MY FS FLIGHTS
Flight Score
Departure
Make small rudder corrections against a point at the far end to hold the centreline.
What happened: During the ground roll you drifted 30 m off the runway centreline.
Watch for: Watch runway alignment against the centreline, correcting with small rudder inputs.
See Departure Roll
Arrival
Fly a steeper descent on final so you cross the threshold at 50 ft agl instead of 88 ft agl.
What happened: The aircraft crossed the threshold at 88 ft agl against a 50 ft agl target, well above the normal profile. The touchdown point was also long at 1,302 m against a 457 m target, a pattern often seen after high threshold crossings.
Watch for: Radio altimeter against the 50 ft threshold crossing target on short final.
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.
Two stabilised approach gates, each with six checks, where the approach path is 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 2,029 m of the approach.
Plan view — the first 2,029 m of the 3,530 m runway, to the same scale as the side view.
Touched down 1,302 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The aircraft taxied from the parking area to runway 19L at KSFO, a taxi-out that lasted 17 minutes and covered 2 nm.
During the departure roll on runway 19L, the B772 accelerated for a takeoff distance of 2,010 m, representing 76 % of the runway length, and rotated at 144 kt. Local weather at the time was 15 °C with a wind of 6 kt from 267°, including a 5 kt crosswind and a 3 kt headwind.
The initial climb began overhead Millbrae, climbing from 712 ft asl to 36,597 ft asl, an increase of 35,884 ft achieved in 28 minutes while covering 196 nm.
Level cruise commenced 3 miles east of Hawthorne, Nevada, and continued for 71 minutes, during which the aircraft flew 602 nm.
A second climb segment started 16 miles northwest of 25CO Crystal Lakes Airport, Colorado, climbing from 37,235 ft asl to 38,489 ft asl, a gain of 1,253 ft in 3 minutes and covering 27 nm.
The next cruise phase began 15 miles southeast of WY61 Gas Hills Airstrip, Wyoming, lasting 93 minutes and encompassing 758 nm.
Descent began 1 mile northeast of Kaneville, Illinois, descending from 39,011 ft asl to 3,082 ft asl, a loss of 35,930 ft in 18 minutes while covering 114 nm.
A brief cruise segment over Carol Stream, Illinois, lasted 13 minutes and spanned 47 nm.
The following descent started 5 miles northeast of Evanston, Illinois, dropping from 3,031 ft asl to 2,540 ft asl, a decrease of 491 ft in 2 minutes over 4 nm.
A short cruise then proceeded 2 miles northeast of Rogers Park, Illinois, lasting 4 minutes and covering 9 nm.
On final approach to runway 27C at KORD, the aircraft descended from 1,271 ft agl to 85 ft agl in 110 seconds, achieving the required stabilisation gates.
Landing on runway 27C at KORD was performed with a runway length of 3,530 m; the threshold height at 88 ft agl was above target, while the threshold speed was 138 kt. Touchdown occurred 878 m beyond the touchdown zone at a speed of 129 kt, with a firm touchdown rate of minus 326 fpm and a lateral deviation of 13.6 m from the centreline. Local weather reported 18 °C with a wind of 7 kt from 65°, including a 3 kt crosswind and a 6 kt tailwind. Total landing distance was 1,940 m, representing 55 % of the runway, and rollout alignment was off by 13.7 m from centreline.
The aircraft taxied from the runway to the parking area in 12 minutes, covering a further 2 nm.
In total, the flight covered 1,768 nm, required 265 minutes of airborne time, and consumed 30,662 kg of fuel.
The approach to runway 18R at EHAM was assessed as stabilised at the 1,000 ft gate, with gear, flaps, sink rate, glideslope, centreline and speed all within limits. The aircraft descended from 1,351 ft AGL to 88 ft AGL in 107 seconds on a final approach that featured a temperature of 17 °C, wind 2 kt from 150°, a 1 kt cross-wind component and a 2 kt head-wind component.
At threshold the speed was recorded as good at 136 kt and the threshold height was good. The aircraft touched down 364 m down the runway, with a touchdown speed a little fast at 136 kt and a hard touchdown rate of minus 466 fpm, while runway touchdown alignment was very good.
Touchdown occurred 364 m from the threshold with the noted speed and rate, maintaining the very good alignment achieved during the flare.
Rollout covered a total landing distance of 1,757 m, representing 50 % of the 3,526 m runway, and the aircraft finished slightly misaligned by 9.7 m from the centreline.
Minor refinements are advised: reduce touchdown speed slightly toward the target VREF to help soften the hard rate of minus 466 fpm, and fine-tune flare timing to achieve a gentler touchdown while preserving the excellent alignment already demonstrated.
