Arrival Touchdown — Touchdown rate was -639 fpm at 81 %, −0.26 points

Next time

Work on the flare

See Arrival Landing

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 04L at KBOS Logan International Airport in the Boeing 737-900
Landing Score 94.61 %
Landing Summary

The Boeing 737-900 aircraft successfully landed at KBOS Logan International Airport on runway 04L, achieving a score of 94.6%. The final approach was initiated from the south, heading 26.0° at a distance of 4 nautical miles and an altitude of 1,247 feet above ground level (agl).

The aircraft touched down on the runway with a good threshold height, indicating a smooth and controlled descent. The threshold speed of 142 knots was also within the acceptable range, demonstrating the pilot's ability to manage the aircraft's speed during the landing phase. However, the touchdown speed of 138 knots was slightly faster than desired, which may have contributed to a heavier touchdown rate.

The touchdown rate of -639 feet per minute (fpm) was considered heavy, indicating that the aircraft may have experienced a slight bounce or oscillation upon touchdown. This could be attributed to the slightly fast touchdown speed. Additionally, the runway touchdown position was slightly misaligned by 5.7 meters from the centerline, which may have been a result of the pilot's attempt to compensate for the crosswind.

The local weather conditions at the time of landing were characterized by a temperature of 3°C and a wind speed of 7 knots from 279°. The crosswind component was 7 knots, while the tailwind component was 1 knot. These conditions may have presented a challenge for the pilot, but they did not appear to significantly impact the landing.

The total landing distance of 1,583 meters was 74% of the available runway length, which is a relatively short distance. This suggests that the pilot was able to manage the aircraft's speed and descent rate effectively, allowing for a smooth and controlled landing. The runway rollout alignment was also very good, indicating that the pilot was able to maintain control of the aircraft during the rollout phase.

Overall, the landing was considered successful, with the aircraft touching down safely on the runway. However, there were some minor issues with the touchdown speed and rate, as well as the runway touchdown position. These areas can be addressed through further training and practice to improve the pilot's skills and reduce the risk of any potential issues during future landings.
