Next time

Departure

Use smooth aileron to roll the wings level in the first climb segment, holding bank angle near wings-level instead of letting it build to 5.9°.

What happened: The wings held 5.9° of bank through the first climb segment and had drifted to 4.3° by the second - this early wing-level drift usually carries through into a larger bank excursion later in the climb.

Watch for: Watch the attitude indicator's bank pointer and keep it at wings level throughout the climb.

See Departure Climb 1Departure Climb 2Departure Climb 3

Arrival

Begin raising the nose earlier, by 11 ft, so the flare has time to arrest the sink before touchdown.

What happened: The flare began late at 0.5 ft, 11 ft below the normal band, and a late flare like this usually leaves too little time to arrest the sink before touchdown.

Watch for: Watch radio altitude and start the flare in the normal band, around 11 ft.

See Arrival LandingArrival Touchdown

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 8 minutes and covered a distance of 2 nautical miles. The aircraft, a Boeing 737-800, then departed from runway 08 at KDEN Denver International Airport. The takeoff distance was 2,511 meters, which accounted for 69% of the runway. The aircraft lifted off at a speed of 155 knots.

As the aircraft climbed to its cruising altitude, it encountered local weather conditions of a temperature of 20 degrees Celsius and a wind speed of 6 knots at 90 degrees. The crosswind was negligible, but the aircraft experienced a headwind of 6 knots. The enroute climb started 3 miles southwest of CO3 Greggs Nr 1 Airport Bennett, where the aircraft climbed from 6,300 feet above sea level to 34,803 feet above sea level, an increase of 28,503 feet in 24 minutes, covering a distance of 179 nautical miles.

After reaching its cruising altitude, the aircraft entered a level cruise phase, which started 3 miles northeast of 62NE Beebe Airport Hayes Center. This phase lasted for 158 minutes, covering a distance of 1,244 nautical miles. The aircraft then began its descent, starting 2 miles northeast of Williamstown, Massachusetts. The descent from 32,879 feet above sea level to 2,719 feet above sea level, a decrease of 30,160 feet in 22 minutes, covered a distance of 116 nautical miles.

The aircraft then entered another level cruise phase, which started 1 mile east of Avon, Massachusetts, and lasted for 3 minutes, covering a distance of 9 nautical miles. The aircraft then began its final descent, starting 2 miles south of Milton, Massachusetts. The descent from 2,691 feet above sea level to 1,298 feet above sea level, a decrease of 1,393 feet in 3 minutes, covered a distance of 5 nautical miles.

The final approach to runway 04R at KBOS Logan International Airport was made from the south, heading 20.0 degrees at 4 nautical miles and 1,272 feet above ground level. The aircraft landed on the runway, which had a length of 2,329 meters. The threshold height was good, and the threshold speed was also good at 143 knots. However, the touchdown speed was a little fast at 143 knots, and the touchdown rate was heavy at -691 feet per minute. The runway touchdown position was slightly misaligned by 3.1 meters from the centreline.

The total landing distance was 1,404 meters, which accounted for 60% of the runway. The runway rollout alignment was misaligned by 17.6 meters from the centreline. The taxiing period from the runway to the parking took 5 minutes and covered a distance of 1 nautical mile. The total flight distance was 1,565 nautical miles, taking 224 minutes, and the aircraft used 9,312 kilograms of fuel.

Landing on runway 04R at KBOS Logan International Airport in the Boeing 737-800
Landing Score 88.79 %
Landing Summary

The Boeing 737-800 aircraft successfully landed at KBOS Logan International Airport on runway 04R, achieving an overall score of 88.8%. The final approach was initiated from the south, heading 20.0° at a distance of 4 nautical miles and an altitude of 1,272 feet above ground level (agl). The aircraft maintained a good threshold height, indicating a stable approach.

Upon touchdown, the threshold speed was recorded at 143 knots, which was within the acceptable range. However, the touchdown speed of 143 kt was slightly faster than desired, suggesting that the pilot may have been able to flare the aircraft more effectively to achieve a smoother touchdown. The touchdown distance of 165 meters was also within the acceptable range.

Despite the good threshold speed and touchdown distance, the touchdown rate was heavy at -691 feet per minute (fpm), indicating a steeper-than-desired descent rate. This may have been due to the pilot's attempt to maintain a stable approach despite the challenging weather conditions.

The local weather at the time of landing was characterized by a temperature of -7°C and a wind speed of 14 knots from 310°. The crosswind component was 13 kt, while the headwind component was 5 kt. These conditions may have contributed to the heavy touchdown rate and the slight misalignment of the runway touchdown position, which was 3.1 meters off-centerline.

The total landing distance of 1,404 meters was 60% of the runway length, indicating a relatively short landing distance. However, the runway rollout alignment was misaligned by 17.6 meters from the centerline, suggesting that the pilot may have experienced some difficulty in maintaining a stable rollout.

Overall, the landing was successful, but there were some areas for improvement, particularly in terms of touchdown speed and touchdown rate. The pilot's ability to adapt to the challenging weather conditions and maintain a stable approach was commendable, but further training may be necessary to refine the pilot's skills in these areas.
