What went well

Touched down at -254 fpm — a soft arrival
Threshold crossed at 54 ft and 149 kt — both inside band
Straight touchdown — 12.9 ft off the centreline, no bounce

What held you back

Arrival Landing — Flare profile at 0 %, −1.04 points
Arrival Touchdown — Touchdown distance was 2,476 ft at 67 %, −0.27 points
Arrival Taxi — Taxi Lights at 0 %, −0.21 points

Next time

Arrival

Start the flare with progressive back pressure and keep it coming until the sink is arrested.

What happened: The aircraft was flown onto the runway: the nose was barely raised and little of the sink was taken out, touching down at 254 fpm.

Watch for: Pitch attitude: rising steadily through the flare until the sink is checked.

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.

Flight narrative

The flight began with a taxiing period from the parking to the runway, which took 13 minutes and covered a distance of 2 nautical miles. The aircraft, a Boeing 737-800, then departed from runway 27R at Philadelphia International Airport (KPHL). The takeoff distance was 4,267 feet, which was 45% of the runway length. The liftoff speed was 161 knots.

The local weather conditions at the time of departure were characterized by a temperature of 81°F and a wind speed of 4 knots from a direction of 340°. The crosswind component was 4 knots, while the headwind component was 0 knots. As the aircraft climbed to its cruising altitude, it encountered a series of enroute climbs and descents, which were interspersed with periods of level cruise.

The first enroute climb started 1 mile south of Folcroft, Pennsylvania, and took the aircraft from an altitude of 1,077 feet above sea level (asl) to 22,999 feet asl, an increase of 21,922 feet in 12 minutes and covering a distance of 69 nautical miles. The enroute level cruise that followed started 3 miles east of Sea Bright, New Jersey, and lasted for 25 minutes, covering a distance of 207 nautical miles.

The aircraft then began its descent from 22,563 feet asl to 9,286 feet asl, a decrease of 13,277 feet in 11 minutes and covering a distance of 47 nautical miles. This was followed by a brief period of level cruise, which started 19 miles east of Rockport, Massachusetts, and lasted for 3 minutes, covering a distance of 12 nautical miles.

The next descent started 9 miles southeast of Rockport and took the aircraft from 8,990 feet asl to 5,121 feet asl, a decrease of 3,869 feet in 7 minutes and covering a distance of 21 nautical miles. The aircraft then entered another period of level cruise, which started 3 miles northeast of Hull, Massachusetts, and lasted for 2 minutes, covering a distance of 5 nautical miles.

The final descent started 2 miles northeast of Cohasset, Massachusetts, and took the aircraft from 4,873 feet asl to 4,350 feet asl, a decrease of 523 feet in 2 minutes and covering a distance of 6 nautical miles. The aircraft then entered another period of level cruise, which started 3 miles east of Scituate, Massachusetts, and lasted for 2 minutes, covering a distance of 3 nautical miles.

The final descent started 2 miles northeast of Marshfield Hills, Massachusetts, and took the aircraft from 4,168 feet asl to 1,283 feet asl, a decrease of 2,885 feet in 6 minutes and covering a distance of 13 nautical miles. The aircraft then began its final approach to runway 33L at Logan International Airport (KBOS), which was located to the southeast.

The final approach was made at a heading of 315.0°, 4 nautical miles from the runway, and at an altitude of 1,254 feet above ground level (agl). The landing was made on runway 33L, which had a length of 9,200 feet. The threshold speed was slightly above the target speed of 150 knots, and the touchdown point was 1,127 feet beyond the touchdown zone. The touchdown speed was 142 knots, which was a little fast, and the touchdown rate was fair at -220 feet per minute (fpm).

The runway touchdown position was slightly misaligned from the centerline by 13 feet. The local weather conditions at the time of landing were characterized by a temperature of 73°F and a wind speed of 9

Landing Summary

The Boeing 737-800 aircraft successfully landed at KBOS Logan International Airport on runway 33L. The final approach was initiated from the southeast, heading 315.0° at a distance of 4 nautical miles and an altitude of 1,254 feet above ground level (agl). The aircraft maintained a good threshold height, which is a crucial aspect of a safe landing.

Upon touchdown, the aircraft's threshold speed was slightly above the target speed of 150 knots, indicating a slight deviation from the ideal landing speed. However, the touchdown speed of 142 knots was a bit faster than desired, which may have contributed to a slightly higher touchdown rate of -220 feet per minute (fpm). Despite this, the touchdown rate was still considered fair.

The touchdown point was located 1,127 feet beyond the touchdown zone, which is a relatively long distance. This may be attributed to the aircraft's slightly fast touchdown speed. The runway touchdown position was also slightly misaligned by 13 feet from the centerline, which could have been a result of the crosswind or pilot error.

The local weather conditions at the time of landing were favorable, with a temperature of 73°F and a wind speed of 9 knots from 341°. The crosswind component was minimal at 4 knots, while the headwind component was 8 knots. These conditions likely contributed to a smooth landing.

The total landing distance of 5,754 feet was 63% of the runway length, which is a relatively long distance. However, the runway rollout alignment was very good, indicating that the aircraft was well-controlled during the landing roll. Overall, the landing was considered successful, with some minor deviations from the ideal landing parameters.
