Departure

Use smaller, smoother aileron inputs to hold the climb bank angle near wings-level.

What happened: During Climb 3 the bank angle averaged 1.9°, well beyond a steady wings-level climb.

Watch for: Attitude indicator - bank angle, keeping it close to wings-level through the climb.

See Departure Climb 3

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.

The enroute level cruise began 2 miles east of Riviera Beach, Maryland, and lasted for 23 minutes, covering a distance of 174 nautical miles. The aircraft then started its enroute descent overhead Centerport, New York, and descended from an altitude of 31,021 feet above sea level to 1,303 feet above sea level, a decrease of 29,718 feet in 37 minutes, covering a distance of 142 nautical miles.

The final approach to runway 27 at Logan International Airport (KBOS) was made from the east, heading 257.0° at 4 nautical miles and 1,274 feet above ground level. The landing was made on runway 27, which had a length of 6,979 feet. The threshold height was above the target, and the threshold speed was slightly above the target at 150 knots.

The touchdown point was 1,024 feet beyond the touchdown zone, and the touchdown speed was 140 knots, which was a little fast. The touchdown rate was fair at -274 feet per minute. The runway touchdown position was misaligned by 26 feet from the centerline. The local weather conditions at the time of landing were a temperature of 32°F and a wind speed of 2 knots at 220°, with a crosswind of 1 knot and a headwind of 2 knots.

The total landing distance was 5,454 feet, which accounted for 78% of the runway length. The runway rollout alignment was slightly misaligned by 36 feet from the centerline. The taxiing period from the runway to the parking area took 3 minutes and covered a distance of less than 1 nautical mile. The total flight distance was 373 nautical miles, and the flight duration was 91 minutes, with a fuel consumption of 8,310 pounds.

Landing Summary

The Boeing 737-800 aircraft successfully landed at KBOS Logan International Airport, but with some minor deviations from the ideal landing parameters. The final approach was initiated from the east, heading 257.0° at a distance of 4 nautical miles and an altitude of 1,274 feet above ground level (agl). The aircraft touched down on runway 27, which has a length of 6,979 feet.

The threshold height at 60 feet agl was above the target, indicating that the aircraft was slightly higher than desired when reaching the runway threshold. Additionally, the threshold speed was slightly above the target at 150 knots, suggesting that the aircraft was moving at a slightly faster pace than intended when reaching the threshold. The touchdown point was 1,024 feet beyond the touchdown zone, which is a relatively significant deviation.

The touchdown speed of 140 knots was a little fast, indicating that the aircraft was not fully slowed down before touching down. However, the touchdown rate of -274 feet per minute (fpm) was considered fair, suggesting that the aircraft was able to absorb the impact of landing relatively smoothly. Unfortunately, the runway touchdown position was misaligned by 26 feet from the centreline, which may have contributed to the slightly fast touchdown speed.

The local weather conditions at the time of landing were relatively calm, with a temperature of 32°F and a wind speed of 2 knots from 220°. The crosswind component was minimal at 1 knot, while the headwind component was 2 knots. The total landing distance was 5,454 feet, which is 78% of the runway length. This is a relatively acceptable distance, considering the deviations from the ideal landing parameters.

During the rollout, the aircraft's alignment was slightly misaligned by 36 feet from the centreline, which may have been a result of the initial misalignment during touchdown. Overall, while the landing was not perfect, it was still considered successful, and the deviations from the ideal parameters were relatively minor.
