What went well

Touched down at -240 fpm — a soft arrival
1.17 G at touchdown — inside band
Lifted off at 181 kt — on the 166 kt rotation target

What held you back

Arrival Landing — Flare profile at 0 %, Threshold height at 66 ft agl was above target at 76 %, −1.30 points
Arrival Rollout — Runway alignment max 15.34 m left at 55 %, −0.95 points
Arrival Touchdown — Touchdown distance was 705 m at 73 %, bank angle up to 3.4 ° at 83 %, −0.29 points

Next time

Departure

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

What happened: During Climb 3 the bank angle averaged 3.8°, 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

Arrival

Fly the flare as one continuous check of the sink rate from 16 ft, holding back pressure steadily rather than adjusting pitch piecemeal.

What happened: The flare drifted away from its intended profile rather than tracking it smoothly from 16 ft down to touchdown.

Watch for: Watch radio altitude and VSI through the flare, aiming to arrest the sink smoothly from 16 ft to touchdown.

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 11 minutes and covered a distance of 3 nautical miles. The aircraft, a Boeing 737-900, then departed from runway 01 at Keflavik International Airport (BIKF) in Iceland. The takeoff distance was 2,090 meters, which was 69% of the runway length. The liftoff speed was 182 knots, and the local weather conditions at the time of departure were a temperature of 14°C, with a wind speed of 8 knots at a direction of 20°.

The aircraft then began its enroute climb, starting 1 mile west of Reykjanesbaer in Iceland. The climb took 17 minutes and covered a distance of 99 nautical miles, during which the aircraft ascended from an altitude of 1,118 feet above sea level to 28,674 feet above sea level, an increase of 27,557 feet. The enroute level cruise then began 98 miles southwest of Sandgerdi in Iceland and lasted for 273 minutes, covering a distance of 1,906 nautical miles.

As the aircraft approached its destination, it began its enroute descent, starting 19 miles south of Phippsburg in Maine, United States. The descent took 24 minutes and covered a distance of 94 nautical miles, during which the aircraft descended from an altitude of 30,882 feet above sea level to 1,305 feet above sea level, a decrease of 29,577 feet. The final approach to runway 04R at Logan International Airport (KBOS) was made from the south, with a heading of 20.0° at an altitude of 1,275 feet above ground level and a distance of 4 nautical miles from the runway.

The landing on runway 04R was successful, with a touchdown speed of 142 knots, which was a little fast. The touchdown point was 297 meters beyond the touchdown zone, and the runway touchdown position was slightly misaligned by 4.6 meters from the centerline. The local weather conditions at the time of landing were a temperature of 21°C, with a wind speed of 3 knots at a direction of 220°. The crosswind was 1 knot, and there was a tailwind of 3 knots.

The total landing distance was 1,778 meters, which was 76% of the runway length. The runway rollout alignment was misaligned by 15.3 meters from the centerline. The taxiing period from the runway to the parking took 6 minutes and covered a distance of less than 1 nautical mile. The total flight distance was 2,109 nautical miles, and the flight duration was 332 minutes. The aircraft used a total of 15,385 kilograms of fuel during the flight.

Landing on runway 04R at KBOS Logan International Airport in the Boeing 737-900
Landing Score 84.68 %
Landing Summary

The Boeing 737-900 aircraft successfully landed at KBOS Logan International Airport on runway 04R, but with some minor deviations from the ideal landing parameters. The aircraft was approaching the runway from the south, heading 20.0° at a distance of 4 nautical miles and an altitude of 1,275 feet above ground level (agl). The final approach was executed at a speed of 146 knots, which was within the target threshold speed.

However, the aircraft touched down 297 meters beyond the touchdown zone, which is slightly outside the desired area. The touchdown speed of 142 knots was also a bit faster than the ideal speed, indicating that the pilot may have applied a bit too much reverse thrust or braking. The touchdown rate of -240 feet per minute (fpm) was fair, but not exceptional.

The runway touchdown position was also slightly misaligned by 4.6 meters from the centerline, which may have been due to a slight deviation in the aircraft's heading or a minor error in the pilot's alignment. The local weather conditions were relatively calm, with a temperature of 21°C and a wind speed of 3 knots at 220°. The crosswind component was minimal at 1 knot, while the tailwind component was 3 knots.

The total landing distance of 1,778 meters was 76% of the runway length, which is a reasonable distance considering the aircraft's weight and the runway's length. However, the runway rollout alignment was also misaligned by 15.3 meters from the centerline, which may have been due to a slight deviation in the aircraft's heading or a minor error in the pilot's alignment.

Overall, the landing was successful, but with some minor deviations from the ideal parameters. The pilot may have benefited from a bit more practice or attention to detail to achieve a more precise landing.
