Top opportunity

Shorten the long landing

Arrival Touchdown

Ground effect becomes significant below about one wingspan of height. A Cessna 172, with a 36 ft span, enters ground effect at flare height - the float it feels in the hold-off is ground effect arriving on cue. An A320, with a span around 117 ft, has been in ground effect since before the threshold and there is no sudden cushion to feel, only a gradual reduction in induced drag that lengthens any float you allow.

Flight narrative

A Boeing 777-300 departed from Logan International Airport (KBOS) in Boston, Massachusetts, on runway 33L. The aircraft accelerated down the 2,199-meter runway, utilizing 78% of its length, and lifted off at a speed of 187 knots. The local weather conditions at the time of departure featured a temperature of 12°C, with a 19-knot headwind and a 2-knot crosswind.

As the aircraft climbed to its initial cruising altitude, it passed over Chelsea, Massachusetts, and continued to ascend to 28,387 feet above sea level. The enroute climb phase was followed by a level cruise, which lasted for 204 minutes and covered a distance of 1,688 nautical miles. The aircraft made several subsequent climbs and level cruises, with notable increases in altitude at Doris Lake Hope Bay, Nunavut, and Nome, Alaska. The final level cruise phase took place over the Bering Sea, before the aircraft began its descent towards Incheon International Airport in South Korea. The descent phase was characterized by a series of gradual reductions in altitude, with the aircraft eventually touching down on the runway at a speed of 130 knots and a rate of -126 feet per minute.

The landing rollout was smooth, with the aircraft coming to a stop at an altitude of 22 feet above sea level after traveling 1,067 meters down the runway. The total flight distance was 6,578 nautical miles, and the aircraft used 128,964 kilograms of fuel during the 903-minute journey. The landing was completed in a local weather environment featuring a temperature of 17°C, with a 15-knot headwind and a 13-knot crosswind.

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.
