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.

Two stabilised approach gates, each with six checks at 1,000 ft and 500 ft above the runway.
The approach, gate by gate
Side view — the last 8,144 ft of the approach.
Plan view — the first 8,144 ft of the 9,422 ft runway, to the same scale as the side view.
Touched down 1,785 ft past the threshold — beyond the full-score zone. The 4.75 G arrival is the firm side of smooth.
The rest of the report
The flight began with a taxiing period from the parking to the runway, which took 14 minutes and covered a distance of 2 nautical miles. The aircraft, an Airbus A340-600, then departed from runway 03 at Portland International Airport (KPDX) in Portland, Oregon. The takeoff distance was 5,652 feet, which was 94% of the runway length. The liftoff speed was 164 knots.
As the aircraft climbed out of KPDX, it began its enroute climb, reaching an altitude of 13,793 feet above sea level (asl) after an increase of 12,259 feet in just 6 minutes. This climb phase covered a distance of 26 nautical miles and started 1 mile northeast of the airport. The aircraft then entered a level cruise phase, lasting 2 minutes and covering 12 nautical miles, 2 miles west of Stevenson, Washington.
The aircraft continued its journey, entering another enroute climb phase 6 miles northeast of Carson, Washington. This climb phase saw the aircraft ascend from 13,999 feet asl to 31,976 feet asl, an increase of 17,977 feet in 9 minutes, covering a distance of 50 nautical miles. Following this, the aircraft entered another level cruise phase, lasting 2 minutes and covering 10 nautical miles, 4 miles northeast of Packwood, Washington.
As the aircraft approached its destination, it began its descent from 31,557 feet asl to 18,354 feet asl, a decrease of 13,203 feet in 10 minutes, covering a distance of 20 nautical miles, 10 miles south of Greenwater, Washington. The aircraft then entered another level cruise phase, lasting 5 minutes and covering 12 nautical miles, 5 miles southwest of Lester, Washington.
The aircraft continued its descent, this time from 18,228 feet asl to 12,642 feet asl, a decrease of 5,586 feet in 7 minutes, covering a distance of 29 nautical miles, 7 miles east of Greenwater, Washington. Following this, the aircraft entered another level cruise phase, lasting 3 minutes and covering 11 nautical miles, 2 miles southeast of Black Diamond, Washington.
As the aircraft approached the final approach phase, it began its descent from 11,958 feet asl to 6,562 feet asl, a decrease of 5,396 feet in 9 minutes, covering a distance of 22 nautical miles, overhead East Hill-Meridian, Washington. The aircraft then entered another level cruise phase, lasting 2 minutes and covering 3 nautical miles, 1 mile southwest of Shoreline, Washington.
The final descent phase began overhead Esperance, Washington, with the aircraft descending from 6,026 feet asl to 2,098 feet asl, a decrease of 3,928 feet in 6 minutes, covering a distance of 15 nautical miles. The aircraft then began its final approach to runway 16C at Seattle-Tacoma International Airport (KSEA), heading 180.0 degrees at 4 nautical miles and 1,651 feet above ground level (agl).
The landing on runway 16C was notable for several factors. The threshold height was excessively over target at 177 feet agl, and the threshold speed was well above target at 155 knots. However, the touchdown distance was good at 1,104 feet, and the touchdown speed at 131 knots was also good. The touchdown rate was very heavy at -2,026 feet per minute (fpm), and the runway touchdown position was excessively misaligned by 485 feet from the centreline.
The total landing distance was 7,199 feet, which was 76% of the runway length. The runway rollout alignment was also excessively misaligned
The Airbus A340-600 aircraft has successfully landed at Seattle–Tacoma International Airport (KSEA) on runway 16C. However, the landing was not without its issues. The final approach to the runway was initiated from the north, heading 180.0° at a distance of 4 nautical miles and an altitude of 1,651 feet above ground level (agl).
Upon landing, the aircraft touched down at a speed of 131 knots, which was within the acceptable range. The touchdown distance of 1,104 feet was also considered good. However, the touchdown rate was excessively heavy at -2,026 feet per minute (fpm), indicating a hard landing. This could potentially cause damage to the aircraft's landing gear and other components.
Another issue with the landing was the excessive misalignment of the runway touchdown position, which was 485 feet off the centreline. This could be due to a variety of factors, including pilot error or issues with the aircraft's navigation systems. The runway rollout alignment was also excessively misaligned by 511 feet from the centreline, which could increase the risk of the aircraft veering off the runway.
The threshold height at 177 feet agl was excessively over target, indicating that the aircraft was higher than expected when it reached the runway threshold. The threshold speed was also well above target at 155 knots, which could be a sign of the aircraft being overpowered or the pilots not managing the descent effectively.
The local weather conditions at the time of the landing were characterized by a temperature of 40°F, which could have affected the aircraft's performance and the pilots' ability to control it. The total landing distance of 7,199 feet was 76% of the runway length, which is within the acceptable range.
Overall, while the Airbus A340-600 aircraft successfully landed at KSEA, there were several issues with the landing that need to be addressed to improve the safety and efficiency of future landings.
