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 3,601 m runway, to the same scale as the side view.
The 502 m 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 5 minutes and covered 2 nautical miles. From WIMM Kualanamu International Airport, the aircraft took off from runway 23, with a takeoff distance of 1,374 meters, or 37% of the runway length. The liftoff speed was 166 knots, and the local weather conditions were a temperature of 28°C and winds of 8 knots at 260 degrees.
As the aircraft climbed, it started its enroute climb 2 miles southwest of WIMM Kualanamu International Airport, rising from 1,101 feet above sea level to 36,417 feet above sea level. This climb of 35,316 feet took 18 minutes and covered 112 nautical miles.
Following the climb, the aircraft entered a level cruise phase 19 miles east of WW76 Rantau Prapat/Padang Halaban, and it remained in this phase for 77 minutes, covering 585 nautical miles. The aircraft then began its enroute descent 39 miles north of WIHG Pulau Panjang Airport Timurjaya, and it descended from 36,404 feet above sea level to 2,206 feet above sea level. This descent of 34,198 feet took 15 minutes and covered 71 nautical miles.
The aircraft then entered another level cruise phase 4 miles northeast of Jakarta, lasting only 3 minutes and covering 6 nautical miles. Following this brief cruise, the aircraft began its final descent 8 miles north of Jakarta and descended from 2,149 feet above sea level to 804 feet above sea level. This descent of 1,345 feet took only 2 minutes and covered 5 nautical miles.
Upon approaching runway 25R at WIII Soekarno-Hatta International Airport, the aircraft performed a go-around at 755 feet above sea level. However, it eventually landed on the runway, with a touchdown speed of 128 knots and a touchdown rate of -327 feet per minute. Unfortunately, the touchdown point was 94 meters beyond the touchdown zone, and the runway touchdown position was excessively misaligned by 34.8 meters from the centerline.
The local weather conditions at the time of landing were a temperature of 26°C and winds of 5 knots at 260 degrees. The crosswind was 1 knot, and the headwind was 4 knots. With a total landing distance of 917 meters, or 25% of the runway length, the aircraft then taxied to the parking area, taking 3 minutes and covering less than 1 nautical mile.
In total, the flight distance was 786 nautical miles, taking 125 minutes, and the aircraft used 4,740 kilograms of fuel.
The Boeing 737-MAX8 aircraft successfully landed on runway 25R at WIII Soekarno-Hatta International Airport, achieving an overall score of 81.5%. The final approach to the runway was initiated from the east, with a heading of 248.0° at a distance of 3 nautical miles and an altitude of 771 feet above ground level (agl). The aircraft successfully touched down on the runway, with a touchdown speed of 128 kt, which was within the acceptable range.
However, there were some areas of concern during the landing. The threshold speed was slightly below the target speed of 135 kt, which may indicate a slight delay in the aircraft's descent. Additionally, the touchdown point was 94 meters beyond the touchdown zone, which may indicate a slight over-shooting of the intended landing spot. The touchdown rate was firm at -327 fpm, which is within the acceptable range.
One of the major issues with this landing was the runway alignment. The aircraft touched down 34.8 meters off-centerline, which is a significant deviation from the centerline. This misalignment continued during the rollout, with the aircraft being 33.9 meters off-centerline. This may indicate a problem with the aircraft's navigation or control systems.
The local weather conditions at the time of the landing were favorable, with a temperature of 26°C and a wind speed of 5 kt from 260°. The crosswind was minimal at 1 kt, and the headwind was 4 kt, which may have contributed to the aircraft's misalignment during the rollout.
Overall, while the landing was successful, there are some areas that need improvement, particularly with regards to the aircraft's navigation and control systems. The pilots will need to work on maintaining a more accurate centerline alignment during the rollout to ensure a safe and efficient landing.
