Landing on runway 22L at KBOS Logan International Airport in the Boeing 777-300

Landing Score 80.37 %

Landing Summary

The Boeing 777-300 aircraft successfully landed at KBOS Logan International Airport, but with some notable deviations from the ideal landing parameters. The aircraft was approaching the runway from the north, heading 200.0° at a distance of 4 nautical miles and an altitude of 1,280 feet above ground level (agl). The final approach was made to runway 22L, which has a length of 2,329 meters.

Upon landing, the aircraft touched down 435 meters beyond the touchdown zone, which is a significant deviation from the ideal touchdown point. The touchdown speed of 136 knots was within the acceptable range, indicating that the pilot had maintained control of the aircraft during the descent. However, the touchdown rate of -204 feet per minute (fpm) was only fair, suggesting that the aircraft may have experienced some deceleration issues during the landing.

The threshold height at 66 feet agl was above the target, indicating that the aircraft may have been slightly higher than desired when it reached the runway threshold. The threshold speed of 149 knots was also slightly above the target, which may have contributed to the aircraft's deviation from the ideal touchdown point.

The local weather conditions at the time of the landing were characterized by a temperature of 1°C and a wind speed of 10 knots from 220°. The crosswind component was minimal at 3 knots, while the headwind component was 9 knots. These conditions may have affected the aircraft's performance during the landing.

The total landing distance of 1,957 meters was 84% of the runway length, which is within the acceptable range. However, the runway touchdown position was misaligned by 9.9 meters from the centerline, and the runway rollout alignment was also slightly misaligned by 13.4 meters from the centerline. These deviations from the ideal alignment may have been caused by the pilot's response to the wind conditions or other factors.

Overall, the landing was successful, but with some notable deviations from the ideal parameters. The pilot's performance was good, but there is room for improvement in terms of touchdown point accuracy and touchdown rate.
