What went well

Straight touchdown — 11.4 ft off the centreline, no bounce
Rollout held the centreline — 1.2 ft off at taxi speed
Airborne in 4,630 ft — 42 % of the runway

What held you back

Arrival Touchdown — Touchdown rate was -345 fpm at 65 %, Touchdown distance was 2,351 ft at 72 %, −1.08 points
Arrival Landing — Threshold speed was well above target at 170 kt at 68 %, Flare profile at 71 %, −1.02 points
Arrival Approach — GPWS warning; 1,000 ft gate 100 %, 500 ft gate 86 %, −0.48 points

Next time

Departure

Start bringing the nose up as the speed reaches 165 kt, not after it.

What happened: You started the rotation at 187 kt, 22 kt past the 165 kt rotation speed.

Watch for: Airspeed indicator: 165 kt at rotation

See Departure Roll

Arrival

Reduce power earlier on final to bleed back to 143 kt well before the gate.

What happened: Approach was fast through the stabilisation gate, and the threshold was crossed at 169 kt against the 143 kt target. Carrying that extra speed in usually carries the touchdown long, which it did here at 2,351 ft against the 1,500 ft target.

Watch for: Airspeed indicator: 143 kt at the threshold

See Arrival ApproachArrival LandingArrival Touchdown

There are several things that can go wrong during the flare, carrying too much speed over the threshold, starting the flare at the wrong height and inconsistent flight control inputs, all contribute to a poor flare resulting in a hard touchdown or a float down the runway.

Flight narrative

Departing from London Heathrow Airport, the Boeing 777-300 began its journey by taxiing from the parking area to the runway, a process that took 20 minutes and covered a distance of 4 nautical miles. As it reached the runway, the aircraft started its departure roll on runway 09R, accelerating to a liftoff speed of 194 knots. The takeoff distance of 4,657 feet was 42% of the runway length, with a local temperature of 58°F and wind conditions of 5 knots at 59°, resulting in a 2-knot headwind.

As the aircraft climbed away from London, it began its enroute climb, reaching an altitude of 6,209 feet in just 2 minutes, covering a distance of 9 nautical miles. The climb continued in stages, with the aircraft reaching a cruise altitude of 33,637 feet over the English countryside and later 35,921 feet over the Irish Sea. The enroute level cruise phases lasted for various periods, with the longest lasting 31 minutes and covering 1,816 nautical miles. The aircraft then began its descent, reducing its altitude from 38,007 feet to 1,320 feet in 20 minutes, before making its final approach to runway 22L at Logan International Airport.

The Boeing 777-300 touched down on runway 22L, with a touchdown speed of 163 knots and a touchdown rate of -285 feet per minute. The touchdown point was 1,007 feet beyond the touchdown zone, and the runway touchdown position was slightly misaligned by 18 feet from the centerline. The total landing distance was 5,675 feet, 74% of the runway length. After a short taxiing period, the aircraft came to a stop, having completed a total flight distance of 2,911 nautical miles, using 105,999 pounds of fuel and taking a total of 159 minutes.

Landing Score 88.77 %
Landing Summary

The Boeing 777-300 touched down on runway 22L at KBOS Logan International Airport, marking a satisfactory conclusion to the approach from the north. The aircraft's descent was well-managed, with a good threshold height achieved. However, the threshold speed was slightly above the optimal range, reaching 170 kt. This may have contributed to the slightly fast touchdown speed of 163 kt.

Upon touchdown, the aircraft's rate of descent was fair at -285 fpm, but the touchdown point was located 1,007 ft beyond the designated touchdown zone. This deviation was likely due to the slightly high touchdown speed. Furthermore, the runway touchdown position was slightly misaligned by 18 ft from the centreline, indicating a minor deviation from the intended path. The local weather conditions, with a temperature of 70 °F and a 7 kt headwind, did not appear to significantly impact the landing.

The total landing distance of 5,675 ft was 74% of the available runway length, indicating a reasonable use of the available space. The rollout phase was notable for its excellent alignment, with the aircraft maintaining a consistent path along the centreline. Overall, the landing was deemed satisfactory, earning a score of 90.0%.
