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 8,017 ft of the approach.
Plan view — the first 8,017 ft of the 10,998 ft runway, to the same scale as the side view.
Touched down 2,074 ft past the threshold — beyond the full-score zone. The 2.55 G arrival is the firm side of smooth.
The rest of the report
The flight began with a taxiing period from the parking to the runway, which took 25 minutes and covered a distance of 4 nautical miles. The aircraft, a Boeing B737-800, then departed from runway 27R at Hartsfield Jackson Atlanta International Airport, with a takeoff distance of 8,838 feet, which was 74% of the runway length. The liftoff speed was 150 knots.
As the aircraft climbed, it started at an altitude of 2,050 feet above sea level and reached a maximum altitude of 19,001 feet, an increase of 16,952 feet in just 8 minutes, covering a distance of 24 nautical miles. The enroute climb began 1 mile southwest of College Park, Georgia, and ended 1 mile northwest of the Lola Landing Airport in Conyers, Georgia.
Following the climb, the aircraft entered a level cruise phase, which lasted for 3 minutes and covered a distance of 31 nautical miles. The enroute descent started 3 miles east of Arcade, Georgia, and involved a descent from 19,006 feet to 2,216 feet, a decrease of 16,791 feet in 17 minutes, covering a distance of 75 nautical miles.
The final approach to runway 04 at Greenville Spartanburg International Airport was made from the southwest, with a heading of 33.0 degrees at an altitude of 1,256 feet above ground level, 4 nautical miles from the runway. The landing was made on a runway with a length of 10,998 feet, and the threshold height was well above the target, while the threshold speed was slightly below the target at 133 knots.
The touchdown point was 669 feet beyond the touchdown zone, with a touchdown speed of 134 knots, which was considered good. However, the touchdown rate was very heavy at -732 feet per minute. The runway touchdown position was misaligned by 36 feet from the centerline, and the runway rollout alignment was also misaligned by 94 feet from the centerline.
The taxiing period from the runway to the parking took 8 minutes and covered less than 1 nautical mile. The total flight distance was 143 nautical miles, and the flight duration was 47 minutes. The aircraft used a total of -1,708 pounds of fuel during the flight.
The Boeing B737-800 aircraft successfully landed at Greenville Spartanburg International Airport (KGSP) on runway 04. The final approach was initiated from the southwest, heading 33.0° at a distance of 4 nautical miles and an altitude of 1,256 feet above ground level (agl). The aircraft touched down on the runway, with a touchdown speed of 134 knots, which was within the target range.
However, the landing was not without some issues. The threshold height at 78 feet agl was significantly above the target, indicating that the aircraft was higher than expected when it reached the runway threshold. Additionally, the threshold speed was a little below the target at 133 knots, suggesting that the aircraft may have been slightly slow on approach.
The touchdown point was 669 feet beyond the touchdown zone, which is a significant deviation from the intended landing spot. This could be due to a variety of factors, including pilot error or issues with the aircraft's navigation system. The touchdown rate was also very heavy at -732 feet per minute (fpm), which is higher than the typical touchdown rate for a Boeing B737-800. This could indicate that the aircraft was experiencing a high rate of descent during the final approach.
Furthermore, the runway touchdown position was misaligned by 36 feet from the centreline, which could pose a risk to the aircraft's stability and control during the landing roll. The local weather conditions at the time of the landing were characterized by a temperature of 64°F, which is relatively mild and should not have had a significant impact on the aircraft's performance.
The total landing distance was 7,712 feet, which is 70% of the runway length. This is a relatively long landing distance, and it may indicate that the aircraft was experiencing some issues with its braking performance or that the pilots were not able to achieve the optimal touchdown speed. The runway rollout alignment was also misaligned by 94 feet from the centreline, which could pose a risk to the aircraft's stability and control during the landing roll.
Overall, while the Boeing B737-800 aircraft was able to land safely at KGSP, there were several issues with the landing that need to be addressed. These include the high threshold height, slow threshold speed, heavy touchdown rate, and misaligned touchdown and rollout positions.
