What went well

Touched down at -258 fpm — a soft arrival
Straight touchdown — 5.3 ft off the centreline, no bounce
1.22 G at touchdown — inside band

What held you back

Arrival Landing — Flare profile at 0 %, −1.13 points
Arrival Touchdown — Touchdown distance was 2,703 ft at 60 %, −0.31 points
Arrival Rollout — Runway alignment max 17.2 ft left at 92 %, −0.15 points

Next time

Arrival

Keep the back pressure coming once the flare is established, holding the nose up through to touchdown instead of easing it.

What happened: The flare arrested the sink but 110 fpm of it came back before touchdown, and in flights like this one that returning sink usually carries through to a firm or hard touchdown at 252 fpm.

Watch for: Vertical speed indicator: the sink held near zero all the way through touchdown, not allowed to build back up.

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 area to the runway, which took 10 minutes and covered less than 1 nautical mile. The aircraft, a Boeing 737-800, then departed from runway 22R at KBOS Logan International Airport. The takeoff distance was 3,411 feet, which accounted for 48% of the runway. The liftoff speed was 150 knots.

The local weather conditions at the time of departure were characterized by a temperature of 38 degrees Fahrenheit, with a wind speed of 4 knots from a direction of 210 degrees. This resulted in a crosswind of 1 knot and a headwind of 3 knots. The aircraft then began its enroute climb, which started overhead the MA17 Avco/Lowell Heliport in Lowell, Massachusetts. The climb took 13 minutes and covered 37 nautical miles, during which the aircraft ascended from an altitude of 1,020 feet above sea level to 28,228 feet above sea level, an increase of 27,207 feet.

Following the enroute climb, the aircraft entered a level cruise phase, which began 1 mile northwest of Auburn, Massachusetts. This phase lasted for 34 minutes and covered 221 nautical miles. The aircraft then started its enroute descent, which began 2 miles south of Wernersville, Pennsylvania. The descent took 26 minutes and covered 99 nautical miles, during which the aircraft descended from an altitude of 28,154 feet above sea level to 1,578 feet above sea level, a decrease of 26,577 feet.

The final approach to runway 19L at KIAD Washington Dulles International Airport was made from the north, with a heading of 181.0 degrees at an altitude of 4 nautical miles and 1,252 feet above ground level. The landing was made on runway 19L, which had a length of 11,513 feet. The threshold height at 59 feet above ground level was slightly above the target, and the threshold speed was also slightly above the target at 145 knots.

The touchdown point was 1,374 feet beyond the touchdown zone, and the touchdown speed was 137 knots, which was a little fast. However, the touchdown rate was fair at -258 feet per minute, and the runway touchdown alignment was very good. The local weather conditions at the time of landing were characterized by a temperature of 41 degrees Fahrenheit, with a wind speed of 2 knots from a direction of 0 degrees. This resulted in a tailwind of 2 knots.

The total landing distance was 6,028 feet, which accounted for 52% of the runway. The runway rollout alignment was also very good. The taxiing period from the runway to the parking area took 13 minutes and covered less than 1 nautical mile. The total flight distance was 367 nautical miles, and the flight duration was 105 minutes. The aircraft used 9,482 pounds of fuel during the flight.

Landing Summary

The Boeing 737-800 aircraft successfully landed at KIAD Washington Dulles International Airport on runway 19L. The final approach was initiated from the north, heading 181.0° at a distance of 4 nautical miles and an altitude of 1,252 feet above ground level (agl). The aircraft maintained a steady course throughout the approach, with a slight deviation in threshold height, being 59 feet agl, which was slightly above the target.

Upon touchdown, the aircraft's speed was recorded at 137 knots, which was a little fast, but still within acceptable limits. The touchdown rate of -258 feet per minute (fpm) was considered fair, indicating a relatively smooth landing. The runway touchdown alignment was very good, demonstrating the pilot's skill and control during the final stages of the approach.

The local weather conditions at the time of landing were favorable, with a temperature of 41°F and a wind speed of 2 knots at 0°. This resulted in a negligible crosswind component and a slight tailwind of 2 knots, which did not significantly impact the landing. The total landing distance of 6,028 feet was 52% of the runway length, indicating a relatively long landing roll. However, the runway rollout alignment was very good, suggesting that the pilot maintained control and alignment throughout the rollout phase.

Overall, the landing was considered successful, with a score of 90.5%. While there were some minor deviations from the target parameters, the pilot's skills and the aircraft's performance ensured a safe and controlled landing.
