MY FS FLIGHTS
Flight Score
Arrival
Fly a steeper descent on final so you cross the threshold at 50 ft agl instead of 73 ft agl.
What happened: The aircraft crossed the threshold at 73 ft agl against a 50 ft agl target, well above the normal profile. The touchdown point was also long at 899 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.
Even a modest height error carries straight through to the touchdown. Geometry alone says that crossing the threshold 10 feet high on a 3° path moves your touchdown roughly 190 feet further down the runway before the flare adds anything.

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 2,510 m of the approach.
Plan view — the first 2,510 m of the 3,758 m runway, to the same scale as the side view.
Touched down 899 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
Departing from Bandaranaike International Colombo Airport, the Boeing 777-300 began its journey by taxiing from the parking area to the runway, a process that took 6 minutes and covered a distance of 2 nautical miles. As it reached the runway threshold, the aircraft initiated its departure roll on runway 04, accelerating to a liftoff speed of 161 knots. The takeoff distance of 1,103 meters, which accounted for 33% of the runway, was within the expected parameters.
As the aircraft climbed out of Colombo, it began its enroute climb, reaching an altitude of 5,012 feet above sea level in just 2 minutes, covering a distance of 8 nautical miles. The climb continued in stages, with the aircraft reaching a cruising altitude of 36,652 feet above sea level after a 16-minute climb from 5,133 feet. The level cruise phase that followed lasted for 120 minutes, during which the aircraft covered a distance of 912 nautical miles. As the aircraft approached its destination, it began its descent, reducing its altitude from 36,999 feet to 1,338 feet in 26 minutes, covering a distance of 156 nautical miles.
The final approach to runway 23 at Kualanamu International Airport was initiated from the north-east, with the aircraft aligning itself with the runway at a height of 1,302 feet above ground level. The landing was executed with a threshold speed of 147 knots, but the touchdown speed of 142 knots was slightly above the target. The touchdown point was 482 meters beyond the touchdown zone, and the runway touchdown position was slightly misaligned by 4.5 meters from the centerline. The total landing distance of 2,429 meters, which accounted for 65% of the runway, was within the expected parameters. Following the landing, the aircraft taxied to the parking area, a process that took 3 minutes and covered a distance of less than 1 nautical mile. The total flight distance of 1,207 nautical miles was completed in 175 minutes, with the aircraft consuming 20,723 kilograms of fuel.
The Boeing 777-300 touched down on runway 23 at WIMM Kualanamu International Airport, having approached from the north east at a heading of 225.0°. The aircraft was 4 nautical miles from the threshold and at an altitude of 1,302 feet above ground level. The approach quality was satisfactory, with a threshold speed of 147 knots, which was within the acceptable range. However, the threshold height at 73 feet above ground level was higher than the target, indicating a slight deviation from the ideal approach path.
The touchdown point was located 482 meters beyond the touchdown zone, and the aircraft touched down at a speed of 142 knots, which was slightly faster than the recommended rate. The touchdown rate of -279 feet per minute was fair, but not ideal. The runway touchdown position was slightly misaligned from the centreline by 4.5 meters, which may have been due to a slight deviation in the approach path. The local weather conditions were favorable, with a temperature of 24°C and a light wind of 3 knots from 350°, resulting in a negligible crosswind and tailwind component.
The total landing distance of 2,429 meters was 65% of the runway length, which was acceptable. The runway rollout alignment was very good, indicating that the aircraft was well under control during the rollout phase. Overall, the landing performance was satisfactory, with a score of 87.8%. While there were some minor deviations from the ideal approach and touchdown characteristics, the aircraft was well-handled throughout the landing sequence.
