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.

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 1,524 m of the approach.
Plan view — the first 1,524 m of the 2,542 m runway, to the same scale as the side view.
Touched down 1,311 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The flight began with a taxiing period from the parking area to the runway, which took 19 minutes and covered a distance of 5 nautical miles. The aircraft, an Airbus A321, then departed from runway 34 at Macau International Airport, VMMC. The takeoff distance was 825 meters, which accounted for 31% of the runway length. The liftoff speed was 164 knots.
As the aircraft took off, it encountered local weather conditions with a temperature of 16 degrees Celsius and a wind speed of 20 knots at 350 degrees. The crosswind component was 3 knots, while the headwind component was 20 knots. The aircraft then began its enroute climb, starting 1 mile north of the Macau International Airport, and climbed from 1,038 feet above sea level to 5,858 feet above sea level, an increase of 4,820 feet, in just 2 minutes and covering a distance of 7 nautical miles.
The enroute level cruise started 3 miles northeast of Jida Airport, Jida, and lasted for 2 minutes, covering a distance of 9 nautical miles. The aircraft then began another enroute climb, this time from 5,858 feet above sea level to 36,279 feet above sea level, an increase of 30,421 feet, in 21 minutes and covering a distance of 151 nautical miles. The climb took place 7 miles northwest of Tai O, Hong Kong.
The enroute level cruise started 64 miles north of Pratas Island, Taiwan, and lasted for 18 minutes, covering a distance of 152 nautical miles. The aircraft then began its enroute descent, starting 34 miles southwest of Qimei, Taiwan, and descended from 35,809 feet above sea level to 1,830 feet above sea level, a decrease of 33,978 feet, in 22 minutes and covering a distance of 83 nautical miles.
The final approach to runway 27 at Kaohsiung International Airport, RCKH, was made from the east, heading 272.0 degrees, at a distance of 4 nautical miles and an altitude of 1,774 feet above ground level. The landing was made on runway 27, which had a length of 2,542 meters. The threshold height was good, and the threshold speed was also good at 144 knots.
However, the touchdown point was very long, using more than 50% of the available runway. The touchdown speed was a little fast at 143 knots, but the touchdown rate was good at -155 feet per minute. The runway touchdown position was significantly misaligned by 28.8 meters from the centerline. The local weather conditions at the time of landing were a temperature of 21 degrees Celsius and a wind speed of 21 knots at 350 degrees, with a crosswind component of 21 knots and a headwind component of 4 knots.
The total flight distance was 412 nautical miles, and the flight took 74 minutes to complete. The aircraft used 3,550 kilograms of fuel during the flight.
The Airbus A321 aircraft successfully landed on runway 27 at RCKH Kaohsiung International Airport, but the landing was not without some notable issues. The final approach was initiated from the east, heading 272.0° at a distance of 4 nautical miles and an altitude of 1,774 feet above ground level. The aircraft touched down on the runway, but unfortunately, it used more than 50% of the available runway, indicating a longer than ideal touchdown point.
The touchdown speed of 143 knots was slightly faster than the recommended threshold speed of 144 knots, which could have contributed to the longer than desired touchdown point. However, the touchdown rate of -155 feet per minute was within the acceptable range, indicating a relatively smooth and controlled descent. The runway touchdown position was significantly misaligned by 28.8 meters from the centerline, which could pose a challenge for the aircraft's braking performance and overall safety.
The local weather conditions at the time of the landing were relatively calm, with a temperature of 21°C and a wind speed of 21 knots from a direction of 350°. The crosswind component was 21 knots, while the headwind component was a relatively minor 4 knots. These conditions were not particularly challenging, but they may have contributed to the aircraft's misaligned touchdown position.
Overall, while the landing was successful, there were some notable issues that need to be addressed to improve the aircraft's performance and safety. The longer than ideal touchdown point and the misaligned touchdown position are areas that require attention to ensure a more controlled and efficient landing.
