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.

Two stabilised approach gates, each with six checks at 1,000 ft and 500 ft above the runway.
The approach, gate by gate
Side view — the last 5,942 ft of the approach.
Plan view — the first 5,942 ft of the 12,870 ft runway, to the same scale as the side view.
Touched down 2,059 ft past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Airbus A350-900 taxied from the parking area to runway 06 at DNKN Mallam Aminu International Airport in 5 minutes, covering less than 1 nm.
During the departure roll on runway 06, the aircraft used 5,710 ft of runway, representing 51 % of the available length, and lifted off at 154 kt. Ambient conditions were 97 °F with a wind of 2 kt from 129°, including a 2 kt crosswind component and a 1 kt headwind.
Climb commenced overhead the departure airport, ascending from 2,500 ft asl to 37,396 ft asl, an increase of 34,896 ft achieved in 27 minutes while covering 182 nm.
The first en-route cruise began 19 mi north-west of DN50 Shiroro Airport in Niger State and persisted for 22 minutes, during which 173 nm were flown.
Descent started 14 mi south-west of DNIL Ilorin International Airport in Kwara State, descending from 38,000 ft asl to 3,913 ft asl, a loss of 34,087 ft in 17 minutes and covering 102 nm.
A subsequent cruise segment originated 2 mi south-west of Abeokuta in Ogun State, lasting 7 minutes and spanning 23 nm.
The next descent began 8 mi south-east of Ifo, also in Ogun State, dropping from 3,128 ft asl to 1,410 ft asl, a decrease of 1,718 ft in 2 minutes over a distance of 5 nm.
Final approach to runway 18R at DNMM Murtala Muhammed International Airport was executed from the north, on a heading of 179.0° at 4 nm and 1,348 ft agl.
Landing on runway 18R, which is 12,870 ft long, occurred with a threshold speed of 135 kt; the aircraft touched down 670 ft beyond the touchdown zone at 131 kt, with a touchdown rate of minus 158 fpm and a lateral deviation of 16 ft from the centreline. Weather at the time was 77 °F with a wind of 1 kt from 0°, no crosswind and a 1 kt tailwind component.
The rollout covered 5,653 ft, representing 44 % of the runway, and alignment during the roll was reported as very good.
After exiting the runway, the aircraft taxied to the parking area in 5 minutes, traversing 1 nm.
In total, the flight covered 494 nm, required 86 minutes of airborne time, and consumed 18,828 lb of fuel.
The final approach to runway 18R at DNMM Murtala Muhammed International Airport was flown from the north on a heading of 179.0° at 4 nm and 1,348 ft agl. The approach was assessed as stabilised at the 1,000 ft gate, with gear, flaps, sink rate, glideslope and centreline all within limits, and the local weather was 77 °F with a wind of 1 kt from 0°, crosswind 0 kt and tailwind 1 kt.
During the threshold and flare segment the aircraft presented a good threshold height and a good threshold speed of 135 kt.
Touchdown occurred 670 ft beyond the touchdown zone with a touchdown speed of 131 kt, noted as a little fast, and a touchdown rate of -158 fpm. The runway touchdown position was slightly misaligned by 16 ft from the centreline.
The total landing distance was 5,653 ft, representing 44 % of the 12,870-ft runway, and the runway rollout alignment was very good.
To refine the already strong performance, a modest reduction in touchdown speed would bring the aircraft closer to the target VREF, and a slight adjustment of the flare path could improve centreline alignment to within a few feet of the runway centre.
