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 1,524 m of the approach.
Plan view — the first 1,524 m of the 3,639 m runway, to the same scale as the side view.
The 256 m touchdown sits inside the full-score zone. The 2.81 G arrival is the firm side of smooth.
The rest of the report
The flight began with a departure roll from runway 25L at Hong Kong International Airport (VHHH). The Cessna Skyhawk took off with a takeoff distance of 843 meters, which is 23% of the runway length. The liftoff speed was 72 knots, and the local weather conditions were characterized by a temperature of 16 degrees Celsius and a wind speed of 1 knot from 270 degrees.
As the aircraft climbed away from the airport, it began its enroute climb 1 mile southwest of VHHH. The climb started from an altitude of 1,036 feet above sea level and reached 3,222 feet in just 5 minutes, covering a distance of 4 nautical miles. This rapid ascent was achieved by increasing the altitude by 2,186 feet.
Following the climb, the aircraft entered a level cruise phase, which lasted for 18 minutes and covered a distance of 3 nautical miles. This cruise phase took place 2 miles northeast of Tung Chung, another location in Hong Kong.
As the aircraft began its enroute descent, it started from an altitude of 2,923 feet above sea level and descended to 1,814 feet in just 2 minutes, covering a distance of 4 nautical miles. This descent phase took place 4 miles southeast of Tuen Mun, another location in Hong Kong.
The final approach to runway 25L at VHHH was made from the east, with the aircraft heading 248.0 degrees at 1 nautical mile from the airport. The aircraft was at an altitude of 1,760 feet above ground level at this point.
The landing on runway 25L was not entirely smooth, with the touchdown point being 100 meters beyond the touchdown zone. The touchdown speed was 96 knots, which is excessively fast, and the touchdown rate was very heavy at -1,472 feet per minute. Additionally, the runway touchdown position was significantly misaligned by 20.7 meters from the centerline.
The total landing distance was 685 meters, which is 19% of the runway length. The runway rollout alignment was also misaligned by 21.7 meters from the centerline. After landing, the aircraft taxied to the parking area, taking 4 minutes and covering less than 1 nautical mile.
The total flight distance was 14 nautical miles, and the flight duration was 33 minutes. The aircraft used 13 kilograms of fuel during the flight.
The Cessna Skyhawk aircraft has successfully landed at VHHH Hong Kong International Airport, but the landing was not without its issues. The final approach to runway 25L from the east was initiated at a heading of 248.0°, with the aircraft at 1 nautical mile and 1,760 feet above ground level (agl). However, the landing was not executed perfectly, with several parameters exceeding the target values.
One of the main concerns was the excessive height of the threshold at 137 feet agl, which was significantly above the target value. This could have been due to a number of factors, including an incorrect approach path or a failure to maintain the correct descent rate. Additionally, the threshold speed of 100 knots was also excessively high, indicating that the aircraft may have been descending too quickly or that the pilot may have been unable to maintain the correct airspeed.
The touchdown point was 100 meters beyond the touchdown zone, which is a significant deviation from the intended landing spot. This could have been due to a number of factors, including a failure to maintain the correct heading or a lack of control during the final stages of the approach. The touchdown speed of 96 knots was also excessively fast, indicating that the pilot may have been unable to maintain the correct airspeed or that the aircraft may have been descending too quickly.
The touchdown rate of -1,472 feet per minute (fpm) was also very heavy, indicating that the aircraft may have been experiencing a high rate of descent during the final stages of the approach. This could have been due to a number of factors, including a failure to maintain the correct descent rate or a lack of control during the final stages of the approach.
The runway touchdown position was significantly misaligned by 20.7 meters from the centerline, which could have been due to a number of factors, including a failure to maintain the correct heading or a lack of control during the final stages of the approach. The runway rollout alignment was also misaligned by 21.7 meters from the centerline, which could have been due to a number of factors, including a failure to maintain the correct heading or a lack of control during the final stages of the approach.
The total landing distance of 685 meters was 19% of the runway length, which is a relatively short landing distance. However, the landing was not without its issues, and the pilot may need to review their approach and landing techniques to improve their performance.
The local weather conditions at the time of the landing were relatively calm, with a temperature of 16°C and a wind speed of 1 knot from 269°. The crosswind was negligible, and the headwind was 1 knot, which would have had a minimal impact on the aircraft's performance during the approach and landing.
