Landing on runway XX at Incheon International Airport in the Boeing 777-300

Landing Score 62.64 %

Landing Summary

The Boeing 777-300 touched down on Runway 34L at Incheon International Airport with a smooth touchdown rate of -126 fpm, indicating a well-executed landing. The aircraft's touchdown speed of 130 kt was within acceptable limits, demonstrating good control and management of the approach. The descent from 34 ft agl to 0 ft agl was completed in 10 seconds, a relatively short period that suggests a stable and controlled approach.

Upon touchdown, the aircraft utilized more than 50% of the available runway, resulting in a long touchdown point. This may be attributed to the aircraft's weight and the prevailing wind conditions, which included a 13 kt crosswind and an 8 kt headwind. The local weather conditions, with a temperature of 17 °C and a wind speed of 15 kt at 260 °, also played a role in the landing's characteristics. Despite these factors, the pilot maintained control and executed a safe touchdown.

The landing rollout was completed at an altitude of 22 ft asl, with a distance of 1,067 m. This indicates a relatively long rollout, which may be due to the aircraft's weight and the braking performance. Overall, the landing scored 62.6%, reflecting a good but not exceptional performance. The approach quality was satisfactory, with a stable and controlled descent, but the touchdown point was longer than desired.
