Maintain the centreline
A small uncorrected heading error at 40 knots becomes a metre of offset per second by 100 knots, noticed only at rotation, producing a crabbed liftoff. Root cause is nearly always eyes on the tape instead of the far end of the runway. Small heading changes displace a distant point visibly long before the nearby centreline stripes look wrong.

Two stabilised approach gates, each with five checks, where the approach path is 1,000 ft and 500 ft above the runway.
The approach, gate by gate
Side view — the last 1,967 m of the approach.
Plan view — the first 1,967 m of the 2,731 m runway, to the same scale as the side view.
Touched down 546 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Boeing 777-300 taxied from the parking area to runway 16 at LSZH Zürich Airport in less than 1 minute, covering less than 1 nm.
The aircraft commenced its departure roll on runway 16, accelerating to a liftoff speed of 187 kt and using a takeoff distance of 2,400 m, which represented 65 % of the runway. Local weather was 35 °C temperature, wind 1 kt from 179°, with a headwind component of 1 kt and no cross-wind.
Climb began overhead Opfikon, rising from 2,383 ft asl to 33,997 ft asl, an altitude gain of 31,614 ft achieved in 18 minutes while covering 125 nm.
Level cruise commenced 1 nm north-west of Oberderdingen, Germany, and continued for 188 minutes, during which the aircraft flew 1,504 nm.
A subsequent climb segment started at latitude 52.5508618, longitude -30.5612812, increasing altitude from 33,997 ft asl to 36,014 ft asl, a gain of 2,016 ft in 3 minutes over a distance of 28 nm.
The next cruise phase began at latitude 52.6175088, longitude -31.3482499 and lasted 235 minutes, covering 1,771 nm.
Descent commenced 1 nm north-west of North Seekonk, Massachusetts, descending from 35,994 ft asl to 9,976 ft asl, a loss of 26,017 ft in 16 minutes across 100 nm.
A brief cruise segment followed 1 nm south of Yaphank, New York, lasting 2 minutes and covering 9 nm.
The final descent began 2 mi south-east of Bayport, New York, dropping from 9,919 ft asl to 1,246 ft asl, a decrease of 8,673 ft in 9 minutes over 34 nm.
The aircraft entered final approach to runway 31R at KJFK John F Kennedy International Airport from the south-east, on a heading of 301.0°, at 4 nm and 1,210 ft agl.
Touchdown occurred on runway 31R, whose length is 2,729 m, with a threshold speed of 146 kt. The aircraft touched down 139 m beyond the touchdown zone at a speed of 141 kt, a vertical rate of minus 113 fpm, and was laterally offset by 4.4 m from the centreline. Local conditions were 29 °C temperature, wind 4 kt from 200°, with a 4 kt cross-wind and a 1
The Boeing 777-300 entered the final approach to runway 31R at KJFK from the south-east, tracking a heading of 301.0° at 4 nm and 1,210 ft agl. Local conditions were 29 °C with wind 4 kt from 200°, a 4 kt crosswind component and a 1 kt tailwind component.
At threshold the aircraft maintained a good height and a good threshold speed of 146 kt, setting up a stable flare.
Touchdown occurred 139 m beyond the designated touchdown zone with a speed of 141 kt that was a little fast; the vertical rate was smooth at minus 113 fpm and the touchdown point was slightly misaligned by 4.4 m from the centreline.
The rollout covered a total landing distance of 1,896 m, representing 69 % of the 2,729 m runway, and the runway alignment during rollout was very good.
With a final score of 97.5 % the landing was strong overall; reducing touchdown speed to the target range and correcting the 4.4 m lateral offset will tighten performance further.
