1.10 G at touchdown — inside band
Rollout controlled — 42 % of the runway used

What held you back

Departure Taxi — peak taxi speed 48 kt at 12 %, peak speed in a turn 21 kt at 48 %, −3.75 points
Enroute Climb — speed limits at 0 %, −2.67 points
Arrival Taxi — landing lights; Taxi Lights at 0 %, peak taxi speed 47 kt at 17 %, −2.35 points
Arrival Landing — GPWS warning; Flare profile at 2 %, Threshold height at 66 ft agl was above target at 76 %, −1.30 points

Next time

Departure

Ease the nose up sooner to lift off at 166 kt instead of letting speed build on the ground.

What happened: The aircraft lifted off at 188 kt, 22 kt above the target liftoff speed.

Watch for: Airspeed indicator: 166 kt at liftoff

See Departure Roll

Arrive slow and the sink rate at the threshold is already above schedule, the flare is short because there is no energy to extend it, and the touchdown is hard in a way that feels exactly like a late flare. Diagnosing a slow arrival as a late flare is the catastrophic misread: you respond by flaring earlier, which bleeds more speed, which makes the next one worse. The tiebreaker is threshold speed against VRef, not feel. Never diagnose a flare without it.

Landing on runway 27L at EGLL London Heathrow Airport in the Boeing 777-300ER
Landing Score 88.28 %
Landing Summary

The Boeing 777-300 aircraft successfully landed on runway 27L at EGLL London Heathrow Airport, achieving an overall score of 88.3%. The final approach to the runway was initiated from the east, with the aircraft heading 271.0° at a distance of 4 nautical miles and an altitude of 1,242 feet above ground level (agl).

Upon landing, the aircraft touched down on the runway at a speed of 137 knots, which was within the acceptable range. The touchdown rate was also smooth, at -124 feet per minute (fpm), indicating a controlled descent. However, the touchdown point was located 323 meters beyond the designated touchdown zone, which may require further analysis to determine the cause of the deviation.

The threshold height at 66 feet agl was above the target, suggesting that the aircraft may have been slightly high on final approach. Nevertheless, the threshold speed was good at 145 knots, indicating that the pilot maintained control and adhered to the recommended approach speed.

The local weather conditions at the time of landing were characterized by a temperature of -4°C and a wind speed of 4 knots from 270°. The crosswind component was negligible, at 0 knots, while the headwind component was 3 knots. These conditions were relatively calm, which may have contributed to the smooth touchdown and rollout.

The runway rollout alignment was very good, indicating that the pilot maintained control and aligned the aircraft with the centerline of the runway. However, the runway touchdown position was slightly misaligned by 7.4 meters from the centerline, which may require further attention to ensure that the aircraft is properly aligned with the runway.

The total landing distance was 1,435 meters, which accounted for 43% of the runway length. This is a relatively short landing distance, considering the aircraft's size and weight. Overall, the landing was successful, and the pilot demonstrated good control and adherence to standard operating procedures.
