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: seven checks where the approach path is 300 ft above the runway. The 1,000 ft gate was not assessed, because the approach did not join final that far out.
At the 300 ft gate: wings not level.
The approach, gate by gate
Side view — the last 1,524 m of the approach.
Plan view — the first 1,524 m of the 2,131 m runway, to the same scale as the side view.
The 339 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The Embraer E175 aircraft took off from runway 01 at KDCA Ronald Reagan Washington National Airport, departing after a 7-minute taxi from the parking area, covering a distance of 1 nautical mile. The takeoff distance was 940 meters, which accounted for 43% of the runway. The aircraft lifted off at a speed of 145 knots.
The local weather conditions at the time of departure were characterized by a temperature of 3 degrees Celsius, with a wind speed of 12 knots at 320 degrees. This resulted in a crosswind of 7 knots and a headwind of 10 knots. The aircraft began its enroute climb overhead RB16 Washington Potomac Washington, ascending from 1,026 feet above sea level to 21,006 feet above sea level, an increase of 19,980 feet in 9 minutes, covering a distance of 53 nautical miles.
The enroute level cruise started 3 miles northwest of Queenstown, Maryland, and lasted for 5 minutes, covering a distance of 60 nautical miles. The aircraft then began its enroute descent 1 mile southwest of Elmer, New Jersey, descending from 21,001 feet above sea level to 4,021 feet above sea level, a decrease of 16,980 feet in 9 minutes, covering a distance of 80 nautical miles.
The enroute level cruise started 1 mile southeast of Fort Wadsworth, New York, and lasted for 2 minutes, covering a distance of 5 nautical miles. The aircraft then began its final descent overhead Park Slope, New York, descending from 3,510 feet above sea level to 181 feet above sea level, a decrease of 3,329 feet in 4 minutes, covering a distance of 10 nautical miles.
The final approach to runway 31 at KLGA LaGuardia Airport was made from the southeast, heading 300.0 degrees at 0 nautical miles and 160 feet above ground level. The aircraft landed on runway 31, which had a length of 2,131 meters. The threshold height was good, and the threshold speed was well above the target at 138 knots.
The touchdown distance was good at 341 meters, but the touchdown speed was a little fast at 128 knots. The touchdown rate was fair at -260 feet per minute. The runway touchdown position was slightly misaligned by 4.5 meters from the centerline. The local weather conditions at the time of landing were characterized by a temperature of 2 degrees Celsius, with a wind speed of 18 knots at 320 degrees. This resulted in a crosswind of 5 knots and a headwind of 17 knots.
The total landing distance was 1,068 meters, which accounted for 50% of the runway. The runway rollout alignment was perfect. The aircraft then taxied to the parking area from the runway, taking 4 minutes to cover a distance of less than 1 nautical mile. The total flight distance was 213 nautical miles, taking 39 minutes, and the aircraft used 1,190 kilograms of fuel.
The Embraer E175 aircraft successfully landed at LaGuardia Airport (KLGA) on runway 31, achieving a score of 98.5%. The final approach was initiated from the southeast, heading 300.0° at 0 nm and 160 ft above ground level (agl). The aircraft's approach to the runway was precise, with a good threshold height, indicating that the pilots maintained a safe distance from the runway surface.
Upon touchdown, the threshold speed was significantly above the target speed, reaching 138 kt. This suggests that the pilots may have been able to flare the aircraft more aggressively, resulting in a shorter touchdown distance. The actual touchdown distance of 341 m was within acceptable limits, demonstrating the pilots' ability to control the aircraft's descent and speed.
However, the touchdown speed of 128 kt was slightly faster than desired, which may have contributed to a fair touchdown rate of -260 fpm. A faster touchdown speed can result in a more significant impact on the aircraft's landing gear and potentially affect the overall safety of the landing.
The runway touchdown position was slightly misaligned by 4.5 m from the centreline, which may have been due to a slight deviation in the pilots' alignment during the final approach. Despite this, the runway rollout alignment was perfect, indicating that the pilots were able to maintain control of the aircraft during the rollout phase.
The local weather conditions at the time of the landing were characterized by a temperature of 2 °C, with a wind speed of 18 kt at 320°. The crosswind component was minimal at 5 kt, while the headwind component was 17 kt. These conditions may have contributed to the pilots' ability to maintain a stable approach and landing.
Overall, the Embraer E175 aircraft's landing at LaGuardia Airport was successful, with the pilots demonstrating a high level of skill and control throughout the approach and landing phases. However, there were some minor deviations from the desired touchdown speed and runway alignment, which may be addressed through further training and practice.
