Flight narrative

Departing from London Heathrow Airport, the Boeing 777-200ER began its journey on runway 27R, taking off with a liftoff speed of 163 kt. The aircraft's takeoff distance of 1,150 m, covering 32% of the runway, was within the expected parameters. The local weather conditions at the time of departure featured a temperature of 15 °C and a headwind of 26 kt, which contributed to the aircraft's efficient takeoff.

As the aircraft climbed to its initial cruising altitude, it passed over various landmarks in the UK, including Harmondsworth and Ascot. The enroute climb phase saw the aircraft ascend to 34,447 ft asl, a significant increase of 28,683 ft in 18 minutes. The aircraft then entered a prolonged level cruise phase, lasting 241 minutes, during which it covered a distance of 1,697 nm. This was followed by a series of climbs and descents, with the aircraft adjusting its altitude to optimize fuel efficiency and navigate through various weather conditions. The final approach to Logan International Airport's runway 04R was initiated from the south, with the aircraft touching down at a speed of 135 kt and a touchdown distance of 426 m.

The landing was deemed successful, with a touchdown rate of -301 fpm and a runway touchdown position that was slightly misaligned from the centreline. The total landing distance of 1,357 m, covering 58% of the runway, was within the expected parameters. The aircraft's total flight distance of 2,876 nm was completed in 446 minutes, with a fuel consumption of 49,509 kg.

Landing Summary

The Boeing 777-200ER touched down on runway 04R at KBOS Logan International Airport with a good threshold height, allowing the crew to maintain a stable approach profile. The final approach was initiated from the south, heading 20.0° at 4 nm and 1,267 ft above ground level. The aircraft's speed was well-managed, with a threshold speed of 138 kt, which was within the acceptable range. The touchdown distance of 426 m was also satisfactory, indicating a smooth and controlled descent.

Upon touchdown, the aircraft's speed was 135 kt, which was within the recommended range for a firm touchdown. The touchdown rate of -301 fpm was firm, but not excessively hard, suggesting that the crew had maintained good control of the aircraft's descent. However, the runway touchdown position was slightly misaligned by 5.9 m from the centreline, which may have been due to a slight deviation in the approach path. The local weather conditions, with a temperature of 7 °C and winds of 8 kt at 140°, were not particularly challenging.

The total landing distance of 1,357 m was 58% of the runway length, which was within the acceptable range. The runway rollout alignment was also slightly misaligned by 7.8 m from the centreline, which may have been due to a slight deviation in the aircraft's direction during the rollout phase. Despite these minor deviations, the overall landing performance was satisfactory, with a score of 96.8%. The crew's ability to maintain a stable approach profile and control the aircraft's descent was commendable, and the landing was completed safely and efficiently.
