Overall, while the landing was successful, there were several areas for improvement, including the hard touchdown rate and the misaligned touchdown and rollout positions.
