Landing on runway 09L at EGLL London Heathrow Airport in the Boeing 777-300

Landing Score 98.75 %

Landing Summary

The Boeing 777-300 aircraft successfully landed on runway 09L at EGLL London Heathrow Airport, achieving a high score of 98.8%. The final approach was conducted from the west, heading 90.0° at a distance of 4 nautical miles and an altitude of 1,252 feet above ground level (agl). The aircraft's approach to the runway was precise, with a good threshold height and a slightly above-target threshold speed of 147 knots.

Upon touchdown, the aircraft's performance was satisfactory, with a touchdown distance of 405 meters, which is within the acceptable range. However, the touchdown speed of 143 knots was slightly faster than the target speed, indicating that the pilots may have needed to apply more braking force to slow down the aircraft. The touchdown rate of -338 feet per minute (fpm) was firm, suggesting that the aircraft's wheels made contact with the runway with a moderate amount of force.

The runway touchdown alignment was excellent, indicating that the pilots maintained a stable and consistent approach path. The local weather conditions at the time of landing were mild, with a temperature of 7°C and a light wind of 6 knots from 140°. The crosswind component was 5 knots, while the headwind component was 4 knots, which is relatively minimal and should not have significantly impacted the landing.

The total landing distance of 1,780 meters was 50% of the runway length, which is a reasonable distance considering the aircraft's size and weight. The runway rollout alignment was perfect, indicating that the pilots maintained control of the aircraft during the rollout phase and brought it to a stop safely. Overall, the landing was successful, and the pilots demonstrated good skills and judgment in navigating the aircraft to a safe touchdown.
