Arrival Touchdown — Touchdown distance was 1,933 ft at 86 %, −0.20 points

Next time

Departure

Roll the wings level with aileron and hold bank within limits as you establish the climb.

What happened: Bank increased to 1.8° during the initial climb, and wings stayed over-banked at 3.9° into the next climb segment.

Watch for: Attitude indicator bank angle, aiming to keep it near wings-level

See Departure Climb 2Departure Climb 3

Arrival

Begin the flare with progressive back pressure and keep it coming until the sink is arrested, rather than flying it on flat.

What happened: The nose was barely raised in the flare and little of the sink was taken out, flying the aircraft onto the runway. This pattern usually carries through to a firm touchdown with a noticeable sink rate.

Watch for: Vertical speed indicator: a smoothly reducing sink through the normal flare band, not a steady rate into the runway.

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 14 minutes and covered a distance of 4 nautical miles. The aircraft, a Boeing 737-MAX8, then departed from runway 28R at San Francisco International Airport (KSFO). The takeoff distance was 5,987 feet, which accounted for 52% of the runway. The aircraft lifted off at a speed of 147 knots.

As the aircraft climbed to its cruising altitude, it encountered local weather conditions of a temperature of 56°F and winds of 2 knots at 340°. The crosswind was 1 knot, and the headwind was also 1 knot. The enroute climb started overhead San Bruno, California, and the aircraft ascended from 1,045 feet above sea level to 34,461 feet above sea level, an increase of 33,416 feet in 15 minutes, covering a distance of 77 nautical miles.

The enroute level cruise began 5 miles south of Rancho Calaveras, California, and lasted for 152 minutes, covering a distance of 2,165 nautical miles. The aircraft then started its enroute descent 1 mile north of Williamstown, Massachusetts, and descended from 34,812 feet above sea level to 6,120 feet above sea level, a decrease of 28,692 feet in 14 minutes, covering a distance of 95 nautical miles.

The aircraft then entered another level cruise phase, this time starting overhead Stoneham, Massachusetts, and lasting for 3 minutes, covering a distance of 11 nautical miles. The enroute descent began 1 mile northwest of Boxford, Massachusetts, and the aircraft descended from 6,076 feet above sea level to 3,210 feet above sea level, a decrease of 2,866 feet in 3 minutes, covering a distance of 5 nautical miles.

The aircraft then entered another level cruise phase, starting 2 miles northeast of Topsfield, Massachusetts, and lasting for 3 minutes, covering a distance of 10 nautical miles. The enroute descent started 1 mile south of Peabody, Massachusetts, and the aircraft descended from 2,698 feet above sea level to 1,311 feet above sea level, a decrease of 1,387 feet in 2 minutes, covering a distance of 5 nautical miles.

The final approach to runway 22L at Logan International Airport (KBOS) began from the north, heading 200.0° at 4 nautical miles and 1,285 feet above ground level. The aircraft landed on the runway, which was 7,641 feet long. The threshold height was above the target, but the threshold speed was good at 130 knots.

The touchdown point was 554 feet beyond the touchdown zone, and the touchdown speed was 124 knots, which was a little fast. The touchdown rate was fair at -290 feet per minute. The runway touchdown position was slightly misaligned by 16 feet from the centerline. The local weather conditions at the time of landing were a temperature of 34°F and winds of 3 knots at 200°, with a crosswind of 0 knots and a headwind of 3 knots.

The total landing distance was 3,958 feet, which accounted for 52% of the runway. The runway rollout alignment was very good. The taxiing period from the runway to the parking took 3 minutes and covered less than 1 nautical mile. The total flight distance was 2,378 nautical miles, and the flight duration was 208 minutes, with a fuel consumption of 22,578 pounds.

Landing on runway 22L at KBOS Logan International Airport in the Boeing 737 MAX 8
Landing Score 90.29 %
Landing Summary

The Boeing 737-MAX8 aircraft successfully landed at KBOS Logan International Airport on runway 22L, achieving a score of 90.3%. The final approach was initiated from the north, heading 200.0° at a distance of 4 nautical miles and an altitude of 1,285 feet above ground level (agl).

Upon landing, the aircraft touched down 554 feet beyond the touchdown zone, which is slightly outside the designated area. The touchdown speed of 124 knots was a bit faster than the target speed, indicating that the pilot may have needed to apply more braking force to slow down the aircraft. However, the touchdown rate of -290 feet per minute (fpm) was considered fair, suggesting that the pilot managed to control the descent effectively.

The runway touchdown position was slightly misaligned by 16 feet from the centerline, which may have been due to a slight deviation in the pilot's approach or a minor issue with the aircraft's navigation system. Despite this, the runway rollout alignment was very good, indicating that the pilot maintained control of the aircraft during the rollout phase.

The local weather conditions at the time of landing were relatively calm, with a temperature of 34°F and a wind speed of 3 knots from 200°. The crosswind component was negligible, and the headwind component was 3 knots, which may have contributed to the slightly faster touchdown speed.

Overall, the landing was considered successful, with the aircraft coming to a stop within 52% of the runway length. However, there is room for improvement in terms of touchdown speed and alignment, which can be addressed through further training and practice.
