Landing on runway 33L at KBOS Logan International Airport in the B-2 Spirit

Landing Score 94.96 %

Landing Summary

The B-2 Spirit aircraft successfully landed at KBOS Logan International Airport on runway 33L, achieving a score of 95.0%. The aircraft approached the runway from the southeast, heading 305.0° at 3 nautical miles and 1,029 feet above ground level (agl). The pilot maintained a good threshold height, which is a critical aspect of a safe landing.

Upon touchdown, the aircraft's threshold speed was slightly above the target speed of 140 knots, indicating a slight over-speed. However, the touchdown speed of 122 knots was within the acceptable range, and the touchdown rate of -135 feet per minute (fpm) was smooth, suggesting a controlled descent. The touchdown point was 524 feet beyond the touchdown zone, which is a relatively minor deviation.

The runway touchdown position was slightly misaligned by 15 feet from the centerline, which may require some adjustments during the rollout phase. However, the runway rollout alignment was very good, indicating that the pilot maintained control of the aircraft during the post-landing phase.

The local weather conditions at the time of landing were characterized by a temperature of 22°F and a wind speed of 20 knots from 299°. The crosswind component was relatively minor at 5 knots, while the headwind component was 19 knots, which may have contributed to the slightly above-target threshold speed.

The total landing distance of 4,821 feet was 52% of the runway length, which is a relatively efficient use of the available runway. Overall, the landing was successful, and the pilot demonstrated good control and decision-making skills throughout the approach and landing phases.
