Next time

Departure

Make small rudder corrections against a point at the far end to hold the centreline.

What happened: During the ground roll you drifted 6.9 m off the runway centreline.

Watch for: Watch runway alignment against the centreline, correcting with small rudder inputs.

See Departure Roll

Arrival

Keep the back pressure coming through the flare so the sink does not return at 197 fpm.

What happened: The flare arrested the sink, but then the sink returned before touchdown.

Watch for: Watch the VSI in the flare and keep arrested sink from returning before touchdown at 274 fpm.

See Arrival Landing

Twenty knots on a monitor produces the visual sensation of about ten. The advice to "taxi at a walking pace" cannot fix this, because your sense of walking pace is exactly the thing that's broken. Put the groundspeed readout in your scan and obey it for the next fifty flights, the way a student pilot leans on the airspeed indicator before learning to read attitude.

The aircraft then began another enroute climb, this time from 35,001 feet above sea level to 36,995 feet above sea level, an increase of 1,995 feet in 3 minutes, covering a distance of 31 nautical miles. The enroute level cruise resumed at a latitude of 55.8730458 and a longitude of 173.500908, lasting 207 minutes and covering 1,846 nautical miles.

The aircraft then began another enroute climb, this time from 36,994 feet above sea level to 38,998 feet above sea level, an increase of 2,004 feet in 3 minutes, covering a distance of 31 nautical miles. The enroute level cruise resumed 31 miles northeast of Deline, Northwest Territories, Canada, lasting 251 minutes and covering 2,147 nautical miles.

As the aircraft approached its destination, it began its enroute descent, starting overhead Cropseyville, New York, and descending from 39,019 feet above sea level to 1,305 feet above sea level, a decrease of 37,714 feet in 27 minutes, covering a distance of 141 nautical miles. The final approach to runway 33L at KBOS Logan International Airport was made from the southeast, heading 315.0 degrees at 4 nautical miles and 1,278 feet above ground level.

Landing Score 98.06 %
Landing Summary

The Boeing 777-200ER aircraft successfully landed at KBOS Logan International Airport on runway 33L, demonstrating a high level of precision and control. The final approach was initiated from the southeast, heading 315.0° at a distance of 4 nautical miles and an altitude of 1,278 feet above ground level (agl). The aircraft's approach speed and altitude were well within the acceptable parameters, setting the stage for a smooth touchdown.

Upon landing, the aircraft touched down 166 meters beyond the touchdown zone, which is a relatively minor deviation. However, the touchdown speed of 121 knots was within the acceptable range, and the touchdown rate of -163 feet per minute (fpm) was also satisfactory. The runway touchdown alignment was perfect, indicating that the aircraft was properly aligned with the runway centerline at the moment of touchdown.

The local weather conditions at the time of landing were characterized by a temperature of -2°C and a wind speed of 8 knots from 312°. This resulted in a headwind of 8 knots, which had a negligible impact on the aircraft's performance. The crosswind component was effectively zero, allowing the pilots to maintain a stable approach and landing.

The total landing distance of 1,503 meters was 54% of the runway length, which is a relatively short distance considering the aircraft's size and weight. This suggests that the pilots were able to maintain a high level of control and precision throughout the landing, allowing the aircraft to come to a stop in a relatively short distance. The runway rollout alignment was also perfect, indicating that the aircraft was properly aligned with the runway centerline during the rollout phase.

Overall, the landing of the Boeing 777-200ER at KBOS Logan International Airport was a textbook example of precision and control. The pilots' skills and experience were evident in the smooth and controlled approach and landing, which resulted in a high level of safety and efficiency.
