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. They are the approach's score: the checks passed out of the checks that ran.
The approach, gate by gate
Side view — the last 1,807 m of the approach.
Plan view — the first 1,807 m of the 2,745 m runway, to the same scale as the side view.
Touched down 671 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Boeing 737-800 taxied from the parking area to runway 28L at KSFO, a movement that required 21 minutes and covered 4 nm.
During the departure roll on runway 28L, the aircraft accelerated over a distance of 1,574 m, representing 47 % of the runway, and lifted off at 159 kt. Local weather at the time was temperature 20 °C, wind 14 kt at 280 °, with a cross-wind component of 4 kt and a head-wind component of 13 kt.
The initial climb began overhead San Bruno, climbing from 990 ft asl to 34,983 ft asl, an increase of 33,993 ft achieved in 25 minutes while covering 178 nm.
Level cruise commenced 6 miles north of the 2CN4 Wonderful Pistachios waypoint and continued for 60 minutes, during which 487 nm were flown.
A second climb segment started 9 miles south-west of KORI Oracle Airport, rising from 35,030 ft asl to 36,999 ft asl, an increase of 1,968 ft in 3 minutes and covering 25 nm.
Subsequent cruise began 7 miles south-east of San Manuel and lasted 70 minutes, encompassing 544 nm of flight.
Descent commenced 8 miles north-east of XA92 Herd Ranch Airport, descending from 36,997 ft asl to 1,835 ft asl, a loss of 35,162 ft in 24 minutes while covering 135 nm.
On final approach to runway 18L at KAUS, the aircraft descended from 1,367 ft agl to 114 ft agl in 98 seconds and was scored on the stabilisation gates.
Landing on runway 18L at KAUS was executed with a runway length of 2,745 m; the threshold height at 59 ft agl was slightly above target and the threshold speed was 145 kt. Touchdown occurred 257 m beyond the touchdown zone at a speed of 140 kt, with a touchdown rate of minus 220 fpm and very good runway-touchdown alignment. Local temperature was 23 °C.
The rollout covered a total landing distance of 1,729 m, representing 63 % of the runway, and the runway-rollout alignment was perfect.
The aircraft taxied from the runway to the parking area in 12 minutes, traveling 2 nm.
In total, the flight covered 1,382 nm, took 215 minutes, and consumed 8,546 kg of fuel.
The Boeing 737-800 approached runway 18L at KAUS Austin Bergstrom International Airport in a stabilised configuration at the 1,000 ft gate, with gear, flaps, sink rate, glideslope, centreline and speed all within limits, and the approach was scored on the stabilisation gates. The aircraft descended from 1,367 ft agl to 114 ft agl in 98 seconds before the flare.
At threshold the height of 59 ft agl was slightly above target and the threshold speed of 145 kt was good. Touchdown occurred 257 m beyond the touchdown zone with a speed of 140 kt, also judged good, and the touchdown rate was fair at minus 220 fpm. Runway touchdown alignment was very good.
The total landing distance measured 1,729 m, representing 63 % of the 2,745 m runway, and the touchdown was completed within the expected parameters.
Runway rollout alignment was perfect throughout the deceleration phase.
Minor refinements should focus on achieving the exact target threshold height and reducing the descent rate to obtain a smoother touchdown, which will further improve the already high score of 97.7 %.
