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 5,000 ft of the approach.
Plan view — the first 5,000 ft of the 7,641 ft runway, to the same scale as the side view.
The 1,227 ft 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 7 minutes and covered a distance of 2 nautical miles. The aircraft, an Airbus A350-900, then departed from runway 10L at KPBI Palm Beach International Airport. The takeoff distance was 5,178 feet, which accounted for 65% of the runway. The liftoff speed was 155 knots.
As the aircraft took off, it encountered local weather conditions with a temperature of 64°F and a wind speed of 1 knot at 269°. The crosswind was negligible, and there was a slight tailwind of 1 knot. The enroute climb started 1 mile east of KPBI Palm Beach International Airport and involved a significant increase in altitude from 1,027 feet above sea level to 41,661 feet above sea level, a rise of 40,634 feet in 33 minutes and covering a distance of 214 nautical miles.
Following the enroute climb, the aircraft entered a level cruise phase, which lasted 85 minutes and covered a distance of 686 nautical miles. The cruise phase started at a latitude of 30.0184969 and a longitude of -78.577798. The aircraft then began its descent, which started overhead Garden City, New York, and involved a decrease in altitude from 40,133 feet above sea level to 3,032 feet above sea level, a drop of 37,101 feet in 25 minutes and covering a distance of 162 nautical miles.
The aircraft then entered another level cruise phase, which started 6 miles east of Scituate, Massachusetts, and lasted 2 minutes, covering a distance of 7 nautical miles. This was followed by another descent phase, which started 9 miles northeast of Scituate and involved a decrease in altitude from 3,028 feet above sea level to 2,041 feet above sea level, a drop of 987 feet in 2 minutes and covering a distance of 5 nautical miles.
The aircraft then entered another level cruise phase, which started 9 miles southeast of Marblehead, Massachusetts, and lasted 3 minutes, covering a distance of 9 nautical miles. This was followed by another descent phase, which started 1 mile southeast of Swampscott, Massachusetts, and involved a decrease in altitude from 1,992 feet above sea level to 1,016 feet above sea level, a drop of 976 feet in 2 minutes and covering a distance of 4 nautical miles.
The final approach to runway 22L at KBOS Logan International Airport was made from the north, with a heading of 202.0° at 4 nautical miles and 996 feet above ground level. The landing on runway 22L, which had a length of 7,641 feet, was successful, with a threshold height that was good and a threshold speed that was slightly above the target at 134 knots.
The touchdown distance was good at 1,220 feet, but the touchdown speed was a little fast at 133 knots. The touchdown rate was fair at -292 feet per minute, and the runway touchdown alignment was perfect. The local weather conditions at the time of landing were a temperature of 64°F and a wind speed of 17 knots at 210°, with a crosswind of 3 knots and a headwind of 17 knots.
The total landing distance was 3,696 feet, which accounted for 48% of the runway. The runway rollout alignment was also perfect. The taxiing period from the runway to the parking took 3 minutes and covered a distance of less than 1 nautical mile. The total flight distance was 1,095 nautical miles, and the flight duration was 167 minutes. The aircraft used 34,437 pounds of fuel during the flight.
The Airbus A350-900 successfully landed on runway 22L at KBOS Logan International Airport, demonstrating a high level of proficiency in its flight operations. The aircraft approached the runway from the north, heading 202.0° at a distance of 4 nautical miles and an altitude of 996 feet above ground level (agl). This positioning allowed the pilots to maintain a good visual reference of the runway and its surroundings.
Upon landing, the aircraft touched down at a speed of 133 knots, which was slightly above the target threshold speed of 134 knots. However, the touchdown distance of 1,220 feet was well within the acceptable range, indicating a smooth and controlled descent. The touchdown rate of -292 feet per minute (fpm) was fair, suggesting that the pilots could have made some adjustments to achieve a more optimal rate.
The local weather conditions at the time of landing were favorable, with a temperature of 64°F and a headwind of 17 knots at 210°. The crosswind component was minimal at 3 knots, which made the landing even more manageable. The runway length of 7,641 feet provided ample space for the aircraft to decelerate and come to a stop.
The total landing distance of 3,696 feet was 48% of the runway length, which is a relatively short distance considering the aircraft's size and weight. This indicates that the pilots executed a well-coordinated and controlled landing, taking into account the aircraft's performance characteristics and the runway conditions. The runway rollout alignment was also perfect, demonstrating the pilots' ability to maintain control of the aircraft during the critical phase of landing.
Overall, the Airbus A350-900's landing on runway 22L at KBOS Logan International Airport was a textbook example of a well-executed flight operation. The pilots' skills and experience were evident in their ability to navigate the aircraft safely and efficiently, even in the presence of a slight headwind.
