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 10 m off the runway centreline.
Watch for: Watch runway alignment against the centreline, correcting with small rudder inputs.
See Departure Roll
Arrival
Track the centreline through touchdown using small rudder corrections against a point at the far end of the runway.
What happened: The aircraft touched down off the centreline at 9.3 m, and drifting off centreline at touchdown usually carries through into the rollout, as it did here with alignment reaching 15 m.
Watch for: Watch runway centreline position, keeping deviation inside the limit through touchdown and rollout.
Ground control varies with speed, full authority at walking pace, progressively reducing as groundspeed rises. The aircraft becomes twitchy at any speed, every small pedal input swings the nose, which can encourage large-amplitude leg inputs that no real aircraft would accept.

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 seven 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 1,889 m of the approach.
Plan view — the first 1,889 m of the 2,740 m runway, to the same scale as the side view.
The 452 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The Boeing 777-300ER taxied from the parking area to runway 28L at KSFO, a movement that required 17 minutes and covered 2 nm.
During the departure roll on runway 28L, the aircraft used 2,132 m of runway, representing 63 % of the available length, and lifted off at 169 kt; local conditions were 15 °C with a wind of 4 kt from 246°, including a 3 kt cross-wind and a 2 kt head-wind.
Climb commenced over San Bruno, rising from 1,026 ft asl to 34,996 ft asl-a gain of 33,970 ft-over 16 minutes while traversing 105 nm.
The first cruise segment began 1 mile north-east of Dos Palos Y and continued for 141 minutes, covering 1,195 nm.
Descent started 2 miles north-west of Florence, descending from 34,988 ft asl to 12,413 ft asl, a loss of 22,575 ft in 12 minutes and 82 nm.
A brief cruise followed 4 miles north-east of College Station, lasting 2 minutes and spanning 8 nm.
The next descent began 8 miles south of 3TE0 K Ranch Airport Iola, dropping from 11,573 ft asl to 9,015 ft asl, a decrease of 2,558 ft in 2 minutes over 9 nm.
A subsequent cruise segment originated 9 miles north-east of TS87 Bridle Ridge Airport Navasota, persisting for 5 minutes and covering 24 nm.
Descent then proceeded 8 miles north-east of the same airport, falling from 8,986 ft asl to 6,032 ft asl, a loss of 2,954 ft in 3 minutes while traveling 14 nm.
The following cruise started 4 miles north of TS75 Mitchell Number One Airport Sanderson, lasting 8 minutes and encompassing 32 nm.
Descent continued 2 miles north of Spring, decreasing altitude from 6,002 ft asl to 2,998 ft asl, a reduction of 3,004 ft in 3 minutes across 12 nm.
A short cruise then began 3 miles north of Atascocita, lasting 2 minutes and covering 5 nm.
The final descent segment started 4 miles north-east of Atascocita, descending from 2,985 ft asl to 1,309 ft asl, a loss of 1,676 ft in 3 minutes and 10 nm.
On final approach to runway 26R at KIAH, the aircraft descended from 1,248 ft agl to 39 ft agl in 94 seconds and was scored on the stabilisation gates.
Landing on runway 26R at KIAH, which is 2,740 m long, occurred with a threshold speed of 148 kt; touchdown was 50 m beyond the touchdown zone at 145 kt, with a touchdown rate of minus 255 fpm and very good alignment, while local weather reported 35 °C, wind 3 kt from 100°, a 1 kt cross-wind and a 3 kt tail-wind.
The rollout covered a total landing distance of 1,822 m, representing 66 % of the runway, and the aircraft’s centreline alignment was offset by 14.9 m.
Taxi-in to the parking area required 13 minutes and traversed 3 nm.
Overall, the flight covered 1,507 nm, lasted 227 minutes, and consumed 26,735 kg of fuel.
The Boeing 777-300ER approached runway 26R at KIAH in a stabilised configuration at the 1,000 ft gate, with gear, flaps, sink rate, glideslope, centreline and speed all within limits. The aircraft descended from 1,248 ft AGL to 39 ft AGL in 94 seconds and was scored on the stabilisation gates.
During the threshold and flare phase the threshold height was good and the threshold speed was good at 148 kt. The aircraft touched down 50 m beyond the touchdown zone, with a touchdown speed of 145 kt that was a little fast and a touchdown rate that was fair at minus 255 fpm. Runway touchdown alignment was very good.
At touchdown the speed of 145 kt remained slightly above the optimum, the vertical rate was minus 255 fpm, and the aircraft maintained very good alignment with the runway centreline.
The rollout covered a total landing distance of 1,822 m, representing 66 % of the 2,740 m runway, and the aircraft finished slightly off centreline by 14.9 m.
Refine the flare to achieve a marginally lower touchdown speed and monitor centreline tracking during rollout to reduce the 14.9 m deviation, which will further improve the already strong 92.4 % score.
