Good threshold height.

Threshold speed

100 %

Threshold speed was slightly above target at 155 kt.

Flare

100 %

The flare tracked the target profile exactly. Crossing the threshold 12 kt above target, the flare began at 10 ft agl above the runway, lower than this type wants. Touchdown was 449 ft past the threshold. Begin raising the nose earlier - a late flare leaves no time to arrest the sink.

Landing on runway 19C at KIAD Washington Dulles International Airport in the Boeing 737-800

Landing Score 89.69 %

Landing Summary

The Boeing 737-800 entered the final approach to runway 19C at KIAD from the north on a heading of 180.0° at 4 NM and 1,222 ft AGL. The approach was assessed as stabilised at the 1,000 ft gate, with gear, flaps, sink rate, glideslope and centreline all within limits.

During the threshold and flare phase the aircraft maintained a good threshold height. Threshold speed was slightly above target at 155 kt and the flare resulted in a touchdown distance of 458 ft. Touchdown speed was a little fast at 153 kt, the vertical rate was heavy at minus 690 fpm, and the touchdown point was misaligned by 27 ft from the centreline.

At touchdown the aircraft touched down 458 ft down the runway at 153 kt, with a heavy sink rate of minus 690 fpm and a lateral offset of 27 ft from the centreline. The speed was marginally above the desired value, but the gear and flaps remained correctly configured.

Rollout proceeded with very good alignment and the aircraft used a total landing distance of 4,721 ft, representing 41 % of the 11,499-ft runway length.

To refine the performance, focus on reducing the vertical touchdown rate by fine-tuning flare timing, and aim to centre the aircraft more precisely on the runway centreline to eliminate the 27-ft offset. Maintaining the current stabilised approach will support these adjustments and preserve the strong overall score.
